Answer:

B. IgM

Explanation:

IgM is the antibody isotype that is the first antibody type secreted by plasma cells following the initial encounter to the antigen. As soon as the B cells encounter an antigen, the specific immune response is generated by the formation of plasma cells which in turn secrete IgM antibodies.

The function of IgM antibodies is to activate the complement system and to stimulate the agglutination of microbes.

Which of the following is a correct DIFFERENCE between sexual and asexual reproduction?
jolli1 [7]

Answer:

A. Sexual Reproduction creates genetically different offspring.

Explanation:

Sexual Reproduction is created through 2 different opposite parties, in which the product takes around half of the genes from each individual parties. The traits that are shown are then decided on whether or not they are dominant or recessive or non-existent.

In a Asexual Reproduction, the reproductive capabilities of both parties are found inside one organism. The organism is able to produce both the sperm and egg, and therefore do not need a partner to reproduce. This means that the DNA inside the body is the only source for production, and that there will be very little variation in the DNA.
