Answers

Answer 1

Answer: When a cell shows formation of a contractile ring just prior to cytoplasmic division, this cell is recognized as a human fetal cell. The correct answer is option C.

In plant cells, it is a cell plate that is formed and not a contractile ring.

What is fruit fly?

Fruit fly is known as Drosophila melanogaster. It is a well-known fruit fly. It has about four chromosomal pairs: one which determines the sex and the rest three are the autosomal chromosomes. In which, each chromosome has two arms, which are referred to as the left and the right.

Drosophila melanogaster is a fruit fly, in which XX, XXY, and XXYY flies are females, while XY and XO flies are males. Flies which are unable to survive with more than two copies of an X chromosome because of the mechanism that they use for dosage compensation turn out to be male flies and those which contain two or more copies of X-chromosome turns out to be female fly.
