Carbohydrates are sugars that come in 2 main forms - simple and complex. This is also referred to as simple sugars and starches. The difference between a simple and complex carb is in how quickly it is digested and absorbed - as well as it's chemical structure.
The permeability of the postsynaptic neuron changes; consequently, its membrane potential is changed as well
The effect of sympathetic nervous system stimulation on the heart is to increase heart rate and myocardial contractility.
In the sympathetic nervous system (SNS), as the sympathetic stimulation increases, the heart rate also decreases along with the force of contraction.
The heart rate increases because of the release of hormones catecholamines - epinephrine and norepinephrine whereas the force of contraction increases because of a higher end-systolic volume [ESV] which requires a forceful heart contraction to pump more blood out of the ventricle which will decrease the ESV value.
The end-systolic volume [ESV] is the amount of blood that remains in a ventricle after a contraction (systole) which is to be maintained at around 50 mL of blood.

Answer:
No. when stomata is blocked, photosynthesis will stop because the CO₂ level will decline within the leaf, stopping the reactions that are light-independent.
Answer:
A) cells of the tail dying and the nutrients being absorbed and reused by the body
Explanation:
The tails of the tadpole die when metamorphosing into an adult frog through a process Called Apoptosis. Apoptosis happens when it’s necessary for the body to kill some cells for development or other factors.
The cells which are killed produces nutrients which are then used and reabsorbed back into the body system of the frog.
