Stabilizing selection is the most common form of natural selection. it eliminates any extreme expression of a trait in a population of organisms when the average expression leads to a higher rate of survival. stabilizing selection tends to a) decrease genetic sameness. b) decrease genetic diversity. c) increase the frequency of a rare allele. d) increase the frequency of two rare alleles.

Use this diagram of an animal cell to answer the question. where does the first stage of cellular respiration occur? w x y z

Read the following scenario to answer the following question. in some zoos, rare crosses between a male lion and a female tiger have produced hybrid offspring called "ligers." male ligers are sterile but some female ligers are fertile. in the wild, lion and tiger ranges do not naturally overlap, making such a cross unlikely. furthermore, the solitary behavior of tigers and the social organizations of lions create behavioral differences. applying the biological species concept, the sterility of ligers reveals that a. lions are probably a subspecies of tigers b. tigers and lions are the same species c. a new species called "ligers" is forming d. tigers and lions are separate species

Plz ! a frog has a genetic mutation in skin cells that causes part of its skin to turn orange the frog will not pass this genetic mutation onto its offspring because, a. the offspring will inherit skin cells from the other parent. b. mutated skin cells cannot divide and produce daughter skin cells. c. skin cells do not contribute genetic material to sex cells. d. parents do not contribute genetic material to their offspring.
