Answer the following question given this paragraph: Figure 8.12 The colors of visible light do not carry the same amount of energy. Violet has the shortest wavelength and therefore carries the most energy, whereas red has the longest wavelength and carries the least amount of energy. (credit: modification of work by NASA). Q: Violet and red are two types of what kind of light? Choices: - infrared - ultraviolet - radioactive - visible A:
visible

Ques: Answer the following question given this paragraph: Common foodborne viruses include norovirus and hepatitis A virus. Norovirus, which causes inflammation of the stomach and intestines, has been a recent issue on cruise ships, infecting hundreds of passengers and crew on certain voyages. Hepatitis A causes inflammation of the liver, which is treated with rest and diet changes. Parasites are tiny organisms that live inside another organism. Giardia is a parasite spread through water contaminated with the stools of people or animals who are infected. Food preparers who are infected with parasites can also contaminate food if they do not thoroughly wash their hands after using the bathroom and before handling food. Trichinella is a type of roundworm parasite. People may be infected with this parasite by consuming raw or undercooked pork or wild game. Q: Norovirus causes the inflammation of the stomach and what else? Choices: - muscles - liver - lungs - intestines A:
Ans: intestines

Answer the following question given this paragraph: Pearls are highly valued as gemstones. Most gemstones come from the Earth, but pearls come from living things. They are created by mollusks, such as oysters. Q: What gems are created by mollusks, such as oysters? Choices: - crystals - turquoise - diamonds - pearls A:
(A).
pearls
Ques:Answer the following question given this paragraph: Biology has only a few over arching theories. One of these, the Cell Theory of Life, explains the historic continuity of organisms, while the Theory of Evolution by Natural Selection (and other processes), explains both the diversity of organisms and how populations of organisms change over time. Finally, the Physicochemical Theory of Life explains how it is that organisms can display their remarkable properties without violating the laws that govern all physical and chemical systems.40 What is life, exactly? Clearly, if we are going to talk about biology, and organisms and cells and such, we have to define exactly what we mean by life. This raises a problem peculiar to biology as a science. We cannot define life generically because we know of only one type of life. We do not know whether this type of life is the only type of life possible or whether radically different forms of life exist elsewhere in the universe or even on Earth, in as yet to be recognized forms. While you might think that we know of many different types of life, from mushrooms to whales, from humans to the bacterial communities growing on the surfaces of our teeth (that is what dental plaque is, after all), we will discover that the closer we look the more these different "types of life" are in fact all versions of a common underlying motif, they represent versions of a single type of life. Based on their common chemistry, molecular composition, cellular structure, and the way that they encode, read, and use hereditary information in the form of molecules of deoxyribonucleic acid (DNA), all topics we will consider in depth later on, there is no reasonable doubt that all organisms are related, they are descended from a common ancestor. We cannot currently answer the question of whether the origin of life is a simple, likely, and predictable event given the conditions that existed on the Earth when life first arose, or whether it is an extremely rare and unlikely event. In the absence of empirical data, one can question whether scientists... Q: The theory of evolution by what (and other processes) explains both the diversity of organisms and how populations of organisms change over time? Choices: - natural evolution - characteristic selection - genocide - natural selection A:

Ans:natural selection
Answer the following question given this paragraph: The two ovaries are small, egg-shaped organs that lie on either side of the uterus. They produce eggs and secrete estrogen. Each egg is located inside a structure called a follicle . Cells in the follicle protect the egg and help it mature. Q: The small, egg-shaped organs that lie on either side of the uterus are called? Choices: - lungs - glands - kidneys - ovaries A:
ovaries
