Fossil Fuel emission affect oceans in several way, as it increases carbon dioxide in it, thus acidifies it, and as organisms trap this gas, their carbonate (on their body) decreases

In short, Your Answer would be Option D

Hope this helps!

Answer from: kawtharALSAMARY

Option (D).

Explanation:

The burning of fossil fuels emits large amount of carbon dioxide in the environment. The increase in the concentration of carbon dioxide also effects the life of ocean.

The pH level of ocean decreases due to the formation of H+ ions in the oceans as the carbon dioxide reacts with water and form carbonate ions. The carbonate concentration in the ocean decreases. The carbon dioxide is present in large amount and its absorption increases in the ocean.

Thus, the correct answer is Option 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.
