Darwin’s finches show a variety of beaks suited for eating large seeds, flying insects and cactus seeds.

Ancestral seed-eating stock of Darwin’s finches radiated out from South American mainland to different geographical areas of the Galapagos Islands, where they found competitor-free new habitats.

The atmospheric concentration of $C{O}_2$ at which photosynthesis just compensates for respiration is referred to as $C{O}_2$ compensation point.

The $C{O}_2$ compensation point is reached when the amount of $C{O}_2$ uptake is less than that generated through respiration because the level of $C{O}_2$ in the atmosphere is more than that required for achieving $C{O}_2$ compensation point.

The age-sex structure of human population in countries like France and Germany gives a steep pyramid.

In countries like Sudan and India the population is increasing at a rapid rate.

The duck-billed Platypus and the spiny ant-eater, both are egg-laying animals yet they are grouped under mammals.

Both of them have seven cervical vertebrae and 12 pairs of cranial nerves.

$Agrobacterium$ $tumefaciens$ is popular in genetic engineering because this bacterium is associated with the roots of all cereal and pulse crops.

A gene incorporated in the bacterial chromosomal genome gets automatically transferred to the crop with which the bacterium is associated.
