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. 
What is dipole?

2. 
Which of the following the most abundant component of the living system?

Majority of glucose oxidation is involved in ATP synthesis through oxidative phosphorylation and ATP synthase complex. The multiple choice questions (MCQ) is good way to test the level of understanding of the glucose oxidation and energy metabolism. Different biological questions needs to be practiced to strengthen your academic profile.
