(i) Growth by increases in mass only
(ii) Regeneration
(iii) Self-consciousness
(iv) Anabolism and catabolism
(v) Binary fission

• A. A - (i,ii,iii,iv) B- (i, iii, iv)
• B. A - (ii,iv) B- (iv, v)
• C. A - (ii,iii,iv) B- (i, iv, v)
• D. A - (i,ii) B- (iii, iv, v)

Answer 1

Answer: (B)

A - (ii,iv) B- (iv, v)

Binary Fission:- By this process bacteria reproduce and increase their numbers.

Regeneration:- It is the process by which nematodes can regrow their whole body from e single cell.

Anabolism & Catabolism:- The process in which due to the metabolic activity of cell the dry weight of the cell increases and decreases respectively. on the other hand we can say that the anabolism is a constructive metabolism and catabolism is a destructive metabolism.

muscle growth and annual ring of plant is the example of growth by increases in mass only which increases the body mass of the organism. usually shown in higher organism.

Self-consciousness:- It is a mental state/ state of a mind of a organisms. exclusively found in higher organism whos's brain is well developed.

So, the correct option is 'B'
