At the end of meiosis, there are FOUR cells with HALF the amount of DNA.
Meiosis is a kind of cell division that produces genetically different daughter cells. Unlike mitosis, which produces genetically identical cells, meiosis goes through 2 divisions that leads to 4 daughter cells.
In meiosis, the parent cell first duplicates all its genetic material, just like what they do in mitosis. Then it divides, leading 2 genetically identical daughter cells. Mitosis ends here, but in meiosis, the 2 cells divides themselves again, but without duplicating their DNA. This leads to the 4 daughter cells with only half of the number of chromosomes.
We call these cells haploid. They're usually common in gametes. For example, a normal body cell in human has 46 chromosome, but in the cells after meiosis, they only have 23.
The answer is Henry Clay.

Answer:
d) Plantae.
Explanation:
Kingdom Plantae includes plants which are multicellular organisms and have tissue or organ system level of body organization. These organisms have a cell wall made of cellulose and bear chlorophyll in chloroplasts which in turn allow them to carry out the process of photosynthesis. All the green plants are placed in Kingdom Plantae.
Explanation:
<em>Immunological memory</em> is the property of the immune system to store information about a stimulus so it can mount an effective response if it encounters the same stimulus again being this second response quicker and stronger even after years since the first encounter.
This kind of response is dependent on many subpopulations within T and B lymphocytes and NK cells. When encountering an antigen, B cells recognize it by membrane antibody specifically binding to the antigen and then being activated to expand rapidly with their progeny clones differentiating into plasma and memory B cells, these last ones have a long life span to remain in the body, ready when another encounter with the same stimulus occurs, this is how the basis for effective immunizations happens.
I hope you find this information useful! Good luck!
