Answer:
Genotype can be described as the genetic makeup of an organism. Phenotype can be described as the physical characteristics which are observed in an individual.
Our genotype influences our phenotype.
For example, lets consider a male parent to be homozygous for brown eye colour which is dominant, BB. The female parent has blue eye colour and is recessive, bb.
Let's make a punnet square,
b b
B Bb Bb
B Bb Bb
The results from the punnet square tell that all of the offsprings will have heterozygous genotype Bb, and the phenotype will be brown eyes.
Chromium is already being used in the medicine industry to treat cancer (ovarian cancer in the form of chromium phosphate). So chromium may be used to build the efficiency of cancer treatment and make it more cost-efficient.

Answer:
B cells are at the centre of the adaptive humoral immune system and are responsible for mediating the production of antigen-specific immunoglobulin (Ig) directed against invasive pathogens (typically known as antibodies).
Explanation:
T cells are a part of the immune system that focuses on specific foreign particles. Rather than generically attack any antigens, T cells circulate until they encounter their specific antigen. As such, T cells play a critical part in immunity to foreign substances.
The nucleus is a spherical object, and it controls cell activity.
