What is the main difference between RBCs of human and frog?
1 Human RBCs are non-nucleated
2 Haemoglobin is found only in human RBCs
3 Human RBCs have nucleus
4 Human RBCs are multi-nucleated
Explanation:
A The main difference between human blood cells and frog blood cell is that human red blood cell lack nuclei whereas frog blood cells contain nucleibecause human need more oxygen than frog. - They loss nucleus in order to accommodate more haemoglobinso that they can transport more amount of oxygen.

In an egg of frog is divided in a way that one part has animal hemisphere and another part is deficient in that then:
1 Only animal hemisphere region forms embryo
2 Both the sites form embryo
3 Embryo is not formed from any region
4 Animal hemisphere deficient region forms the embryo
Explanation:
A The egg of amphibians are moderately telolecithal (mesolecithal). This means a large amount of yolk is concentrated at the vegetal pole and the oppositethe animal pole is metabolically more active with radial and holoblastic cleavage. Hencein the animal hemispherethe blastula consists of many small cells with formation of blastocoels that eventually form the embryo and in the vegetal hemisphere fewer but larger cells are present.

Spinal nerves in frog are
1 10 pairs
2 30 pairs
3 12 pairs
4 33 pairs
Explanation:
A Peripheral nervous system of a frog comprises of cranial and spinal nerves. In frog there are 10 pairs of spinal nerves that arise from the side of the spinal cord. Each nerve arises by two rootsa ventral (anterior) and a dorsal (posterior)which unite at their point of exit from the vertebral canal and they emerge between vertebrae.
