< is a symbol of less than and when you multiply 3 by x the answer is 3x so 8<3x
D. It allows a variety of substances to dissolve in and around cells.
Explanation:
The shell of hydration is important to life because it allows a broad range of substances to dissolve in and around the cells.
- The shell of hydration allow for water to dissolve a wide range of substances and disperse them uniformly in it.
- Water serves a solvent capable of dissolving a wide range of substances because it forms a hydration shell round them.
- This allow for materials to be in solution around the cell.
- Diffusion and osmosis can readily now take place.

Answer:
Genes coding for proteins involved in chiasma formation.
Explanation:
Chiasma is the connecting link between two non sister chromatids from homologous chromosomes. At chiasma chromosomal crossover takes place in which the genetic material is exchanged between the chromatids. During meiosis aneuploidy occurs if chiasma is absent or impaired due to a mutation in genes encoding for proteins involved in chiasma formation.
Aneuploidy is characterised by presence of abnormal number of chromosomes in cells. They can be 45 or 47 in number apart from the usual 46. Due to impaired chiasma, chromosome pair fails to separate and is passed on to the egg or sperm as it is hence there is one gamete with an extra chromosome and one gamete with a less chromosome. Aneuploidy can result in many genetic disorders like three copies of chromosome 21 can result in Down syndrome.
