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.

borishaifa [10]
Anterior Pituitary or adenohypophysis has two parts: pars distalis and pars intermedia..though they are kinda joined in humans.
•Pars distalis (actuallyknown as the anterior pituitary) secretes hormones like Growth Hormone or Somatotrophin, Prolactin, TSH, ACTH,LH,FSH.
•Pars intermedia secretes only one hormone MSH (Melanocyte Stimulating Hormone)
•Posterior pituitary or Neurohypophysis stores two hormones (originally secreted by the hypothalamus) which are Oxytocin and Vasopressin or ADH.

Cheers..dont forget to deem this answer as a brainy answer :)

*will give brainliest!*<br><br> Why is the biosphere so fragile?
icang [17]
I believe the biosphere is fragile, because over time all of the pollution us humans have made; If its from air pulloution, acid rain or even water pollution. the toxic acids over time have made the biosphere and the ozon layer weaker and more thin. which causes the biosphere to become weaker.
