B) Diploid - Only Gametes are Haploid. Every other cells are somatic cells which are diploid. They contain 46 chromosomes rather than 23 that the haploid carry. Neurons and glial cells make up of the brain and that makes up the nervous tissue. Just remember Gametes (sex cells) are the only cells that are haploids.
Consuming excessive amounts of pure water creates hypotonic environment in the body fluid surrounding the cell.
<h3>
What is a hypotonic solution?</h3>
- A solution having lower osmotic pressure than the solution to which it is compared.
- It has lower amount of solute (high amount of solvent) compared to other solution separated by a semi-permeable membrane.
- After consuming excessive amounts of pure water, the body fluid becomes hypotonic, so water enters from body fluid to the cell resulting in the cell to swell or break.
