Answer:
well i would help if i could see the question
Explanation:
Answer:
B. It becomes a positive ion.
Explanation:
The number of electrons and protons is eleven in sodium. After sodium (Na) has transferred its electron to the chlorine atom (Cl) it becomes a positively charged ion. This is because as electrons are negatively charged, losing of an electron will increase the number of protons (i.e 11) as compared to the number of electrons (i.e 10) in sodium (Na) atom. Hence, a positive charge will be acquired by the sodium (Na) ions.

is important that antibodies have a symmetrical quaternary structure to create
two identical binding sites for antigens. An antibody is a relatively large
protein having a Y-shape. Plasma cells produce antibodies which are then used
by the immune system to fight off pathogens (e.g. bacteria and virus). The antibody
is able to recognize the antigen of the pathogen. It binds with it either to
neutralize it directly or “tag” the microbe for future attack by other parts of
the immune system. </span>

Explanation:
A scientific claim is defined as a statement which is a conclusion obtained from numerous experiments and observations.The scientific claim usually remains the same in the provided conditions. In the first statement, Copernicus's model stating that the planets revolve in the circular orbits around the sun was not accepted and thus, it is not a scientific claim. Similarly, Newton's laws of motion are uniform and work properly in the environment. Thus, it also does not form a scientific claim.
