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)
so if you look up things that can cause an asthma attack it will also show that viruses and bacteria are a cause. with asthma you lungs could already be inflamed as well as your air way wich makes it harder to breath. when you have c-19 it will inflame your lungs even more so it makes it even harder to breath given an asthma attack. more asthma attack now are probably caused by c-19 because it is all over the place and the percent of asthma attack by virus has dramatically increased.
Answer:
The correct answer is D. proliferation and differentiation.
Explanation:
Primary immune response occurs due to the first exposure of an antigen to the immune system. The primary immune response is generally delayed by many days because it takes time for B and T cells to become cloned and to proliferate and differentiate.
Then after several days of proliferation and differentiation of activated T and B cells, T cells become effector T cells and B cell becomes plasma cells which then eliminates the antigen. Memory B and T cells are also produced during this process which helps in generating a quick immune response during the second and subsequent exposure of that antigen.
So the correct answer is D. proliferation and differentiation.
