Q1. Glycolysis occurs in
Answer : Option A
Explaination / Solution:
Glycolysis" means the splitting of glucose. The first step of the process occurs in the cytoplasm of the cell and yields a small amount of energy (measured in units of ATP) and two molecules of pyruvate.
The other steps occur in the mitochondria.
It is an ongoing process as your cells have a constant need for energy
Q2. Calcium and Magnesium belong to the category of

1-Chloro-4-methyl-2-nitrobenzene is the iupac name of the given compound.
Q5. Magnetic flux (ΦB) through a surface S is given by
Answer : Option D
Explaination / Solution:
if dS is area of an element of any arbitrary shape and magnetic field at this element is B.
The total magnetic flux through the surface is the sum of the contributions from the individual area elements.
Q6. In a general motion of a rigid body
Answer : Option A
Explaination / Solution:
In general motion of the body can be seen as the combination of pure translation of the center of mass and pure rotation of the body about the center of mass like the motion of a wheel.
Q7. In Photoelectric effect
Answer : Option B
Explaination / Solution:
In photoelectric effect emission of photoelectron takes place. So that photocurrent is flow in circuit.
Q8. Which of the following is a possible final step in applying the scientific method
Answer : Option C
Explaination / Solution:
Your experiment tests whether your prediction is accurate and thus your hypothesis is supported or not. It is important for your experiment to be a fair test.
You conduct a fair test by making sure that you change only one factor at a time while keeping all other conditions the same.
You should also repeat your experiments several times to make sure that the first results weren't just an accident.
Q9. The noise level that can cause permanent impairment of hearing ability of human beings :
Answer : Option D
Explaination / Solution:
Noise pollution is a kind of air pollution that may cause permanent impairmentof hearing ability of human beings.
After 150 dB (firecracker) sounds can be felt in the form of shock waves. The pressure difference they cause in the medium can actually be felt by your body. 150 decibels is usually considered enough to burst your eardrums,
Q10. Particles of compounds are
Answer : Option C
Explaination / Solution:
Compounds are made when,
atoms of two or more different elements combine together in fixed ratio to form molecules .(viz. water , ammonia , carbon- di- oxide glucose etc. ) .
Thus the particles of compound consists of molecules.
