Answer:

The correct answer is option - B.

Explanation:

Clams are the bivalve mollusks that are classified as a consumer or the filter feeder as they internalize the particles and the suspended nutrients and matter in the water to carry out energy and nutrients for them.

These are known as a consumer due to their bivalve body and get its specific structure which is using gills to filter the food or nutrients particle. This makes the clams unique as some other bivalves organisms.

Thus, the correct answer is option - B.

Tasya [4]

Answer: The correct answer is -

D) A ---> B + C + energy.

Explanation:

Catabolic reactions can be described as one of the two types of metabolic reaction (other being anabolic) which occur within cell when complex organic molecules are broken down to form simpler, smaller molecules.

For example - Respiration, which involves glucose breakdown in order to form carbon dioxide and water. Generally they are type of hydrolysis reactions, which include water to break bonds present in complex molecules.

Large amount of energy is also released during these reactions.

Thus, option D) shows catabolic reaction.

n200080 [17]

Answer:

The pig's genotype is Tt

Explanation:

As mentioned in the question that curly hair allele T is dominant over straight tail allele t.

A heterozygous organism is that in which both alleles for a trait are different. Since Curly hair allele T is dominant over straight tail t, it means that the pig with curly tail and heterozygous genotype will definitely have a genotype of Tt.

Hope it helps! :)
