The part of the endometrium that undergoes cyclical changes in response to sexual hormonal levels is the ______.

serosa

functional zone

muscular myometrium

basilar zone

none of the choices is correct

Answer:

functional zone

Explanation:

The endometrium of the uterus is a highly vascularized layer. The endometrium has the innermost of simple columnar epithelium, thick stroma, and the endometrial glands. Functionally, the endometrium has two layers. The functional layer or the functional zone is also called stratum functionalis. It serves to line the uterine cavity and sloughs off during menstruation. The basal layer is deeper and is called stratum basalis. It is permanent and forms a new functional zone after each menstruation.

Describe the mechanism of blood sugar regulation (20 marks)

dedylja [7]

<h2> $Answer \: -$ </h2>

Insulin helps the cells absorb glucose, reducing blood sugar and providing the cells with glucose for energy. When blood sugar levels are too low, the pancreas releases glucagon. Glucagon instructs the liver to release stored glucose, which causes blood sugar to rise.

The pancreas releases glucagon when glucose levels fall too low. Glucagon causes the liver to convert stored glycogen into glucose, which is released into the bloodstream. High BG levels stimulate the release of insulin. Insulin allows glucose to be taken up and used by insulin-dependent tissues, such as muscle cells.p

Why is a frameshift missense mutation more likely to have a severe effect on phenotype than a nucleotide-pair substitution misse

Aneli [31]

Explanation:

A single nucleotide-pair substitution missense mutation causes a change of a single amino acid into another. Aa a result, the produced protein will have an almost normal sequence except for one amino acid.

On the other hand, a frameshift mutation changes the Open Reading Frame (ORF) of the ribosome. The ribosome moves along the mRNA every three nucleotides (codons) and translates them into amino acids that will form the nascent protein. If there is a frameshift mutation (an insertion or deletion of a number of nucleotides not multiple of three) the ribosome will "read" the mRNA differently and will identify different codons than the wild-type sequence, so a large number of amino acids will be different in the mutated protein.
