A The hypoglossal nerve is mainly a somatic efferent (motor) nerve to innervate the tongue musculature. The nerve also contains some sympathetic postganglionic fibres from the cervical gangliawhich innervates tongue vessel and some small glands in the oral mucosa.

Tadpole of frog is
1 ammonotelic
2 ureotelic
3 uricotelic
4 none of these
Explanation:
A Tadpoles are ammonotelic because they live in water so that ammonia is excreted through their body and frogs are ureotelic because they live on land and excrete urea.

Cloacal aperture of frog is used to pass out
1 sperm
2 faeces
3 urine
4 all of these
Explanation:
D The ureters act as a urinogenital duct which opens into the cloaca. Cloacal aperture is the opening of the cloaca through this opening urine undigested foodeggsand sperms are passed awayas it is a common passage. It is present in amphibiansbirdsfishes and monotremes.

Different colour of frog skin are controlled by
1 hormones
2 melanocytes
3 nervous system

Explanation:
A Change in colour of skin is produced by expansion of pigment in the melanophores under the influence of hormones of pituitary gland.
