Organism Adaptations 1)stimulus: a change in the environment that necessities a response, or adjustment by an organism (ex. swirling dust) response: the adjustment or change you make to a stimulus (ex. blinking your eyes) 2)Protists respond to a negative stimuli by moving away from it. Protists respond to: light, irritating chemicals, temperature, touch, etc. 3)Yes, they grow towards the stimulus (ex. light). photoropism: it means the organism grows towards the light. no geotropism: it means the organism grows towards the ground. no 4)This is because animals have the most highly developed sensory systems of all organisms. 5)Three factors that affect an organism's response are the type, number, and complexity of an animal's sense organs. The way they affect the response is determined by the type, number, and complexity of the animal's sense organs. 6)positive: food, money negative: a man pointing a gun at you neutral: sound of traffic 7)In general, organisms go towards positive stimuli, and go away from n egative one. 8)voluntary: eating a bowl of hot chicken soup involuntary: watering of your mouth learned: talking 9)When an animal receives a scare, it can either Fight, Flight (go away from), Freeze the/from organism that is scaring that animal. The animal releases adrenaline that gives it the strength to do one of those things. pg. 136 #3,4,challenger) 3)automatic: i)blinking your eyes when dust gets in them ii)mouth waters when you smell food iii)moving your hand away when it gets burned voluntary: i)eat a bowl of soup ii)drink water iii)watching TV 4)The stimulus. You need the stimulus to make a response. b)No, it is not possible. This is because with an action, there is a reaction. No, you need a stimuli to make a response, otherwise it is not really a response. 5)i)it comes out of the ground ii)it crows iii)it barks and chases the perpetrator iv)it chases and eats a gazelle b)i)the flooding of its home ii)getting light iii)the person breaking in iv)its hunger Challenger It help s to keep the brain and heart from freezing. pg. 146 #1-5) 1)i)taste ii)touch iii)sight iv)smell v)hearing 2)The protists can only sense chemical. 3)This effect is called sensory adaptation. b)An advantage is that you aren't bothered by the smell. A disadvantage is if you are accustomed to the smell of smoke, the smell of smoke might not alert you if your house is on fire. b)cone: when it is light out rod: when it is dark out c)They aren't as developed as some other organisms. 5)Eyelid: this is because your hell cells are very tough from being walked on. This causes them not to be very sensitive. 5-6-1993 pg.13 #1-6) 1)environment: everything in an organism's surroundings biotic environment: all living things in an environment abiotic environment: non living things in an environment 2)When you breathe, your body extracts oxygen from the air. b) large animal eats smaller animal smaller animals larger animal dies and eats plants fertilizes ground soil grows plants 3)biology,ecology: they are the study of things on earth; ecology is the study of environment, biology is the study of animals b)producers,consumers: they live off the environment; pro. manufactures food, con. can't manufacture other food, but eat other organisms c)scavenger,decomposer: both live of off dead organisms; decom. break down the bodies of dead organisms d)habitat,niche: have to do with were an animal lives hab.=enviro. space were an organism lives, niche = way an organism reacts with its environment e)environment,ecosystem: were organisms live; enviro.= everything in an organism's surroundings, eco.= were organisms of a distinct group interact 4)a)auto b)hetro c) auto d)auto e)auto f)hetro 5)biosphere: layer of planet where living things exist and interact b)lithosphere: solid portion of the Earth's surface c)hydrosphere: layer of water that covers nearly 3/4 of the Earth's surface d)atmosphere: mass of air surroundin g the Earth 6)The scavengers come and totally eat the carcass.

