Answer:
The correct answer would be - mycobacterium, and streptomyces.
Explanation:
Actinobacteria is a phylum that consists of a group of gram-positive bacteria with cytosine and guanine content in their DNA. These bacteria can be aquatic or land bacteria. Actinobacteria do not have cell wall however they make a non-sptate and mycelium.
Mycobacterium is one of the genera of the actinobacterium phylum. This genus includes pathogenic species in it that cause deadly diseases in humans and other mammals such as leprosy and tuberculosis Whereas streptomyces is another genus of the actinobacteria that is yielded the very first drug to fight with the ancient scourge.
Thus, the correct answer is - mycobacterium and streptomyces.
I would go with the first option
Cochlea.
The part of the ear where sound wave compressions and rarefactions cause the eardrum to vibrate is the middle ear. The 8th nerve in the inner ear actually converts the mechanical energy to electrical energy for transmitting to the brain. A membrane called the tympanic membrane separates the middle ear from the outer ear. Whenever a sound reaches the ear, it creates a sound wave that creates vibration in the eardrum. The pressure when high pushes the membrane inwards while low pressure sound waves helps the eardrum to come outwards. <span>
These sound waves are then transduced when it reaches the cochlea where hair-like structures interprets the sensory information and is relayed to the brain.</span>
