Q: Q: What are electromagnetic waves with the longest wavelengths called? Read this paragraph and choose the correct option from the provided answers: Electromagnetic waves on the left side of the Figure above are called radio waves. Radio waves are electromagnetic waves with the longest wavelengths. They may have wavelengths longer than a soccer field. They are also the electromagnetic waves with the lowest frequencies. With their low frequencies, they have the least energy of all electromagnetic waves. Nonetheless, radio waves are very useful. They are used for radio and television broadcasts and many other purposes. You can learn more about radio waves, including how they were discovered, at this URL: http://www. youtube. com/watch?v=al7sFP4C2TY . Choices: - channel waves - sound waves - infrared waves - radio waves A:
A: radio waves

Q: Q: What is the method of evolution by which advantageous heritable traits become more common over generations? Read this paragraph and choose the correct option from the provided answers: The theory of evolution by natural selection was proposed at about the same time by both Charles Darwin and Alfred Russel Wallace, shown in Figure below , and was set out in detail in Darwin's 1859 book On the Origin of Species . Natural selection is a process that causes heritable traits that are helpful for survival and reproduction to become more common, and harmful traits, or traits that are not helpful or advantageous for survival to become more rare in a population of organisms. This occurs because organisms with advantageous traits are more "fit" to survive in a particular environment and have "adapted" to the conditions of that environment. These individuals will have greater reproductive success than organisms less fit for survival in the environment. This will lead to an increase in the number of organisms with the advantageous trait(s) over time. Over many generations, adaptations occur through a combination of successive, small, random changes in traits, and natural selection of those variants best-suited for their environment. Natural selection is one of the cornerstones of modern biology. Choices: - artificial selection - same selection - flow selection - natural selection A:
A: natural selection

Q: Q: What are the two types of endoplasmic reticulum? Read this paragraph and choose the correct option from the provided answers: There are two types of endoplasmic reticulum. They are called rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER). Both types are shown in Figure below . Choices: - thick & smooth - rough & thin - rough & thick - rough & smooth A:
A: rough & smooth
