Answer: A because two of the same pairs are homologous
Answer:
The correct answer would be "Can prevent genetic diseases".
Cloning refers to the process of making an identical copy of organism, cell or DNA fragments.
One of the applications of cloning is eradication or prevention of genetic diseases.
It is done by isolating the correct or functional gene and make copies of it in in-vitro conditions.
The gene or DNA fragment is then inserted back into the cell.
With advancement in cloning process and understanding of stem cells, cloning process also favors tissues and organ harvesting which also help in reducing diseases.
Answer:
B.
Explanation:
whenever a organism grows the cells seperate to make up more room for the organism to keep growing until adulthood to elderly-hood
<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