Definition of Subject for Spanish Students

Definition of Subject for Spanish Students Traditionally, the subject is the part of the sentence that performs the action of the main verb of a sentence. Sometimes, subject is used to refer specifically to the noun or pronoun that performs the action of the verb. In Spanish (rarely in English except in commands), it is common also for the subject to be implied rather than directly stated. In the following sentences, the subject is in boldface. Examples El hombre canta bien. The man sings well. (The noun hombre is performing the action of the verb canta.)Los jugadores no estn con nosotros. The players arent with us. (The noun jugadores is performing the action of the verb estn.)Ellos no estn con nosotros. They arent with us. (The subject is a pronoun.)No estn con nosotros. They arent with us. (The subject here in the Spanish sentence is implied to be ellos but isnt directly stated. In translation, the pronoun here must be stated in English.) The subject of a verb can be contrasted with its object, which receives the action of the verb rather than performs it. The subject of the sentence sometimes is considered to include not just the noun, but all the words in the phrase that accompanies the noun. By this definition, el hombre in the first sample sentence can be considered the subject of the sentence. By this definition, the subject of a sentence can get quite complex. For example, in the sentence La chica que va al teatro no me conoce (the girl who is going to the theater doesnt know me), la chica que va al teatro can be considered the full subject. By this definition, the subject of a sentence can be contrasted with the predicate of a sentence, which includes the verb and often the object of the verb and related words. In Spanish, the subject and verb (or predicate) match in number. In other words, a singular subject must be accompanied by a verb that is conjugated in a singular form, and a plural subject takes a plural verb. Although the subject is usually thought of as the performer of a sentences action, in passive sentences this may not be the case. For example, in the sentence su tà ­o fue arrestado (her uncle was arrested), tà ­o is the subject of the sentence even though some unspecified person or persons are performing the verbs action. In Spanish, as in English, the subject typically comes before the verb except in questions. However, in Spanish, it is not extraordinary for the verb to come before the subject even in direct statements. For example, in the sentence me amaron mis padres (my parents loved me), padres (parents) is the subject of the verb amaron (loved). Sample Sentences Un planeta es un cuerpo celeste que orbita alrededor de una estrella. A planet is a heavenly body that orbits around a star.No comprendo la revuelta rabe. I dont understand the Arab revolt. (The subject in the Spanish sentence is implied.)Yo y tà º podemos hacer todo. You and I can do everything. (This is the use of a compound subject.)Me gustan las enchiladas. I like enchiladas. (In the Spanish sentence, the subject here comes after the verb. Note that in translation, the subject in English represents a different word.)Hoy empieza la revolucià ³n. The revolution begins today. (The subject comes after the verb. Although hoy is sometimes a noun, here it is an adverb.)Skype fue comprado por Microsoft. Skype was bought by Microsoft. (In this passive sentence, Skype is the subject even though it is not performing the verbs action.)

Labor Relations & Deregulation Essay Example | Topics and Well Written Essays - 250 words

Labor Relations & Deregulation - Essay Example Between 1978 and 1985, wages for airline mechanics fell significantly. Deregulation led to increase of computerization in the air industry. This was commonly used in cutting down transaction costs on the airline industry. It led to massive unemployment since computers replaced most of human labor (Kaps, 15). One of the major benefits of airline deregulations was the fact that employees who had lost their jobs during the deregulation phase, enjoyed greater unemployment benefits that were provided to them in the 1978 Act. This was included in order to appease the workers. On the other hand, airline companies improved benefits for their customers while increasing competition among airline service providers (Kaps, 18). Airline labor union bargaining powers became reduced after the deregulation. Before the deregulation, the union managed to advocate for wage inrease, efficient and friendly working rules and working conditions. After the deregulation, many workers faced improper and harsh working conditions and rules. These workers also faced irregular job losses. In conclusion, airline workers found themselves having fewer jobs and high demand on their productivity. The airline labor union role and powers were diminished and regulated. While the airline industry has become more productive and affordable to its consumers, laborers have lost jobs and wages and benefits reduced (Kaps,

Being the Bridge Essay Example | Topics and Well Written Essays - 250 words

Being the Bridge - Essay Example The CIO can also engage representatives from other departments to discuss pertinent issues that may affect the operations of the company as a whole. Customer relationship management has become a priority for many CIOs. Essentially, the underlying concept in marketing is related to satisfaction of customer needs. Therefore, outstanding companies seek to learn and understand the needs and wants of the customers (Kotler & Armstrong, 2010). Loyalty among the customers is created where there is quality relationship with the firm that exists. The success of the company mainly depends on the number of customers that exist. Whenever customers are treated as valuable assets to the company, they can identify with it. This also helps them refer others to the firm. More revenue is likely to be generated if the company is sensitive to the needs of the customers. This can also help to ensure the viability and sustainability of the company in the long run in its

