Which of the following are likely to be present in deep sea water?

A Blue-green algae
B Saprophytic fungi
C Archaebacteria
D Eubacteria

Verified Solution

Answer & Solution

Correct Answer

(C) Archaebacteria

Step-by-step Solution

Detailed explanation

(c) : Archaebacteria belong to a group of prokaryotic organisms called Monera. These include the methanogens, which produce methane? the thermoacidophilic bacteria, which live in extremely hot and acidic environments (such as hot springs)? and the halophilic bacteria, which can only function at high salt concentrations and are abundant in the world’s oceans.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.

Given below are two statements : one is labelled as Assertion (A), and the other is labelled as Reason (R).
Assertion (A) : The primary function of the Golgi apparatus is to package the materials made by the endoplasmic reticulum and deliver it to intracellular targets and outside the cell.
Reason (R) : Vesicles containing materials made by the endoplasmic reticulum fuse with the cis face of the Golgi apparatus, and they are modified and released from the trans face of the Golgi apparatus.
In the light of the above statements, choose the correct answer from the options given below :
