Akimi4 [234]

Answer:

In reproductive or sexual cells

Explanation:

There are two principal types of cells in the organism: Somatic diploid cells (2n) that reproduce by the process of mitosis, and germ cells that are diploid reproductive cells in charge of gamete production. These germ cells suffer both mitosis (to form more sexual cells) and meiosis (giving place to haploid gametes: sperm and egg cells, through the gametogenesis process). Both somatic cells and germinal cells will end their cycle becoming two daughter cells with the same genetic dotation.

Gametes from each parent will merge in the process of fecundation, during which a new diploid cell called a zygote emerges through fertilization. The zygote is a complete cell from the structural point of view that suffers successive mitosis to form the new organism.

Any cell in the organism might suffer mutation.

  • If the mutation occurs in the somatic cells, it will produce a population of identical mutated cells in that organism. However, this mutation in these cells is not inheritable. By definition, mutations in somatic cells do not inherit because these cells do not produce progeny.
  • If the mutation occurs in the germinal line, in the germ cells, or the sexual cells, this <u>mutation will pass to the offspring</u>. The organism with mutated germinal cells might express a normal phenotype, but this mutation will be detected in the progeny.

joja [24]

Answer:

The correct answer is - B) Elysia Chlorotica grows when exposed to light in the absence of other food sources

Explanation:

If placing Elysia Chlorotica in presence of the food sources in the presence or absence of light it still grows as normal. However, if placing in the light in absence of the food sources it should not grow if it is not able to perform photosynthesis but it does which means there is a photosynthesis process also involve in the Elysia.

Photosynthesis is the process that involves the production of energy and nutrition in presence of light with water and atmospheric carbon dioxide.
