Answer:
im pretty sure it is underpopulation.
Answer:
The correct answer will be-
1. decrease in blood volume
2. secretion of renin from juxtaglomerular apparatus
3. production of angiotensin II
4. secretion of aldosterone
5. sodium reabsorbed from distal tubules and collecting ducts
Explanation:
The RAAS pathway or Renin-angiotensin II-aldosterone pathway gets activated in the human body to maintain the osmolarity and blood volume.
When the receptors in the blood sense the low volume of water in the body sends signals to the brain which activates the secretion of the renin from the juxtaglomerular cells. Renin helps converts the inactive angiotensin to angiotensin I and II which help reabsorption of sodium ions. This activates the production of aldosterone which increases the reabsorption of the sodium ions into distal and collecting ducts.
In the diagram we see a cell plant, with a few structures numbered:
0. Vacuole
,
1. Chloroplast
,
2. Nucleus
,
3. Cell wall
The answer options correspond with the functions of these structures:
0. Vacuole- Has secretory, excretory, and storage roles (B)
,
1. Chloroplast - It makes the photosynthesis (D)
,
2. Nucleus - Serves as the control center of the cell and contains the genetic information (A)
,
3. Cell wall ,- ,Provides structural support to the cell (C)
Answer:
Triploid
Explanation:
The process whereby gametes produced by different sexes of the same species of organism come together is called FERTILIZATION. A gamete is said to be HAPLOID (n) if it contains one set of chromosomes while it is DIPLOID (2n) if it contains two sets of chromosomes.
Hence, if an haploid (n) and diploid (2n) gamete unites, a zygote that is TRIPLOID (3n) emerges or forms. A triploid zygote will have three sets of chromosomes i.e. n + 2n = 3n.
