kolezko [41]

Answer:

B. polyphyletic group

Explanation:

Polyphyletic group is a taxon which comprises of organisms which are unrelated and do not share a recent or immediate common ancestor. Polyphyletic group is often used to refer to a group of organisms with similar characteristics called homoplasies, but not inherited from  a common ancestor. This means that the organisms are of multiple origins irrespective of the traits that make them similar.

Therefore, from the question, because we do not consider ourselves fish, we would describe the group "fish" as polyphyletic.

LiRa [457]

Answer:

Option-C

Explanation:

A pulse-chase experiment which is used to study the cellular process taking place in the cells. This uses the labelled molecule which is incorporated into the cellular pathway and then the unlabeled molecules are used over time to determine how much time is required by the unlabeled molecule to replace the labelled molecule.

In the given question, the pancreatic cell which secretes the digestive enzyme known as the acinar cell is labelled with the leucine and then used unlabeled leucine.

When observed after three hours, the black spots will appear on the exterior of the cell as the protein has been synthesised by the ER and now has been secreted from the cell.

Thus, Option-C is the correct answer.
