I would say false because fossil fuels are formed by dead animal matter
So basically you have to like multiply and stuff so you would freaking get like 250 or something.
Answer:
Parasympathetic nervous division
Explanation:
The parasympathetic division of nerves is a part of the autonomic nervous system which gets activated during the relax conditions.
The parasympathetic nervous system is the opposite of the sympathetic nervous system which gets activated during the stress condition.
The parasympathetic division gets activated when the level of cortisol and adrenaline gets decreased and the body responds by detoxifying, digesting and building immunity.
Thus, Parasympathetic nervous division is the correct answer.
<h2>Urea </h2>
Explanation:
Urea is a small nitrogenous compound which is the main end product of protein catabolism in mammals
- Urea is a nitrogen-containing substance normally cleared from the blood by the kidney into the urine
- It is made predominantly in the liver from ammonia and bicarbonate and is one of the main components of urine
- The rate of synthesis varies from 300 to 600 mmol/day depending on the protein intake
- All of this urea eventually finds its way into the urine
- Because urea makes up a large part of the obligatory solute excretion, its osmotic pressure requires significant volumes of water to carry the urea
- Urea passively crosses biological membranes, but its permeability is low because of its low solubility in the lipid bilayer
- Some cells speed up this process through urea transporters, which move urea by facilitated diffusion
- Urea is passively reabsorbed in the proximal tubule, but its route of transport is not clear
- Urea transporters have not yet been identified for the proximal tubule
