The cell wall is strong an the cell membrane isn't
Answer: few animals can undergo both.
The organism that grows on the body of another organism and derives nutrients from it is known as a parasite. The organism that obtains nutrients from the dead or decaying organic matter is called saprotroph.
Answer:
1. to increase meiosis.
2. to make more efficient cell organelles.
3. to cause the second organism to produce protein
Explanation:
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.
