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:
Enzyme pH levels also change the shape of the active site and affect the rate of enzyme activity. Each enzyme has its own optimal range of pH in which it works most effectively. In humans, catalase works only between pH 7 and pH 11. If the pH level is lower than 7 or higher than 11, the enzyme becomes denatured and loses its structure. The liver sustains a neutral pH of about 7, which creates the best environment for catalase and other enzymes.
Natural Selection is not random because the organisms of a species that do not survive have a non-desirable genetic quality, a disease, injury, etc. This leaves the better organisms of a species to survive and reproduce, which creates a stronger and larger species.
Answer:
The matrix is the innermost compartment of a mitochondrion. Here, the Kreb's cycle occur breaking down pyruvic acid into carbon dioxide in a series of reactions.
<em>Note: The question is incomplete. The complete question is given below:</em>
<em>The (matrix / stoma / cytoplasm / nucleolus) is the innermost compartment of a (cytoplasm / cell wall / mitochondrion / nucleus). Here, (glycolysis / the Krebs cycle / fermentation / NAD+) occur(s), breaking down (citric / pyruvic / lactic / nitric) acid into carbon dioxide in a series of reactions.</em>
Explanation:
The mitochondria is a double-membrane bound cell organelle found in the cytoplasm within which the biochemical processes of cellular respiration and energy production occur. Cristae are folds of inner membrane that project into the matrix. The matrix is a gel-like material in the innermost compartment of a mitochondria and is the site for the Kreb's or Citric cycle.
The Kreb's cycle is the third stage of cellular respiration (the first is glycolysis in which a molecule of glucose is broken down into two molecules of pyruvic acid; the second is the preparatory stage which oxidizes two molecules of pyruvic acid to two molecules of acetyl-CoA). In this cycle, the two molecules of acetyl-CoA produced in the preparatory stage is broken down into carbon dioxide in a series of eight energy-extracting reactions producing 2 ATP, 6 NADH, 2 FADH2 and releasing 4 CO2.
Answer:
Explanation:
Aldosterone is a hormone which is produced by the adrenal glands which are present above the kidneys. The role of aldosterone is to regulate the blood pressure. It causes the reabsorption of water and salts into the bloodstream during the kidney filteration process. Hence, maintains the blood volume, restors blood pressure and salt level.
Renin is an enzyme. It facilitates chemical reactions which stimulates the synthesis of angiotension II, it directs the synthesis of aldosterone.
