role of water in biology

Almost 70% of water you take, becomes the part of your body which doesn’t happen with any other consumable. Preliminary evolution has taken place in water making your entire chemistry revolving around water chemistry and aqueous solution. There are no many biological academic  resources which provide biology questions  and multiple choice questions for practice. 

@planetbiologia you get series of quality questions based on primary and advanced level of understanding the biological science. Many important topics like pH, membrane transport, physiology etc. are related to different chemical and physical properties of water. 

Use this question set for advanced level MCQs. We provide the additional type of quiz i.e. picture quiz to test the actual level of understanding of the subject. 

1. 
Great internal cohesion on liquid water is because of the….

2. 
Which of the following properties of water can be attributed to hydrogen bonding?

3. 
Which of the following is not the strategy to transport the insoluble gases into the biological system

4. 
Observe the following molecular structure and choose one the following that explains the difference between the boiling point of the molecules.

CH3CH2CH2CH2CH3 b.p. -0.5◦ C

CH3CH2CH2CH2OH   b.p. 117◦ C

5. 
Choose the correct mechanism of dissolving a salt in water?
