B. 7
the atomic mass is protons + neutrons.
Answer:
Carbon-Carbon bond is not considered as a noncovalent interaction because electrons are shared between the two carbons forming a strong covalent bond.
Explanation:
Non covalent interactions does not involve sharing of electrons rather it involves dispersed variation of electromagnetic interactions between the molecules.
Examples include;
Hydrogen bond- in order to be formed the donor Atom has to be electronegative
Ionic interactions- These are attractions between two oppositely charged ions
Van der waals- It is formed due to small , transient asymmetric electron distribution around atoms
a term you can use could be <u>Variety</u> or a <u>Variant</u>
Answer: Mammalian red blood cells have a biconcave (doughnut-like) shape. If red blood cells are placed in a 0.3 M NaCl solution, there is little net osmotic movement of water, the size and shape of the cells stay the same; the NaCl solution is isotonic to the cell. If red blood cells are placed in a solution with a lower solute concentration than is found in the cells, water moves into the cells by osmosis, causing the cells to swell; such a solution is hypotonic to the cells. When red blood cells are placed in pure water, water rapidly enters the cells by osmosis and causes the cells to burst, a phenomenon known as hemolysis. If the red blood cells are placed in a solution with a higher solute concentration, water moves out of the cell by osmosis, the cell becomes smaller and crenated in shape; such a solution is hypertonic to the cells.
