ANSWERS

S1. Ans (C) Sol. Humification is the process that leads to the accumulation of humus, which is a dark, amorphous, and nutrient-rich substance in the soil.
S2.Ans. (c)
Sol. An antibody molecule is composed of four polypeptide chains: two identical heavy chains and two identical light chains.

S3.
Ans. (d)
Sol. The correct sequence for gel electrophoresis is: DNA fragments move toward the anode (C), they are then stained with ethidium bromide (B), exposed to UV light to be visualized (A), and finally, the desired DNA band is cut out and eluted (D).

S6.Ans. (a)
Sol. The correct sequence of plant evolution from oldest to latest is: Rhynia-type plants (C), followed by Psilophyton (D), then Seed ferns (B), and finally Angiosperms (A).
S7. Ans. (b)
Sol. The correct sequence of products formed during sewage treatment is: Primary sludge (D), which settles out first, followed by the formation of Flocs (C) in the aeration tank, which become Activated sludge (B) after settling, and finally, Biogas (A) is produced from the digestion of the sludge.
