Which are of the following sets of characters are applicable in metamorphosis of tadpole larva of frog and toads?
1 Reabsorption of gills and lengthening of tail
2 Complex development of gill and lengthening of tail
3 Reabsorption of gills and resorption of tail
4 Complex development of gill and resorption of tail
Explanation:
C The process of transformation of larva of some vertebrates and majority of invertebrates into adult is called metamorphosis. Reabsorption of gills and resorption of tail are the characters applicable in metamorphosis of tadpole larva of frog and toads.

How can a tadpole be prevented to change into frog for long time?
1 By giving very less food
2 By giving fat-rich food
3 By adding lot of thyroxine to the water in which they are kept
4 Provide them an antithyroid substance like thiourea
Explanation:
D The anti thyroid drug like thiourea reduces the secretion of thyroxin hormoneswhich prevents metamorphosis of frogbecause during metamorphosis thyroxin hormones change a tadpole into mature frog.

The third cleavage of frogs egg is of:
1 transverse and equal type
2 vertical and equal type
3 transverse and unequal type
4 vertical and unequal type
Explanation:
C Cleavage is the series of mitotic divisions that divides an embryo after fertilization. The first cleavage occurs shortly after the zygote nucleus form. The third cleavage of frog egg is transverse and unequal type.
