Scientists agree that increased concentrations of carbon dioxide in Earth's atmosphere have caused global temperatures to rise over time.
Many species can only survive within a certain temperature range. For this reason, species that are unable to adapt to rising temperatures
may eventually become extinct.
A solution designed to preserve Earth's biodiversity could include
A.
supporting natural and artificial processes that extract carbon dioxide from the air.
B.
placing critically endangered species in climate-controlled environments.
C.
reducing the total amount of carbon dioxide entering the atmosphere.
n
all of these

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.

explanation:

c is the answer to this question. altitude affects the weather because air molecules evaporate.
