Answer:
1. N. Valency
The electrons in theoutermost occupied shell (or shells) determine the chemical properties of the atom; it is called the valence shell.
2. I. Non polar covalent
Nonpolar covalent bonds are a type of chemical bond where two atoms share a pair of electrons equally with each other. Polar covalent bonding is a type of chemical bond where a pair of electrons is unequally shared between two atoms.
3. A. ATP
ATP is called as energy currency
4. F. Fat
Fat is reserved food for long time in the form of cholesterol
5. G. Functional group
NH2= amino group
OH= hydroxyl group
6. H. Hydrolysis
7. E. Exothermic reaction
Exothermic reaction releases energy whereas endothermic reaction utilizes energy.
8. L. Products
Molecules that are involved in reaction are called substrates whereas molecules that are released from reaction are called products.
9. J. pH
10. M. Ribose
Uracil present in RNA and sugar is ribose.
