Colorado has a vast population of lodgepole pines. A population of lodgepole pines has been killed in a section of the forest. What is a possible limiting factor of that population? devastation by the pine bark beetle Colorado’s long history of acidic soils genetic variability shallow root system

the correct answer is:

a population changes in response to a change in the environment.

a- multicellular

b-eukaryotic

c-no cell wall

d-heterotrophic

e-autotrophic

the fossil record provides evidence of a common ancestor to many species.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