Analysis of Interpersonal Relationship Development Essay

Analysis of Interpersonal Relationship Development - Essay Example to know each other, through first â€Å"forming an impression of each other, based on the outward look or perceived character†, and gaining interest in them (Beebe, Susan and Mark, 292) Acquaintance: It was the next stage after the pre-interaction, where we â€Å"began to form a connection.† It entailed approaching my partner, passing greetings and enquiring basic information like names (292). Exploration: This is the next stage we went through, where we started â€Å"disclosing self information and taking more interests in engaging each other, at a more personal level† (Beebe, Susan and Mark, 292). Intimacy: The state at which the relationship â€Å"blossomed to intimacy and communication became more personalized, where we talked about anything and everything.† It was marked by indulgence in intimate activities (Beebe, Susan and Mark, 293). Turning point: The relationship then reached a casual turning point, which is â€Å"the event that moves the partners apart† (293), when I realized that my partner had lied to me about status, claiming to have been single, yet there already was a previous engagement. The relationship started at the awareness stage where we noticed each other and formed an impression based on the physical outlook. This was followed by the acquaintance stage where we embarked on knowing each other more personally. Then followed the exploration stage, where we self-disclosed information to each other, and then jumped to the intensification and intimacy stages, both of which occurred simultaneously and the intimacy stage overshadowed the intensification stage through personalized communication and discussing anything and everything. The relationship then entered the stagnation stage, after realizing that my partner had lied to me, and eventually separation occurred, where the personal interaction was terminated completely. Interpersonal relationships are formed through a process that entails different stages, where one stage leads to the other.

History of and Development of Apple

History of and Development of Apple History of Apples success Apple was founded in 1976, by Steve Jobs, Steve Wozniack and Ronald Wayne. These three young men at this time, decided to produce and sell a computer. As Apple was growing continuously, the company searched for some managers to help with the expansion. During the next couple of years, Apple hired new people for the most important positions, such as CEO. In 1984, the moment was finally there, Apple introduced there first computer to the world, the Macintosh. This computer was very special, because it was the first small computer with a graphical user interface. At the end of 1984, there was a big decrease in sales for Apple and deterioration in Jobs working relationship with the CEO of Apple. In May 1985, there followed a lot of struggles within company of Apple and Sculley relieved Steve Jobs of his duties as head of the Macintosh division. The founder of Apple was fired of his own company. Steve Jobs moved on and founded another computer company, called NeXT Computer. The NeXT Company was known of its technical strengths and their development system. All years Steve Jobs was working at NeXT with the philosophy of perfection, as showed by things like the NeXTcube interpersonal computer. In 1993, Jobs introduced a new development in software, with the release of NeXTSTEP Intel. During the period of NeXT computers, Jobs bought Pixar, a company focused on the high-end graphics. After a few years of struggling with sales, NeXT decided to contract with Disney. During their period with Disney, they started to produce numerous of computer-animated movies and Disney co-financed and distributed it. At the end of the 20th century, Apple decided to buy NeXT. This means that Steve Jobs returned to Apple. In the next couple of years, Steve Jobs changed a lot within the company, because there were too many employees working and introduced new projects. Steve Jobs was back in business for Apple. From this point, the success of Apple started with the introduction of Mac OS X and the iMac. (Guha, 2005) The last ten years Over the last ten years, Apple is doing something different than most IT companies in the world. Apple keeps it simple with its product line. If you are going to compare the products Apple offers and the products Microsoft or Sony are offering, you will notice that Apple only has 4 iPods, one cell phone, three notebooks and three desktop computers. If you take a look at Sony, you will see that they offer us a wide variety of the same kind of products. The same is happening with many other companies, such as HP, TomTom, Garmin and Dell. Within those last ten years, you can see that Apple is finding niche markets and try to fill the gabs in these markets. Since Steve Jobs returned to Apple, it has changed a lot. Steve reviewed all product lines and changed it into distinct segments. Every Apple product has a different destination, because an iMac is available for all-in-one solutions and the Mac Pro is for the professional buyer. These are just examples of two of Apples products, but it is exactly the same with the other products, such as the iPod or Notebooks. If you go into more detail about the simple product lines Apple uses, we will find that the company Garmin produces approximately 82 GPS systems that can be used in a car or carried in your hand. From all those 82 designs, there are no big differences between all models, but the price different is huge. Compare this with the Apple strategy; you can conclude that Apple will make only one or two different GPS systems, because Apple will use all their technology they have into one or two models, instead of 82. This strategy counts for a higher profit, because Apple does not waste a lot of money on all kind of different designs with slightly different specifications. If we have a look at the cell phone industry and we have a look at Samsung, we will discover that Samsung offers plenty of different models on their website. Apple produces only one cell phone and upgrades this phone every year with better technology, instead of making 20 different models. To conclude this, customers hate to choose between many different products with the same specifications. Imagine that you are at a random TV store and see all the different LCD or Plasma TVs. Many people will say they like to have many choices, but on the other hand they hate it. That is something Apple took into account and only produces one or two models of the same product of top-notch quality that are easily available. Furthermore, everybody knows Apple for more than five years now and Apple is known as the company with fantastic quality and easy accessibility. All the advertising and promotions Apple did in the last ten years worked, because the iPhone which you can buy at Best Buy, does not require a salesman to sell this phone. The brand sells itself. (Asay, 2010) Over the last five to ten years, Apple had an enormous growth explosion. As you can see in Figure 3, Apple had a slow growth up to 2005, but after that they started introducing new technology, which gave Apple its growth explosion. The findings of this explosion are shown in Figure 3. Product differences between Apple and other companies Apple is a company that started with computers; this is still their main market. If we have a look at the differences between Apple computers and other PCs, we can conclude that there are big differences. The biggest difference between the two is the way both parties think about processes and philosophies. According to many people, after using a Mac, they say: Macs think like I do and PCs dont. Although the operating systems of PC and Mac are kind of similar to each other, the Mac requires less clicking, less menus and it is working as smooth as people expect them to. If we move on to the other products Apple offers, the iPhones, we will notice a lot of differences compared to other mobile phones. If we are going to compare the iPhone with other mobile phones, you need to compare it with the Androids in first place, because these phones are Apples competition at the moment. The first thing we will notice is the operating systems within the phone, because Apple uses iOS Mac systems and Androids is mostly based on Google. If you are using the iPhone with all the features Apple gives you, you will never notice the differences, but Apple does not support Adobe Flash, which allows you to view Flash Videos and Flash Games. Androids have a better open system, because if you want to download an application and this application is not in Googles official Android Market, you can still download it and run it properly. If we have a look at the Apple applications, you can only use the applications giving to you via the AppStore. This brings us to our next poin t, because security is really important using these expensive phones. The problem with Android is that one in five applications have security holes, which makes the phone less safe and changes of viruses or any other inconvenient error. That is what makes the iPhone the safest phone around at the moment, because they have a closed system, which allows you only to download within the AppStore. Furthermore, we can compare the interfaces of both phones. Apple is doing a great job using a very easy but fantastic interface. If you like to use the iOS interface, life is great, because it works smooth and quick. On the other hand, if you prefer to use widgets and see what other interfaces look like, the Androids are the way to go. (Dotree, 2010)

