Answer:
The diagram is attached below.
Explanation:
when sodium and chlorine comes close together they form anion and cation. The compound formed is called sodium chloride.
Both atoms bonded together through ionic bond.
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.

Answer:Evolution is a process that results in changes in the genetic material of a population over time. So its true!
Explanation:
This is correct!
Answer:
True.
Explanation:
The immunoglobulins, MHC ( major histocompatibity complex) and TCR (T cell receptor) plays an important role in the immune system. They protect the individual from the harmful antigens.
The evolution of immune system has done the duplication process. The genes gets duplicated and evolved to perform the specific function. The Immunoglobulin, TCR, and MHC gene evolve by the process of duplication. These genes mainly acts against the specific pathogen and shows the selection according to the primordial antigen receptors.
Thus, the answer is true.
Light-independent reactions, or dark reactions,[1] of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions occur in the stroma, the fluid-filled area of a chloroplast outside the thylakoid membranes. These reactions take the products (ATP and NADPH) of light-dependent reactions and perform further
