A . Sex cell
Somatic cells are body cells which are identical to the cell it came from. Sex cells are cell that are different from the parent cell and have genetic diversity
The mechanism in a cell's connected section of the membrane that detects chemical signals is i.e. structure labelled B in the diagram. Thus, the correct option is D.
<h3>
What are receptors?</h3>
Receptors, which are large proteins that can be found within or outside of cells, are the components of a cell that are in charge of identifying chemical signals.
Whereas plasma membrane junctions interact with surface proteins found inside cells during cell to cell signaling.
Thus, it follows that the structure designated B in the diagram is the one that serves as a chemical signal receptor.

Sperms (Pollen is technically a male gametophyte, meaning an organism that makes “gametes”, which in this case is sperm.).
Answer:
A change in the number of single chromosomes without a change in the overall number of genes is called "Dysploidy" and the duplication of a whole genome is called "Polyploidy"
Explanation:
Dysploidy is the change in the chromosome base number produced by chromosomal rearrangements that occurs without loss of genetic information. On the other hand, polyploidy refers to the condition of having more than two complete sets of chromosomes
