There is a population of birds that differ in feather color, and in diet. The green feathered birds eat fish, while the red feather birds eat insects a drought. His habitats of this population of the child has no effect on the insect population, but it dries up the pons and the fish population declines. The main selective pressure for the birds in the scenario is:
A. The insect population
B. The fish population.
C. The red feathers.
D. The green feathers.
B. The fish population.
There is a population of birds that differ in feather color, and in diet of the green feathered birds, eat fish while the web for the birds eat insects A.CHAL hits the habitat of this population. The job has no effect on the insect population, but it dries up the pounds and the fish population decline in the above example through the pie process of nature selection. We will expect that
A. Green feathered birds will become more common
B. Red feathered birds will become more common
C. Green feathered birds will go extinct
D. Redfeather birds will become extinct
A. Green feathered birds will become more common.
Based on the theory of natural selection, what what the next generation of moth look like?
A. Black.
B. White
C. White and black.
D. They will go extinct.
C. White and black.
A population of chickens is introduced to the environment that has very hot summers and extremely cold winters every year some chickens die due to extreme temperatures. The chickens have a range of small sizes: small, medium and large.
Every winter, more of the small chickens, die than the others. every summer, more of the large chickens, die than the others.
When the population was introduced to the new environment, there were equal numbers of each size. after several years, what will the frequency of chicken sizes be is the population?
A. There will be an equal number of chickens of each size.
B. There will be more large chickens
C. There will be more medium chickens.
D. There will be more small chickens
