Lesechka [4]

No their babies won't look alike.

<h3>Explanation:</h3>

Both the couples mentioned here i.e. Sally - Harry and Emily - Ken are both identical twins. So they have similar pairs of genetic setup. This was possible because they developed from same zygote.

But during gametogenesis, crossing over and independent assortment occurs which brings about variation in genetic setup among the offspring. And it's very less probable that same crossing over will occur between the gametes of these couples. So, their offsprings won't look same.

Alexus [3.1K]

Answer:

B) Coating of microbe to aid phagocyte recognition

Explanation:

Opsonization is the process and mechanism which targets the foreign body and helps in the recognition of the pathogen by the phagocytic cells such as the macrophages and dendritic cell.

The opsonization enhances the process of phagocytosis as the opsonin substances which could be the antibodies, proteins or other molecules which could be easily recognised by the phagocytic cells gets attached to the pathogen.

Thus, Option-B is the correct answer.

Opsonization is the coating of a particle with proteins that facilitate phagocytosis of the particle by tissue macrophages and activated follicular dendritic cells (FDCs) as well as binding by receptors on peripheral blood cells
