Unit 5 Evidence of Evolution QUIZ

Peppered moths can have either a light wing color or a dark wing color. A scientist studied populations of both light and dark peppered moths over a 10-year period. A graph of the data he collected is shown. Based on the graph, which is the BEST conclusion to make about changes in the moth populations by the end of the study period? (HS-LS4-4)

• A disease has affected only the dark-winged peppered moth.
• At present, wing color is not a factor in the success of peppered moths.
• A new food source has become available only to the light-winged peppered moth.
• At present, dark-winged peppered moths are being naturally selected for survival.

The jaw of the California Kingsnake can unhinge, allowing it to open its mouth to a size greater than that of its head. This structural adaptation spread among the California Kingsnake population because it gave snakes with the trait which survival advantage? (HS-LS 4-2)

• ability to conform to tight spaces
• greater efficiency in oxygen absorption
• capability to consume prey of variable size
• better vision due to eye positioning on head

• climate change
• natural selection
• asexual reproduction

Diversity among members of a species is important because diversity___________. (HS-LS4-2)

• ensures high levels of competition.
• increases the available ecosystem resources.
• ensures the variety of reproductive methods for a species.
• increases the chances of survival under changing conditions.

The praying mantis is well camouflaged in its natural habitat. What is a benefit of this adaptation? (HS-LS4-2)

• It allows absorption of chlorophyll from plants.
• It offers protection from icy weather conditions.
• It increases the chances of survival from predation.
• It reduces the mutation rate of favorable genes.

If the climate were to change in an environment it is more likely that some individuals within a population will survive if: (HS-LS4-4)

• The individuals stop reproducing
• The individuals are genetically identical
• There is genetic variation within the populations
• The individual reproduce asexually

Using the image below answer the following question, Giraffes developed longer necks overtime, how does this adaptation help the population size? (HS-LS4-4)

• Giraffes with long necks were able to eat and this helped increase the population size.
• The development of the neck did not change the population size
• The giraffes stopped reproducing so the population decrease
• The giraffes with short necks still reproduce and exist.
