Answer:
Durring isolation, one may feel lonely, afraid, unloved, and unimportant.
<h3><u>Answer and explanation;</u></h3>
- DNA is a double stranded molecule. Covalent and hydrogen bonds pray important roles in the functioning of DNA molecules.
- <em><u>Covalent bonds occur within each linear strand and strongly bond the nucleotide bases, sugars, and phosphate groups occurring both within each component and between components.</u></em>
- <em><u> Hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing.</u></em>
- Hydrogen bonds helps the complementary base pairs in DNA; guanine with cytosine and adenine with thymine to connect to one another. The hydrogen bonds between these complementary pairs helps keep the two strands of DNA helix together.
Answer: Although produced in both males and females, by the mid-teens, estradiol production in females is 8 times greater than it was before puberty, while testosterone production in males is 20 times greater than it was before puberty.
Explanation:
Puberty is the transition phase in which somatic growth and sexual development are completed, with the consequent acquisition of reproductive capacity. Estradiol is the most potent and abundant estrogen, it is secreted by the ovarian follicle granulosa cells and also by the corpus luteum. testosterone is the hormone responsible for the emergence of secondary sexual characteristics, sperm production and increased sexual drive, aggression, height growth and physical strength, among others. There are many differences in body composition between both sexes, and those differences are also present in the hormones concentration. While estradiol is 8 times greater after puberty in females, this number is 20 times greatern in males, when we are talking about testosterone
D) take in nutrients because endocytosis is the process when a cell takes in food
Answer:
The effect of amanitin on the maximum elongation rate for the wild-type and modified RNA polymerases is that it binds to the RNA polymerases, and reduces the process of translocation which is essential for RNA synthesis that is required for RNA polymerases elongation.
Explanation:
Amanitin is a peptide that is cyclic in nature. It is repelled by water thereby making it an hydrophobic peptide.
Amanitin is a toxic peptide that is found in Amanita ( a type of mushroom).
Alpha Amanitin in particular is the one that affects the elongation rate of RNA Polymerases in the body.
When Alpha Amanitin gets into the body system, it travels straight to the liver and due to its very strong affinity for RNA polymerases, it immediately attaches itself to them.
After the attachment, Alpha Amanitin, is disturbs the bridge helix found in RNA polymerase, preventing the hindering and slowing down the proces of translocation from happening.
Once translocation is hindered, RNA is no longer synthesized. Hence, the elongation of RNA polymerases is hindered and this results in severe illness in the body such as liver failure, cytolysis of the liver
