Answer:
See the answer below
Explanation:
Since bacteria are prokaryotes, they have no nucleus and membrane-bound organelles. The outside of a bacterial cell is protected by a structure called a capsule. The cell wall provides a rigid structure that gives the cell its shape. The cell membrane helps to transport ions, nutrients, and waste. The plasmids allow DNA to be transferred from one bacterium to another.
<em>The bacteria are microscopic organisms that are generally classified as prokaryotes. The prokaryotes lack nucleus and other membrane-bound organelles, unlike the eukaryotes. The bacteria cells are enclosed in a protective structure known as the capsule. Immediately after the capsule is the cell wall whose components vary depending on whether the bacteria is Gram-positive or negative. </em>
<em>Towards the innermost part of the cell, after the cell wall is the cell membrane. It acts as a channel for the transport of materials in and out of the cell. Some bacteria cells have short, circular, extrachromosomal DNA known as plasmids which can be transferred from one cell to another.</em>
Answer:
spermatogenesis
Explanation:
The stem cell that is located inside the seminifeous tubules inside the testis of a male, with a high level of testosterone, start the maturation process that last 74 days.
First the stem cell derived into the spermatogonia, the inmature cell that enters into a mitosis division to multiply the cells with a full number of chromosomes.
Later they enter into a meiosis process in which the spermatogonia turn into primary spermatocyte, then into a second spermatocyte, until being a spermatid. After this process the spermatids have the half of the number of chromosomes.
The last step is to maturate the spermatids into sperm cells with all the cell structures and nutrients.
Answer:
An organism would not be able to reproduce without meiosis.
Explanation:
Between meiosis and mitosis, meiosis is by far not as important. If you are a asexual organism, this would be NOT IMPORTANT whatsoever. If you are a sexual organism, this would LARGLY effect you. But on a world scale, this is NOT AS IMPORTANT.
This is because, without mitosis, you could not heal and would die much much younger since your cells could not be replaced. On the other hand, without meiosis, any organism that reproduces sexually would be unable to do so, which could lead to extinction in many, many species. This would not be harmful, however, to species that can also or mainly reporuduce asexually through budding, fragmenting, or sporing. So overall:
<u>Organisms that produce sexually would go extinct. </u>
This is the only real affect I can think of. Since meiosis does not produce any cells aside from reproductive cells. And asexual organisms produce reproductive cells through other means.
