Answer:
WATER REABSORPTION IN THE COLLECTING TUBULE OF TE KIDNEY
Explanation:
Antidiuretic hormone synthesized by the neurons in the hypothalamus and the posterior pituitary allows for the reabsorption of water from the collecting ducts of the kidneys back into the circulation.
This therefore reduces the amount of water in the urine causing the formation of concentrated urine and reduced volume of urine.
It causes the increased reabsorption of sodium in the ascending loop of Henle adding to the counter-current mechanism which aids the further reabsorption of water from the distal tubules and collecting ducts.
It also allows the constriction of arteries thereby reducing arterial blood pressure.

Carl Woese<span>, </span>Francis Crick<span>, and </span>Leslie Orgel<span> were the first to suggest that RNA could act as a catalyst in 1967. This idea was based upon the discovery that RNA can form complex </span><span>secondary structures. </span>Nick et al. (2000) have reported that ribozyme play a key role in catalyzing tRNA amino-acylation.

Answer:
1. Can bacteria affect any cell? How does it target?
Bacteria are much larger than viruses, and they are too large to be taken up by receptor-mediated endocytosis. Instead, they enter host cells through phagocytosis. Phagocytosis of bacteria is a normal function of macrophages. They patrol the tissues of the body and ingest and destroy unwanted microbes.
2. What causes the damage to your tissues?
When the body sustains damage from trauma, disease or simple wear and tear, it normally results in the formation of a lesion or cartilage gap on your joint surface.

Answer:
Population A has 4590 and population B has 1520 bacteria
Explanation:
Let’s mark bacteria:
a - bacteria from population A
b - bacteria from population B
Every bacteria <em>a</em> needs 4 units of the first nutrient and every bacteria <em>b</em> needs 1 unit of the same nutrient, so we can write it down as:
4*a + 1*b = 19880
Let’s do the same for the second nutrient. Every bacteria <em>a</em> needs 5 units of the second nutrient and every bacteria <em>b</em> needs 6 units of the second nutrient:
5*a + 6*b = 32070
Now there are two equations and two unknowns. From the first equation, we can separate <em>b</em>:
b = 19880 - 4a
Let’s place this <em>b</em> to the second equation:
5a + 6*(19880 - 4a) = 32070
5a + 119280 - 24a = 32070
119280 - 32070 = 24a - 5a
19a = 87210
a = 4590
This can be brought back to: b = 19880 - 4a
b = 1520
