G hemodialysis is a procedure that patients who have limited or virtually non-existent kidney function undergo to remove both waste products and extra fluid from their bloodstream. blood from an artery of a hemodialysis patient is diverted into an artificial kidney where the blood enters numerous tiny fibers.
It is the main endocrine gland and a small structure in the head. It's named the "master gland" because it produces hormones that control other glands and many other body functions including growth. It consists of the anterior and posterior pituitary.
Hope that this helps! Also nice username
Explanation:
Precision can be defined as ability to reproduce a set of results.
The archer would be more precise if all his shots are in a particular place.
Accuracy is a measure of how close the shot is to the target.
The closer the shot to the target, the more accurate it is.
- A contestant with a good precision but poor accuracy implies that most of his shots are far away from the target(poor accuracy).
- Also, the shots are clustered and likely hits a particular spot(precision)

Answer:The correct answer is " a"
LDL contain protein,triglycerides,phospholipid and cholesterol.
Explanation:
Low density lipoprotein,or LDL,are complex aggregates of lipids and protein.Their function is to transport lipids (fats) around the body,in the bloodstream,and to the cells where its required.Apart from this,it also carries triglycerides,phospholipids and fat soluble vitamins.
Lipoprotein is composed of a hydrophobic core that is made up of polyunsaturated fatty acids and cholesterol molecules,along with a lipid membrane that contains protein called apolipoproteins.
There are 4 major classes of lipoprotein:
•chylomicrons
•very low density lipoprotein(VLDL)
•high density lipoprotein (HDL)
•low density lipoprotein(LDL)
Answer:
pre-zygotic reproductive isolation
Explanation:
<em>The molecules regulate the pre-zygotic reproductive isolation mechanism.</em>
<u>Reproductive isolation generally refers to the variety of biological processes that sustain the formation of new species of biological organisms. </u>
Some of these processes <em>act to prevent fertilization or the formation of zygotes between organisms that are not of the same species</em> (pre-zygotic mechanisms) while others <em>ensure that the product of fertilization is invalid</em> in case the former fails (post-zygotic mechanisms).
Some pre-zygotic mechanisms ensure that there exists no form of mating among organisms that are not of the same species due to incompatible reproductive organs, but where this fails, another pre-zygotic mechanism will act so that that the mating will not lead to fertilization and there will not be formation of zygotes.
The prevention of fertilization between organisms with compatible reproductive organs but of different species is carried out by molecules. These molecules ensure that there are locks and keys in place to prevent the fertilization of the egg by the sperm.
