I would go with B) Chaparral because with C) its in the name grasslands and trees mostly grown near grass and if u look in this picture on the left, that's grasslands and most of trees grow there and if u look in the middle that's a taiga and lots of trees grow there as well but in the last picture on the right u can rarely find trees there, now some trees can be there, but mostly none will be there due to the weather or environment . Hope this helps.

Answer from: lori90

I would say D, for both B and C.
Taiga biomes often have plenty of trees, so A is obviously no the answer.

Chaparral biomes have very few trees, so B would fit into the answer;
However, grassland biomes are covered mostly by grass. They are prone to fires, preventing too many trees from growing. Due to this knowledge, I can draw the conclusion that the answer B and C will work, meaning the answer is D.

Answer from: Quest

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.

Answer from: Quest

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.
