D: Surface-water runoff from rain
Answer:
Increased global temperatures, leading to a 20% reduction in rainfall
Explanation:
According to this question, forest fires are becoming rampant in tropical rainforests. Although this occurrence is natural, tropical rainforests do not typically undergo this natural process due to the average yearly amount of rainfall. This means that the high amount of rainfall in tropical rainforests help prevent or reduce the high cases of forest fire incidence.
However, the recent increased occurrence of tropical rainforest fires is most likely attributed to an INCREASE IN GLOBAL TEMPERATURES, LEADING TO A 20% REDUCTION IN RAINFALL. This is because an increase in the global atmospheric temperature causes the reduction of the amount of rainfall, which naturally helps curb the occurrence of forest fires.
As mean arterial pressure increases, <u>the frequency of action potentials from the </u><u>baroreceptors</u><u> increases,</u> informing the medulla oblongata that blood pressure has indeed increased.
- Special receptors called baroreceptors monitor variations in your blood pressure.
- The aorta and carotid sinus both contain significant baroreceptors. The walls of the arteries stretch when the blood pressure in the aorta or carotid sinus rises, stimulating an increase in baroreceptor activity.
- Action potentials are more quickly fired when baroreceptors are activated, with the speed being inversely correlated with the mechanical stretch.
- The brain interprets the information that the baroreceptors send as a rise in blood pressure.
- The blood vessels, heart, and kidneys are just a few of the bodily organs that get signals from the brain to lower blood pressure.

Answer:
The correct answer is - reuptake of the neurotransmitter molecule into the axon through a membrane transporter.
Explanation:
The action of a neurotransmitter at the postsynaptic cell or postsynaptic potentials is terminated by any of these mechanisms that are enzymatic degradation, diffusion or reuptake into the presynaptic cell by specific transporters.
After the desired biological response by postsynaptic potentials, in order to avoid over stimulation or termination of the postsynaptic potentials the neurotransmitter is taken back into the axon through a membrane transporter. This mechanism is to maintain a balance.
