I am looking for CSIR model/old question paper for life sciences. Where it is available?

Here I am providing the old question paper of life sciences for CSIR NET exam:

doubled and there are favourable conditions of water,
nutrients, light and temperature, what would happen to water
requirement of plants?
(1) It decreases initially for short time and then return to
original value
(2) It increases

mutated organism if a protein had only 70% of the primary
ammo acid sequence, which of the following is likely?
(1) Mutation broke the protein
(2) The organism could not make amino acids
(3) Mutation created a terminator codon
(4)The gene was not transcribed

Q. A reference material is required to be prepared with 4 ppm
calcium. The amount of CaC03 (molecular weight = 100)
required to prepare 1000 g of such a reference material is

(3) 4 mg (4) 10 mg
