Because they are the essential micronutrients for the different metabolites of living organisms?
Answer:The answer is option A sister chromatids are separated from each other to form gametes.
Explanation:
Meiosis is a type of cell division which produces 4 daughter cells with different genetic material. The ploidy number or set of chromosomes is reduced to half in the newly formed daughter cells.This process usually proceeds in two divisions-meiosis I and meiosis II with four stages in each division which are prophase, metaphase, anaphase and telophase.Sister chromatids separate from each other during anaphase II of meiosis II which produces four haploid gametes from two intermediate cells formed by meiosis I.Thus, sister chromatids are separated from each other to form gametes is the correct answer.
Answer:
A. Molecular changes such as extracellular signals on extracellular ligands can result in quick changes in cell behaviour. One example is insulin. Upon insulin binding on the receptor on the cell membrane, the cell release GLUT4 transporters (for muscle cells) to increase uptake of glucose.
B. Slow changes in cell behaviour can be observed for other lipophilic hormones or intracellular receptors such as glucocoortoid or estrogen which reacts with receptors in the cells.
C. Insulin is required to maintain a constant blood glucose level and hence levels of insulin has to be mediated in correspondence to the blood glucose levels. Fast acting signalling is thus required for homeostasis of blood glucose levels. Where for such lipophilic hormones such as steriods, glucocortoid, these hormones tend to have a longer lasting effect and hence results in a slow change.
Part 1:
A solution that causes a cell to swell is a hypotonic solution.
In an isotonic solution, there is no change in the size of the cell.
All three cause osmosis.
A solution that causes a cell to shrink is a hypertonic solution.
Part 2:
1. H. Energy
2.D. Endocytosis
3.G. Diffusion
4.B. Exocytosis
5.E. Facilitated Diffusion
6.A. Osmosis
7.C. Active Transport
8.F. Passive Transport
Sorry. I don't know how to explain part 3 ,but I tried and failed so I deleted it. Part 1 and 2 are correct though.
Answer;
b. nitroglycerin may give incomplete or no relief of myocardial infarction pain.
Two conditions related to cardiac compromise are angina pectoris and myocardial infarction. In comparing the two, remember that nitroglycerin may give incomplete or no relief of myocardial infarction pain.
Explanation;
-Angina pectoris is the chest pain or discomfort due to coronary heart disease. It occurs when the heart does not get enough blood, due to blockage or narrowing of one or more heart's arteries.
-Myocardial infarction occurs when there is decreased blood flow or stoppage to a part of the heart, resulting to the heart muscle damage.
-Nitroglycerin extended-release capsules are used to prevent chest pain (angina) in people with a cardiac compromise. However, Nitroglycerin may give incomplete or no relief of myocardial infarction pain.
