1. Consider both of the following statements: 200 words Mutations are caused by selective pressure in the environment. The same mutation could be advantageous in some environments but deleterious in others. For each statement, is it true or false? Explain your reasoning. 2. Explain how the environment plays a role in changing the frequency of a mutant allele in a population.

Which of the following statements about mutations is true? Some regions of the genome are more likely to accumulate mutations than others. Environments encourage adaptive mutations to arise. Environmental factors cannot affect mutation rates. All conceivable mutations are equally likely to be present in a living individual.
Joanna Q.
True or False: Organisms intentionally induce mutations to occur in order to help them to adapt to their environment. True False What is one reason why many mutations may be deleterious (bad)? Select only ONE answer choice. Because the genetic code has redundancy built in. Because if a mutation changes the primary structure of a protein, the protein may no longer work. Most mutations are actually beneficial, not deleterious. Any change in the DNA sequence means that DNA no longer functions properly.

Write short paragraphs explaining each of the following statements: a. Natural selection chooses from among the individuals in a population those most suited to current environmental conditions. It does not guarantee survival under future conditions. b. Individuals do not evolve, but populations do. c. The organisms that exist today do so because their ancestors had traits that allowed them and their offspring to thrive. d. At the molecular level, evolution can take place by the replacement of one nucleotide by another. e. Evolution is said to have occurred within a population when measurable genetic changes are detected.
