Answer:
The correct answer is - C. Plants.
Explanation:
As we know and also given that the pond is usually smaller and shallower than a lake. Due to this reason, ponds have plants growing on the bottom of them from one side to the other as they get enough light as there is only the photic zone in ponds.
In lakes, there are various zones present and the lakes are deep and big to the ponds and the bottom of the lakes did not get sunlight. Plants require sunlight to grow and lakes are usually too deep to get the sunlight for plants to grow on the bottom.
Answer - Theory
Reasoning - Your best bet and term to describe the evolution by natural selection is theory as to still scientific theory/research is still ongoing and changes can be made in a different direction.
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.
