Answer: Option (b) is the correct answer.
Explanation:
An atom which gains electrons becomes negatively charged and an atom that donates electrons become positively charged.
Therefore, when we rub a silver coin against a wool cloth then cloth becomes positively charged this means that the cloth has lost electrons and the silver coin has gained electrons.
Thus, we can conclude that the statement silver coin gained electrons is true.
Answer:
If the chimpanzee’s zygote has 48 chromosomes, one would expect to find 24 chromosomes in a chimpanzee’s egg.
Explanation:
In a living organism, somatic cells are diploid and possess the full chromosome load, while gametes -sex cells- possess half of the total chromosomes, they are haploid.
The zygote of any organism that reproduces sexually results from the union of a male gamete and a female gamete, so its chromosome load is complete.
<em>This means that if the chimpanzee has 48 chromosomes in its cells, the female sex cell - the egg - has 24 chromosomes.</em>

Answer:
Superantigens produce intense immune responses by stimulating lymphocytes to produce cytokines.
Explanation:
Superantigens are a group of bifunctional proteins that interact with at least two receptors expressed on different cells. The superantigen´s receptors in lymphocyte T is located in the same place where the lymphocyte interacts with a conventional antigen, RCT. The capability of these superantigens to join their receptors in many T cells, shoots a series of processes that conduce to cellular activation, differentiation, proliferation, and great production and release of cytokine.
Superantigens constitute the most potent natural immunostimulators known.
