Answer 1

-Question 18

In Worses three-kingdom system the three super kingdoms are Archaens, Eukaryotes, Eubacteria.

So the correct answer would be option (4) Cyanobacteria. Except Cyanobacteria all are super kingdoms in Worses three kingdoms system.

-Question 19

The correct option should be option (1) presence of capsule.

-Question 20

The original regimen known as pasturization consisted of:-

Heat at 62.8 degrees Celsius for 30 minutes

So the correct option is option (4)

Question 21-

The answer should be option (4) ribosome

Explanation - In prokaryotes these is no well defined nucleus. In eukaryotes transcription occurs inside the nucleus and translation occurs in cytoplasm. But in prokaryotes both translation ans transcription occurs inside the cytoplasm.

- so here the appropriate answer would be ribosome where the mRNA are decoded into protiens molecules.

Hopefully it helps if problems arises plz comment thanks.
