<em>Blood typing is done so you can safely donate your blood or receive a blood transfusion. It is also done to see if you have a substance called Rh factor on the surface of your red blood cells. Your blood type is based on whether or not certain proteins are on your red blood cells. These proteins are called antigens.</em>

Answer:
The correct answer would be - 16 chromosomes or 8 chromosome pairs per cell.
Explanation:
In the body of an organism, all the somatic cells have the same number of chromosomes irrespective of their location in the body which is 2n or diploid. Liver cells would also have 2n number of chromosomes. The diploid number of cells are produced by the mitosis type of cell division or by fusing the sex cell that are egg cells and sperm cells. These sex cells are haploid of n number of cells or haploid.
If a sex cell as given in question sperm cells have 8 chromosomes then the liver cell would be 2n because sex cells after forming a zygote develooped to all other somatic cells including liver cells.
Sex cell = n = 8 chromosomes
liver cell - 2n = 2×8 = 16 chromosomes.
Answer:
3. Polysaccharide carbohydrate
EXPLANATION:
The POLYSACCHARIDE capsule of Streptococcus Pneumoniae is the major virulence factor in it's invasion and subsequent infection.
The capsule helps to avoid phagocytosis which is a defence mechanism by the body.
The polysaccharide capsule also gives the bacterial organism several serotypes.
The pneumococcal vaccine is derived from the organism's capsule.
