At what stage of erythropoiesis is the developing red blood cell released into the circulation

It takes place in 8 stages where the first seven steps takes place within the bone marrow and after the 7th step the red blood cell is released into the blood stream as reticulocyte which then matures to erythrocyte after 1-2 days.

Nataly_w [17]

The question is incomplete as it does not have the option which are:

  • primates A and B are more closely related to each other than either is to primate C.
  • all three primates appeared on Earth at about the same time.
  • either primate A or primate B must be a direct ancestor of primate C.
  • primate C must have been the ancestor of both primate A and primate B.

Answer:

Primates A and B are more closely related to each other than either is to primate C.

Explanation:

In the given question, on the basis of the given information, it can be predicted that the Primate A and B are more closely related to C as the DNA sequences of these two primates are almost similar. The similarity of the sequence suggests that these primates have descended or diverged from a common ancestor.

The DNA sequence of C is different from both A and B which shows that both A and B are different from the C.

Thus, the selected option is the correct answer.