computer architecture :: essays papers

computer architecture Computer architecture covers the design of system software, such as the operating system (the program that controls the computer), as well as referring to the combination of hardware and basic software that links the machines on a computer network. Computer architecture refers to an entire structure and to the details needed to make it functional. Thus, computer architecture covers computer systems, microprocessors, circuits, and system programs. Typically the term does not refer to application programs, such as spreadsheets or word processing, which are required to perform a task but not to make the system run. In designing a computer system, architects consider five major elements that make up the system's hardware: the arithmetic/logic unit, control unit, memory, input, and output. The arithmetic/logic unit performs arithmetic and compares numerical values. The control unit directs the operation of the computer by taking the user instructions and transforming them into electrical signals that the computer's circuitry can understand. The combination of the arithmetic/logic unit and the control unit is called the central processing unit (CPU). The memory stores instructions and data. The input and output sections allow the computer to receive and send data, respectively. Different hardware architectures are required because of the specialized needs of systems and users. One user may need a system to display graphics extremely fast, while another system may have to be optimized for searching a database or conserving battery power in a laptop computer. In addition to the hardware design, the architects must consider what software programs will operate the system. Software, such as programming languages and operating systems, makes the details of the hardware architecture invisible to the user. For example, computers that use the C programming language or a UNIX operating system may appear the same from the user's viewpoint, although they use different hardware architectures. When a computer carries out an instruction, it proceeds through five steps. First, the control unit retrieves the instruction from memory—for example, an instruction to add two numbers. Second, the control unit decodes the instructions into electronic signals that control the computer. Third, the control unit fetches the data (the two numbers). Fourth, the arithmetic/logic unit performs the specific operation (the addition of the two numbers). Fifth, the control unit saves the result (the sum of the two numbers). Early computers used only simple instructions because the cost of electronics capable of carrying out complex instructions was high. As this cost decreased in the 1960s, more complicated instructions became possible. Complex instructions can save time because they make it unnecessary for the computer to retrieve additional instructions. For example, if seven operations are combined in one instruction, then six of
