and took away his hand quickly. Can
you recognize the tissue and its type
responsible for it?
​

Answer 1

Answer:

C

The ear pinna has yellow/elastic cartilage which is very flexible while the nose tip has hyaline cartilage which is not that flexible.

D

The tissue responsible for it must be the nervous tissue,muscular tissue and the epithelial tissues of the hand. The heat receptors in the epithelia of hand sensed heat and the nervous tissue coordinated these signals to withdraw the hand while the muscles contracted so that the hand can be pulled back.
