Q4. Instantaneous acceleration is defined as
Answer : Option B
Explaination / Solution:
instantaneous acceleration is measured over a "short" time interval. The word short in this context means infinitely small or infinitesimal — having no duration or extent whatsoever.
It's a mathematical ideal that can can only be realized as a limit. The limit of a rate as the denominator approaches zero is called a derivative.
Instantaneous acceleration is then the limit of average acceleration as the time interval approaches zero — or alternatively, acceleration is the derivative of velocity.
Q5. Speed of Sound is given by where
Answer : Option B

Q7. ABO blood groups in humans are controlled by the gene I. It has three alleles - IA, IB and i . Since there are 3 different alleles, six different genotypes are possible. How many phenotypes occur?
Answer : Option D
Explaination / Solution:
The three alleles - IA, IB and i will form four different kinds of blood group A, B, AB and O. as IA and IB are dominant and i is recessive in nature.
Q8. In animal cells, the first stage of glucose break down is
Answer : Option A
Explaination / Solution:
In animal cells, like muscles during exercise, when oxygen is inadequate for cellular respiration pyruvic acid is reduced to lactic acid by lactate dehydrogenase. The reducing agent is NADH+ and H+ which is reoxidised to NAD+ in both the processes.
Q9. The layer of heart pericardium which checks its overstretching and overfilling as well as also protects heart from mechanical injury is :
Answer : Option C
Explaination / Solution:
Pericardium is protective covering of heart. Pericardium is made of different layers to perform different functions. The layer of heart pericardium which checks its overstretching and overfilling as well as protects heart from mechanical injury is fibrous pericardium.
