Explanation:
Hardy-Weinberg principle can be illustrated mathematically with the equation: p2+2pq+q2 = 1, where 'p' and 'q' represent the frequencies of alleles. ... The principle behind it is that, in a population where certain conditions are met (see below), the frequency of the alleles in the gene pool will be constant.
Answer:

The statements in options A,B,C,D and E are all correct.
A. Invertebrates lack a back bone
B. Ecdysozoans typically posses a flexible exoskeleton that protects these animals from harmful external factors like water loss.
C. Deuterstomia, Lophotrochozoa and Ecdysozoa are classes of Bilaterians.

Answer:
Humoral immunity secretes antibodies to fight against antigens, whereas cell-mediated immunity secretes cytokines and no antibodies to attack the pathogens. The Humoral immunity is rapid or quick in their action against antigens, while the Cell-mediated immunity show delay though permanent action against any pathogens. Cellular immunity is a protective immune process that involves the activation of phagocytes, antigen-sensitized cytotoxic T cells and the release of cytokines and chemokines in response to antigen
