Answer 1

Ans 1) Option (a) is correct.

it is a process through which organism that has favourable traits will reproduce more.

Ans 2) Option (d) is correct.

Because there is no importance of differences untill and unless they are inherited by the organism.

Ans 3) The human knee bone and spine were derived from ancestral structures that supported four-legged animals - Anatomical (morphological structure of organism).

The genetic code is the same for all organisms - Biochemical (chemical phenomenon exists in living organism).

The South American continent lacks rabbits, even though the environment is quite suitable - Biogeographical (geographical distribution of plants and animals).

The amino acid sequence of human hemoglobin is more similar to that of rhesus monkeys than to that of mice - Biochemical ( chemical process that take place in living organism).

Ans 4) All 4 choices are correct.

The fossil record will offer direct evidence as with time the ancestory of specific group can easily be traced. Also, common ancestors are also found and we re able to observe the difference in finches of beak size. Thus, we are able to observe the change in fossil type with time.
