The antibodies that can bid to large parasites are IgE. IgE is a type of antibody synthesized by plasma cells and has only been found in mammals. If you have an allaergy, the immune system overeacts to an allergen by producing antibodies IgE. These antibodies travel to cells that release chemicals, causing an allergic reaction.

Answer:
The main difference between prophase I and II is that during prophase 1, the pairing of homologous chromosomes or the synapsis allows the non sister chromatids to cross over at chiasmata, leading to genetic recombination between chromosomes. During prophase II,synapsis does not occur; hence, no genetic recombination takes place between the chromosomes
During Prophase I the Centrosome is duplicated during the interphase, which is a process prior to prophase while in Prophase II, the Centrosome is duplicated during the prophase II due to the lack of an interphase.
Biological evolution is the process by which populations of organisms change over time. How could natural selection lead to the evolution of a species?
Answer:

Explanation:
Density (D) is a quantity defined as mass (m) per unit volume (v): D = m ÷ v. Since these three quantities are related, you can find one of them if you know the other two. This is more helpful than it sounds because density is often a known quantity that you can look up, assuming you know the composition of the material.
Calculations are straightforward for solid objects, but things get more complicated for liquids, where density changes with temperature, and for gases, for which density is dependent on temperature and pressure.
