Without genetic variation, a population cannot evolve in response to changing environmental variables and, as a result, may face an increased risk of extinction. For example, if a population is exposed to a new disease, selection will act on genes for resistance to the disease if they exist in the population.
<u>Answer:</u>
<em>Environmental changes bring changes in the biodiversity too.
</em>
<u>Explanation:</u>
<em>Global temperature </em>change caused by various factors is an example of environmental change. When the temperature changes the <em>flowering pattern of plants and trees</em> are found to change. Many trees bloom at seasons different from their <em>actual blooming season.</em>
When temperature of aquatic environment changes it poses threat to already existing aquatic life. <em>Cold water organisms</em> die off when they become unable to adapt to the temperature change.
The<em> aquatic environment </em>will then be dominated by warm water aquatic organisms. Changes in salinity, precipitation, soil nutrient content etc causes various changes in the <em>flora and fauna of a region.

So i believe C is the correct answer :)
Answer:
organelles
Explanation:
Cells also contain the body's hereditary material and can make copies of themselves. Cells have many parts, each with a different function. Some of these parts, called organelles, are specialized structures that perform certain tasks within the cell.
Answer:
Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. ... This results in a net gain of two ATP molecules. Life first evolved in the absence of oxygen, and glycolysis does not require oxygen.
