What is in the cloud of negatively charged particles that surrounds an atom? O A. Neutrons
B. Protons
C. Proteins
O D. Electrons

D

Explanation:

We are looking for a negatively charged particle that is part of the cloud around an atom. Let’s analyze each answer choice.

Neutrons are neutral, and they have no charge. Therefore, A is incorrect.

Protons have a positive charge, so B is also incorrect.

Proteins are not part of the atom or in the cloud that surrounds one, so choice C is wrong as well.

Electrons are negatively charged, and they are in the cloud that surrounds an atom. Therefore, D. Electrons is correct.

it enhances antibody production by t cells of the adaptive immune system.

hope i'm right

explanation:

i would go with b

cytokinesis occurs after telophase so that eliminates d

and the entire reason for cytokinesis is for cellular reproduction
