Which of the following statements regarding natural selection is not true? It is a random process. A favorable trait in one environment is not always a favorable trait in a different environment. It is a mechanism by which evolution may occur. It occurs even if the frequency of the specific trait doesn't change over many generations.

6. Which of these conditions will lead to evolution by natural selection? a. Heavy metal pollution reduces reproductive success of all phenotypes of green algae in the pond. b. Variation among individuals is not genetic; instead it results from learned behavior or physiological environmental responses. c. Introduction of an exotic predator species results in one native prey phenotype evading predation while other phenotypes get eaten. d. Individuals of the population are clones (genetically identical). 7. Which one is used as...

Which of the following statements regarding the Hardy-Weinberg Equation is TRUE? Answers: It can only be used when allele and genotype frequencies remain constant across generations in a population It can only be used when allele and genotype frequencies change across generations in a population It has no assumptions It mathematically shows how recessive alleles in a population decrease over time It reveals when allele frequencies change over time in a population Assuming Hardy-Weinberg Equilibrium, what percentage of individuals in...

5. Which of the following statements is true about the theory of evolution? The focus of the theory of evolution is to explain the origins of life. According to the theory of evolution, life evolved entirely randomly. The focus of the theory of evolution is to explain how life diversified from the first living cells. According the theory of evolution, only the strongest and toughest can survive. 6. Which of the following best explains our current understanding of microevolution? Neither...

13. Indicate whether the following statements are true or false. If false, correct the statement so that it is true. a. A change in enthalpy for exothermic chemical reactions is negative. b. An endothermic reaction is one in which enthalpy is absorbed by the system from the surroundings. c. Condensation of water vapor is an example of an endothermic process. d. Heat, q, and enthalpy, AH, are state functions, meaning they depend on the path taken, and q = AH....

(2 points each) a) A change in primary structure always results in a change in tertiary structure. b) The largest force governing protein structure is the hydrophobic effect. c) Protein folding begins with the formation of tertiary structure. d) A heterodimer exhibits quaternary structure; a homodimer does not.

TRUE-FALSE-UNCERTAIN For each of the following claims, indicate whether it is true or false, or whether it could be either one, depending on circumstances. Then, explain why. Your grade will depend on your explanation. Try to make sure your explanation is not only correct but thorough. In particular, if a statement is false for more than one reason, discuss all those reasons (even though, logically, it takes just one contradiction to make the entire statement false). Doing this will prepare...
