it’s somehow re-jiggered its
taste system so that the attractant that humans used to draw the insect to
poison bait—the sugar glucose—now tastes bitter to the roach, and they avoid it.
cockroaches began appearing that avoided the baits, and did so not because they
were averse to the poison, but because they were averse to the attractant, glucose. This new
trait turned out to be heritable, that is, it had a genetic basis.
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
Answer:
The mentioned parental types are c+m- and c-m+. Thus, the recombinants will be c+m+ and c-m-.
Now, the given distance between c and m is 8 map units. Thus, the recombinant frequency is 8% or 0.08.
The total recombinants from 1000 plaques will come out to be 80,
Thus, the recombinants of each type will be 40.
Total parental type will be 920, and therefore, each parental type count will be 460.
Thus, expected c+m- = 460, expected c-m+ = 460, expected c+m+ = 40 and expected c-m- = 40.
