Answer:

Explanation:
B-cells engulf an antigen by endocytosis.
<u>Endocytosis:</u>
The process by which cell takes up external materials by fusing them with plasma membrane is called endocytosis.
After engulfing the antigen, B-cells become sensitive to the pathogen.

Answer:
7 % progeny will show wild type phenotype
Explanation:
Parent 1: Normal wings and small eyes : DDee
Parent 2 : Downward wings and normal eyes : ddEE
DDee X ddEE = DdEe ( All have normal wings and normal eyes )
When a F1 individual is test crossed:
DdEe X ddee =
De/de = Parental
dE/de = Parental
DE/de = Recombinant
de/de = Recombinant
Recombination frequency between the two genes is 14% hence DE/de and de/de will each have 7% frequency. Since DE/de ( DdEe ) will give wild type phenotype, it means that 7% progeny will have wild type phenotype.
When listing the levels of organization in organisms from smallest to most complex, "tissue" would be just below organs in complexity because organs are made of tissues.
What do you mean divide multiple parts into a blender?
Answer:
A chain reaction refers to a process in which neutrons released in fission produce an additional fission in at least one further nucleus. This nucleus in turn produces neutrons, and process repeats. The process may be controlled (nuclear power) or uncontrolled (nuclear weapons).
