The medium ground finch is a bird common to the Galapagos Islands. The bird uses its beak to crush and eat seeds from plants. Small, soft seeds are easier for the ground finch to crush. However, the plants that produce small seeds do not grow well during seasons with low precipitation amounts. Instead, the medium ground finches with larger beak depths are better able to crush large seeds which are available during these dry seasons. Which statement is the most likely explanation for the relationship between beak depths and environmental factors?
Genetics determines medium ground finch beak depths and raifall has no effect on the birds
Rainfall has no effect on medium ground finch beak depths because seed production is abundant
Smaller beak depths are more beneficial during dry seasons since medium ground finches prefer small seeds
Larger beak depths give some medium ground finches a feeding advantage to consume larger seeds

How does the process of meiosis affect the genetic information of an offspring?
Meiosis creates mutations in an offspring to decrease the variety of genetic information being passed from both parents
Meiosis passes on the genetic information from only the mother to an offspring since the process of mitosis passes on genetic information from the father
Meiosis is a type of asexual reproduction that prevents genetic information from being altered when passed from parents to an offspring
Meiosis forms sperm and eggs, which unite during fertilization to determine the genetic information of an offspring
A factory located near a river experienced an accident, causing the release of hundreds of liters of chemicals into the river. Scientists investigating the accident found that young crayfish in the river near the factory had white coloring instead of their normal dark orange color. Which statement provides a likely cause for the scientists' observation?
The chemical made the crayfish sleep more than usual, giving them white coloring because they were not awake to produce their normal dark orange color
The chemical caused a mutation in the gene for color in the crayfish, resulting in proteins giving the next generation white coloring rather than their normal dark orange color
The chemical caused the young crayfish to eat extra proteins in the water, giving them a white color rather than their normal dark orange color
The chemical destroyed all the genes in the crayfish, causing them to have white coloring rather than their normal dark orange color

The graph below shows the various rates of running speed in a prey population. Which of the following statements supports the idea that genetic variation in a population increases the chance that some individuals will survive more than others?
The number of prey that run at a medium rate is highest, so over time there will be an overpopulation of prey that run an average rate of speed.
Because more prey run at an average rate, more average runners will survive to pass their traits on to offspring.
Slow prey will become faster out of a need to avoid predators and there will be fewer prey that run slowly in the next generation.
Over time prey that run faster than predators will survive, which will lead to an increase in the population of fast runners over time.
