An island frog population is made up of two color phenotypes, green and brown, caused by different coloration alleles. The frequency of coloration alleles is shown in the Original Population box in the diagram. Because of changes in the environment, green frogs become more visible to predators and brown frogs are better camouflaged. Part A
How many green and brown colored symbols should go into the New Population box to predict the frequency of frog coloration alleles due to the changes in the environment.

Part B

Select the evolutionary mechanism that would cause this change in allele frequency.

There may be more than one correct answer.
A
Founder effect
B
Natural selection
C
S3xual selection

Which statements best describe the differences or similarities between a comparative investigation and an experimental investigation? check all that apply. experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship. comparative investigations are often impractical and unrealistic, while experimental investigations are the most practical and realistic kinds of investigations. comparative investigations allow for the use of a wide range of variables but do not have a control group, while experimental investigations involve variables that can be controlled. both experimental investigations and comparative investigations are designed to answer scientific questions. both experimental investigations and comparative investigations focus on making observations rather than collecting new data.
