Question 1: How would the genetic traits of a population change in response to an environmental pressure such as overfishing?
a) The amount of genetic variation in traits would remain the same. b) The genetic diversity of the population would increase. c) The genetic traits would not be affected by environmental factors. d) The genetic traits not selected by fishing would increase in the population.
Question 2: What role does intraspecies competition play in natural selection?
a) There is competition within a species for resources, and only some individuals will survive. b) There is competition within a species for resources, and only the single most fit individual will survive. c) There is competition between species for resources, and only one species will survive. d) There is competition between species for resources, and only one individual per species will survive.
Question 3: Which of the following would most likely lead to an adaptation?
a) A dangerous situation affects an individual. b) A species wants to move to a new environment. c) An individual reaches reproductive age. d) An inherited trait helps an organism survive and reproduce.
Question 4: Which of the following would be considered a benefit of overproduction?
a) The exponential growth of a population b) The survival of the fittest due to competition for resources c) The exchange of genetic material between populationsd) The change in an ecosystem due to the increased population
Question 5: Which type of change can be inherited?
a) An injury that results in a scar b) An increase in speed due to practice c) A genetic mutation d) A change in muscle mass due to exercise
