The cell is in METAPHASE PHASE OF MEIOSIS. At this phase, the pairs of homologous chromosomes moves to the cell equator. These pairs of homologous chromosomes will be separated in anaphase I. The number of chromosomes remains constant until the first cell division is completed, then the chromosomes will be divided into two daughter cells.
Answer:
D
Explanation:
Hormones are bigger than the cell pores hence cannot pass through the cell membrane to influence biochemical processes. Therefore, hormones (such as glucagon and insulin) bind onto receptors on the cell membrane, then transmembrane proteins, such as the G-protein, change conformation activating the secondary messengers inside of the cell. Cyclic- AMP is a major secondary messenger significant in activating protein kinases.

Plz mark me as brainist
<em>yes it is right because if we take example of viruses and germs .. new germs and viruses are much modified as compared to old ages because they adopted the ways they can escape from the immunity.. they have an adoption to transmit their DNA material ,also they can take protein coat of host because of which host's immunity cells cannot recognize germs as foriegn particle..and in this way germs and viruses remain for a long time in body due to the adoptations according to age and environment..</em>
I need more details sorry
