<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
Answer:
The correct answer is option A More cropland
Explanation:
As the human population will increase, their demand for resources will also increase specifically for the three essentials namely air, water and food. In order to cater the need of increased food demand, more food is needed to be produced and thus more land is required. Apart from agricultural produce, even dairy farms, aquaculture or any other method of production of non vegetarian/other food sources, also require large amount of pasture land or crop land.
The Answer would be A or D but I am going with A if you come up if the right answer good for you
Dont live in the same climate or region. Just a guess. Hope this helps.
