Answer:
The practice value of serial dilution is done to make an accurate amount of concentration from a dense concentration of cell. In this several process and dilution process is followed.
Explanation:
The process which is followed is taking the sample which is to be diluted of known volume. And after that the dilute or some special solvent is added to make it dilute. The volume of solvent is known.
This process is followed until we get the accurate amount of diluted solution which is to be processed. There is significant value of serial dilution for experiment for other laboratory work. For having a perfect diluted solution, a particular expert of that field is required.
<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
Yes, short answer, I can not give you the specifics (consult your biology textbook)
