Explanation / Answer

1 B. Ganglion cells :- Ganglion cells layer of retina contains axons of bipolar cells, and their axons forms the optic nerve

2 C) Cristal ampullares :-The receptors for dynamic equilibrium are found in the crista ampullaris of the semicircular canals.

3 A) a system of motor neurone that inner ages smooth and cardiac muscle and glands:- Autonomous nervous system ANS is a part of peripheral nervous system and mainly control fight-or-flight Mechanism.

4 E) umami - triglycerides and fatty acids :- umami has taste of amino acid L-glutamate.

5 D) absence of green or red cones in their foveae centralis
