Given what we know, we can confirm that the correct option is D, which states that "<em><u>They are used by living things as the </u></em><em><u>main source </u></em><em><u>of </u></em><em><u>energy</u></em>."
<h3>What are carbohydrates?</h3>
- They are the primary source of energy for most cells.
- They are what we refer to as sugars.
- The main example of this is glucose.
- They are formed by monomers called monosaccharides.
Therefore, we can confirm that since carbohydrates are what we refer to as sugars, which include molecules like glucose and this is the main source of energy for most cells, option D is the correct choice.

Answer:
The correct option is A
Countercurrent multiplication is the process whereby energy is used to generate an osmotic gradient in which water is reabsorbed from the tubular fluid to produced concentrated urine.
Explanation:
Countercurrent multiplication moves sodium chloride from tubular fluid into interstitial space deep within the kidneys. The concurrent multiplication process build up osmotic gradient interstitial fluid in a single effect. Here, sodium chloride is driven by active transport out of the tubular fluid in the thick ascending limb into the interstitial fluid, which becomes hyperosmotic. This result to water moving passively down its concentration gradient out of the tubular fluid in the descending limb into the interstitial space to a point where it attains a state of equilibrium.
Therefore,the correct option is A, where the ions leaves the ascending limb to make water comes out of descending limb.
the three functions of mitosis are Asexual Reproduction, growth, and tissue repair.
<h2>Phenotype probability</h2>
Explanation:
- In the given question,let say A is dominant allele and a is recessive allele
- Homozygous recessive parent(having both alleles recessive) will be denoted by aa genotype whereas heterozygous parent(one allele is dominant while other is recessive) will be denoted by Aa
- When a cross is made between both the parents then the probability of offspring having the recessive phenotype will be 1/2 or we can say 50%
The correct answer is D.Bioaccumulation
This means accumulation of biological material which is never done by beneficial bacteria.
