A: Similarities in proteins and genes performing a given function among diverse organisms give clue to coomon ancestry.
R: All the group of vertebrates arises from the common ancestor with great adaptation capability.

[A]: Homologous organs are similar in basic structure and embryonic origin, but serve different functions. [R]: Similarity in basic structure points to common ancestry whereas diversity in function reflects adaptation to different modes of life.

When two or more organs perform a common function by their physical or chemical interaction that together form an organ system. d. The organ stomach in humans has all four types of tissues. How many above statements are correct?

Read the following statements carefully and select the appropriate option given below. (i) Reproduction is defined as a biological process in which an organism gives rise to the young ones (offspring) similar to itself. (ii) Adventitious buds arise from the notches present at margins of leaves of Bryophyllum. (iii) Asexual reproduction is common among single celled organisms, and in plants and animals with relatively simple organisations. (iv) A few plants exhibit unusual flowering phenomenon, some of them such as bamboo species flower only once in their life time, generally after 50-100 years. (v) The events of asexual reproduction though elaborate and complex, follow a regular sequence.
