Answer: b
An inherited modification of structure or function that allows an organism to survive and reproduce in its environment.
Explanation:
Adaptation helps an organism to become better suited to survive and reproduce in its environment. It is change in an organism's structure or behavior.
Change in physical features of an organism is considered as structural adaptation. Example- fur in bear
Change in the way an organism does things to survive is called behavioral adaptation. Example- bird calls and migration from one place to another.
Adaptation is an essential feature that helps an organism to better servive in the environment. In case, an organism fails to adapt to changes in its environment, its immune system becomes weak and fails to work. This threatens its life and it becomes ill. This may also result in its death.

Explanation:
Sound waves enter the OUTER EAR and travel through a narrow way up to the eardrum, where it vibrates.
The vibrations are sent to the bones of the MIDDLE EAR where they are amplified, and passed to a structure called COCHLEA in the INNER EAR.
Finally, it reaches the sensory cells that passes it to the auditory nerve that transmit the sound to the brain as electrical signals (neural messages) for proper interpretation.
So, it is True because from OUTER EAR to MIDDLE EAR, to INNER EAR.
lemon juice is 100 times as acidic as tomato juice. remember, each step in the pH scale represents a change in concentration by a factor of 10. since tomato juice has a pH of 4.0, and lemon juice has a pH of 2.0, the concentration would change by 10 times 10.
