Answer:
So 1 ml=1 cm^3, so 40ml is 40 cm^3
D= m/v
density = 30/40
Density of oil is 0.75 g/cm^3 (which is verified as oil is less dense than water hence floats on it)
Explanation:
The cell membranes begin to come apart when there is insufficient water around the cells. The cytoplasm of the cells becomes more concentrated, which slowly poisons the cells. The cell walls become brittle as they dry out, and some of them collapse. The central vacuoles in the cells lose water and can no longer help support the cells.

Difference threshold is a minimum alteration in sensory intensity that is noticeable to an observer and can be coded into neural messages. Different threshold is the lowest level of encouragement that is essential to sense that a modification has happened the difference in the intensity between two stimuli that is necessary to yield a just notable difference also known as JND. The just notable difference depends not only on the intensity of the new stimulus but also on the level of stimulation already present which is the more intense the existing stimulus the larger the change must be to be noticeable.
