1.... Its E) Hydrogen Bond...
A hydrogen Bond is a bond present between a hydrogen atom and a highly electronegative atom such as Oxygen, Florine and Nitrogen. Oxygen is present in water along with hydrogen so it has two hydrogen bonds per molecule in it.
2.... Its again E) Lymphatic System
Lymphatic system transports the ejected tissue sap from all over the body to the blood. And along with it fats from the gastrointestinal cavity are also transported through the Lacteals into the cardiovascular system. Lacteals are lymphatic vessels present in the villi of intestines.
3.... Its A) Denatured..
Proteins are always denatured when the environment is not favorable. The word denatured refers to the transfer of shape and function from normal to abnormal condition which is anti parallel to the nature of proteins.
4.... Its again A) Glucose
Its the most concentrated source of energy because ATPs are directly produced from glucose molecules in the body.

3. A
4. E
If glucose is there, body uses glucose. But fat is the concentrated form. It is in the dehydrated form and provide more energy than glucose.
