Answer:
Option B) functions to increase sodium reabsorption.
Explanation:
Aldosterone is an hormone secreted by the cortex of the adrenal gland. The adrenal gland is situated at the superior poles of the right and left kidneys.
Aldosterone regulates sodium homeostasis and as such helps to control blood volume and blood pressure.
Aldosterone is secreted in response to decreased blood pressure (hypotension) to increase sodium reabsorption from urine, sweat, and the gut. Also excessive aldosterone levels (too high sodium) can lead to high blood pressure (hypertension).
The answer is D) desertification and deforestation
To know the answer you can rule out the non-possibilities. A is not correct because farmers use them all the time. B is not correct because water and pesticides can flow downstream and carry and deposit sediment. C is not correct because farmers can flood their own farms. When they plant things and a food comes, all of those plants will die or their roots will detach which lowers the food that can be sold. D is correct because farmers don't farm in the desert or the forest, so it would not be an impact of farming.
Drilling for fossil fuels.
This is because the main fossil fuels are not typically found in the rainforest. To also back up this claim, use the process of elimination.
The last choice, demand for rainforest products, is obviously incorrect as that would mean expansion into the rainforest to gather said products.
Shortage of food sources wouldn't be the correct answer either as food sources aren't typically found in the rainforest among popular demand and food can be shipped into the country as well.
Overcrowding in cities would also lead to expansion, where to can differ based on location but to rainforests or anywhere surrounding the area would be preferred or desirable.
Hope this helps!
Answer:
The correct answer is d. photorespiration
Explanation:
In the C3 plant, the Rubisco enzyme is important that fix CO2 into organic molecule by binding with CO2. Rubisco can also bind to oxygen when the oxygen concentration increases in cells which leads to the loss of fixed CO2 and waste of energy which is called photorespiration.
So when stomata are open CO2 comes in and O2 goes out of the cell which maintains the high CO2 concentration in the cell but during hot days C3 plants close stomata to prevent water loss.
So closing of stomata decrease the intake of CO2 and increase the oxygen concentration inside the cell. So in increased temperature and high oxygen concentration, the rubisco enzymes bind to O2 and promote photorespiration.
