When blood calcium levels drop, glands embedded in the posterior thyroid secrete parathyroid hormone, which stimulates osteoclastic activity. It is made up of parathyroid glands that lie behind the thyroid glands. The reason why it is important because it controls calcium level in the blood and within the bones. It controlled by the low calcium levels in the blood it restorative parathyroid secretion whereas the high calcium levels in the blood stop the release of parathyroid hormone.
The genotyoe of the offspring can be obtained from the genotype of the parents using a punnet square.
<h3>What is genotype?</h3>
The term genotype refers to the sum total of the genes that an organism receieves from its parents. We have to note that genes often occur in pairs called alleles. The combination of gene alleles controls the expressed trait in the organism.
This question is incomplete. However, we do know that the genotyoe of the offspring can be obtained from the genotype of the parents using a punnet square.

<em>Helloo!!! :D</em>
Explanation:
Full Question: The membranes of both B cells and the cancer cells are largely composed of phospholipids. Explain how, when the membranes are fused, the polar parts of the phospholipids from one cell will interact with the phospholipids from the other cell and how the nonpolar parts of the phospholipids from one cell will interact with the phospholipids from the other cell.
<em>happy to help!!!! :D</em>
Answer:
Four.
Explanation:
Initially four haploid spores are produced by meiosis. We know that during meiosis pairing between homologous chromosomes occurs and this created genetic difference between the divided cells. Exchange of genetic material doesn't occur during mitosis so mitotically divided cells are similar. Thus when spores divide by mitosis and become eight in number, here will be no new genetic difference.
The complete sentence will be -
A nucleus within an ascus undergoes meiosis, producing four haploid spores, which then undergo mitosis, producing eight haploid ascospores. These haploid ascospores contain a maximum of four different genetic types.
