Unit One: Animal Structures and Functions‚ Answers to Review Questions Respiratory System 1. Indicate the importance of gas exchange in all living organisms. Respiration is gas exchange (Oxygen and Carbon Dioxide) with the external environment. All living things respire. Gas exchange is important so that cellular respiration can take place and energy can be made for the cells. 2. Distinguish among the terms cellular respiration‚ external respiration and internal respiration

Are We Evolution? Evolution is the thought process of different kind of organisms and how they came about. First Coyne begins to describe his version of evolution‚ he believes its nature‚ that’s plants and animals were perfectly created or designed for living their lives. Throughout the first page Coyne compares evolution to Willam Paley’s idea of a watch maker‚ he says if you see a watch laying on the floor you automatically know it’s a work of a watchmaker. In my opinion it compliments evolution

diversity. With the rainforests being some of the oldest biomes on Earth‚ species have had the most time to diversify. The size of the rainforest provides opportunity for geographic separation for groups within a species which may result in speciation‚ and a predictable climate allows for species to specialize in food sources that are available during the year. Unfortunately the diversity of the African rainforest is threatened due to logging‚ hunting‚ and poor

Look at a domestic dog and compare it to the mighty wolf. Are there any similarities or differences? Domestic dogs‚ that live within our human world‚ are comprised of some of the same features gray wolves contain. Through natural selection and speciation‚ these two species are configured by physical differences. Most dogs are smaller in size than wolves. There is also a difference in the head structure of both species. Wolves have a longer snout and dogs have steeper foreheads‚ along with a wider

the roots of all our evolutionary thinking go back to Darwin. Darwin’s theory of evolution is a bundle of theories. And in order to fully understand Darwin’s theory of evolution we should distinguish its different components. Which are evolution‚ speciation‚ common ancestry‚ natural selection. A little explanation of these points or theories is as following: Evolution as Such This simply means that this world was not as always as in its current form.

Nowadays‚ climate change is one of the most natural events that has occurred throughout the world. It has led to a strong effect on many animals‚ by becoming a main decision of the developments of speciation or a widespread extinction. In fact‚ many reptiles are highly susceptible to the changed temperatures due to their physiological features which need to respond the surrounding environment to remain equally the body temperature. Additionally‚ there are many kinds of snakes‚ lizards‚ crocodilians

What is the difference between the fundamental niche and the realized niche? 7. Study Figure 54.5‚ and then explain what is meant by character displacement. (To do this‚ you will have to learn or review the difference between sympatric populations and allopatric populations. You will find this information in Chapter 24.) 8. Predation is a term that you probably already know. Can you give examples of some predator-prey combinations as listed below? Predator Prey Animal Animal
