The following are the answers to the above questions.
Q.35 : option B, the answer is self explanatory.
Q.36: option B, The nucleoli is multiple for nucleolus which is the largest subunit of nucleus,it's major function is ribosome biogenesis.
Q.37: option C, The minimum amount of energy required for a chemical reaction to start between two potential reactants is called activation energy.It is denoted by Ea and measured in units of kilojoules/ mole (kJ/mol) or kilocalories/ moles( kcal/mol).
Q.38: Option B, The channels are called voltage gated channels mainly Calcium channels.
Q.39: Option C, the delicate unpigmented hairs that cover the fetus are called lanugo hairs.
