Answer: Choice D
Explanation: Natural selection explains how the strong survive due to mutations to suit the environment.
Answer:
go down on the first one the go to middle on second tay it that way
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>
Answer:
c.The lac genes would be expressed continuously.
Explanation:
The <u>correct response is (c)</u> The lac genes would be expressed continuously because the active repressor cannot bind to the mutant O c operator. Accordingly, the repressor will not be able to inhibit RNA polymerase from binding to the lac promoter, producing the lac operon to be transcribed continuously or constitutively. Formerly again the level of appearance is inversely proportionate to the level of glucose already present.
