Paragraph about how genetic variation and environmental pressures can cause a change in population

Answers

Hmm.. good one. :)

1.) Genetics are what can create features or behaviors in animals or other living organisms. So this can cause a change in population because say one species of bird was born by two slightly different parents, now it has both genetics from both. This can be good or bad. Say the dad's genetics sucked but the mother's genetics were good. This bird might be better at surviving or better at being prey. 

Environmental Pressures: 1.) If rabbits die because of a disease, their predators will become hungry. The predators might go down in number too and die as well. If anything in nature goes wrong, it may affect a population to either increase or decrease.

Organisms with advantageous adaptations are more likely to survive and reproduce than organisms without the advantageous adaptations. This phenomena is known as natural selection.In order for natural selection to occur
A.) organisms within a population must have some genetic variation.
B.) there must be more male organisms than female organisms.
C.) all of the organisms within a population must be exactly the same.
D.) one population must become extinct so another can be created.

Answers

Inorder for natural selection to occur organisms within a population must havesome genetic variation. Naturalselection is when species learn to adapt to their environment. They could (1)differential reproduction, that is, not all organisms are able to reproduce totheir fullest capacity because nature cannot simply sustain it and (2) acquire genes,that is heredity. Certain characteristics of organisms tend to survive if itcontinues to strive. If it survives, this trait is passed down to the nextgenerations forgetting the other traits but only the one who could survive theenvironment. Therefore it is true that natural selection is when‘organisms inherit advantageous traits, and tend to reproduce more successfullythan other organisms’.

A. organisms within a population must have some genetic variation.
