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.
A person who specializes in the study of animals is called a zoologist. Zoologists who study certain kinds of animals have their own names.
Cholesterol travels in the blood transported in molecules called lipoproteins.
Answer:
Phospholipids
Explanation:
Phospholipids are a particular kind of lipid (an oil) that forms a two-layered surface that surrounds and protects all living cells. The phosphates are essential to forming this bilayered structure. This membrane has a semipermeable function that selectively allows some elements and molecules to go in or out of the cell and thus helps maintain the cell in equilibrium.
