Biology

Rasek [7]3 years ago
8 0

Answer:

Haploid number of chromosomes.

Explanation:

Before fusion of sex cells i. e. sperm cells and egg cells, there are half number of chromosome present in each sec cell because in the sex cells meiosis occurs. Meiosis is a type of cell division in which a single parent cell divides into four daughter cells having haploid chromosome i. e. half number of chromosomes in each daughter cell. So when these sex cells fuse together, they form a diploid organism.

The process occurring at the sensory receptors that converts physical energy into coded neural activity that the nervous system
Anika [276]

Answer:

Sensory transduction

Explanation:

The sensory process involves many steps to send the signals from the receptor to the brain.

In this, the step that is involved in the conversion of the physical energy into the electrical signal at the sensory receptor  (in the given case mechanoreceptors) is known as the Sensory transduction.

When the mechanoreceptors get stimulus by the physical force, it opens the mechanical gate of the dendrites which allows the influx of the positive ions. The influx of the positive ions causes depolarization of the membrane which initiates the action potential which is then transmitted to the brain.

Thus,  Sensory transduction is the correct answer.
