An alternation of generations for plants include a haploid gametophyte and a diploid sporophyte.
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.

The epididymis region of the testis do they remain.
<h3>What about epididymis?</h3>
- Each testis has a little, tightly coiled tube linked to it (the male sex glands that produce sperm).
- Male reproductive cells known as sperm travel from the testicles into the epididymis, where they mature and are then stored.
- The epididymis' most obvious job is to move sperm from the rete testes to the vas deferens.
- The immature sperm from the testis is received by the tortuously coiled epididymis, which stores it for several days.
- Sperm is forcibly discharged into the deferent duct during ejaculation from the epididymis' tail.
- Sperm is transported from the testes and stored in the long, coiled epididymis.
- It is seen as a curving structure on each testis' posterior (rear) edge. There are three parts to it.
