Autonomic nervous system reactivity in humans appears to be inherited.
WORKING DISTANCE is space between the bottom of objective the lens and the surface of the slide.
The distance between front edge of the objective and the lens and the specimen surface ("with the surface of the cover glass in case of the cover glass objective lens") when the specimen is also focused.
The working distance (W.D.) which is determined by the linear measurement of the objective and front lens to the focal plane. In the general, the objective of the working distance decreases by the magnification and the numerical aperture of both increase. The working distance is the distance and from the front of the lens to be the focal plane

Answer:
Option (A).
Explanation:
The element mercury can persist in the environment and proves to be harmful for the living organism. The mercury persist in the lower organism and transfer to the higher organism by the process of biological magnification.
The compounds of methyl mercury are not harmful. The methyl mercury compound cannot cross the blood-brain barrier and does not affect the individual.
Thus, the correct answer is option (A).
