Q: Somatic, autonomic, and enteric structures are part of what system? Read this paragraph and choose the correct option from the provided answers: Figure 12.6 Somatic, Autonomic, and Enteric Structures of the Nervous System Somatic structures include the spinal nerves, both motor and sensory fibers, as well as the sensory ganglia (posterior root ganglia and cranial nerve ganglia). Autonomic structures are found in the nerves also, but include the sympathetic and parasympathetic ganglia. The enteric nervous system includes the nervous tissue within the organs of the digestive tract. Choices: - circulatory system - circulatory system - adrenal system - nervous system A:
nervous system

Q: Under which process do living things with beneficial traits produce more offspring? Read this paragraph and choose the correct option from the provided answers: The other idea is that evolution occurs by natural selection. Natural selection is the process in which living things with beneficial traits produce more offspring. As a result, their traits increase in the population over time. Choices: - migration - differentiation - evolution - natural selection A:
natural selection

Q: Q: A gene may have different versions called what? Read this paragraph and choose the correct option from the provided answers: Traits are controlled by genes on chromosomes. A gene may have different versions called alleles. Choices: - genomes - peptides - locus - alleles A:
A: alleles

Answer: kidneys

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:
**Answer**
natural selection

Q: What causes earthquakes at mid-ocean ridges to be small and shallow? Read this paragraph and choose the correct option from the provided answers: Earthquakes also occur at divergent plate boundaries. At mid-ocean ridges, these earthquakes tend to be small and shallow focus because the plates are thin, young, and hot. Earthquakes in the oceans are usually far from land, so they have little effect on peoples' lives. On land, where continents are rifting apart, earthquakes are larger and stronger. Choices: - plates are thin , young , and cold - plates are thick , young , and cold - plates are thick , old , and hot - plates are thin , young , and hot A:
plates are thin , young , and hot
