The membranes of chill sensitive plants have been found to have about a 2:1 ratio of unsaturated to saturated fatty acids. It has been seen that the proportion of unsaturated membrane fatty acids increases and the critical temperature decreases when chill-sensitive plants are acclimated to a low temperature.

Correct Option: D

the environmental lapse rate is greater than – 5.5 K/km, then there is some small amount of vertical turbulence and the atmosphere is said to be stable. It is also referred to as being sub-adiabatic.

The Gambusia fish, also known as mosquitofish, feeds on the larvae of mosquitoes. So it helps in controlling their population. Mosquitofish were introduced directly into ecosystems in many parts of the world as a bio-control to lower mosquito populations which in turn negatively affected many other species in each distinct bioregion.
