Stimulated by the action of the ions on its receptors, the pump transports them in opposite directions against their concentration gradients. ... The sodium-potassium pump carries out a form of active transport—that is, its pumping of ions against their gradients requires the addition of energy from an outside source.
Answer: Covalent bonds form when atoms share their valence electrons with other atoms to become a more stable molecule.
Explanation: Atoms form covalent bonds as a result of the Octet Rule. The Octet Rule states that all atoms in a molecule need to have eight electrons in their valence shell. This rule can be satisfied by sharing, losing or gaining electrons. A covalent bond allows atoms to satisfy the Octet Rule via sharing.
Answer: Both a and b
Explanation:
The presence of C-C and C-H bonds in fat makes them insoluble in water as they are non polar: do not dissolve in water. These are rich in energy in that their breakdown produces more energy than even carbohydrates themselves.
