Explanation:
Transpiration is the process where plants absorb water through the roots and then give off water vapor through pores in their leaves, so D would be your answer

Out of the following given choices; a. reticular formation
b. cerebral cortex * c. limbic system d. hypothalamus
The answer is B. This region of the brain is responsible for cognition, consciousness, thought, and memory. It is these qualities, especially self-awareness
and cognition, that distinguishes humans from other animals. It enables humans to reason, plan and have great social intelligence.
This is an example of negative feedback.
After a big meal, glucose levels in the bloodstream increases. The body recognises this change and goes through homeostasis, or the regulation of bodily state or internal environment.
The pancreas secretes insulin, which then binds to insulin receptors. This will result in the uptake of excess glucose from the bloodstream into cells and converted into glycogen to be stored in cells as energy storage molecules.
Since there is the counter effect of body (i.e. when blood-glucose concentration increases, the body sends a signal to decrease the blood-glucose concentration, this is called a negative feedback (instead of a positive feedback, which occurs if for e.g. the body signals cells to increase blood-glucose concentration even after blood-glucose concentration increased after a heavy meal).
Hope this helps! :)
