What is the main difference between c3 and c4 carbon fixation? a. in c3 carbon fixation, plant stomata are open during the day, while they are open at night for c4 carbon fixation. b. c3 processes take place throughout the leaf, while c4 processes take place in the inner cells. c. c3 carbon fixation is more common in areas with high light intensity than c4 carbon fixation. d. c3 processes are more efficient than c4 processes in high temperatures.

C3 carbon fixation is more common in areas with high light intensity than C4 carbon fixation.

The correct answer would be B.

I just did the quiz on edg. Hope this helps!

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.

a community that experiences major changes undergoes progress
