Ice floats on a lake. This characteristic of water is responsible for -

A: suffocation of aquatic organisms
B: mixing a lake's thermal layers
C: altering migration patterns of fish
D: preventing a lake from freezing solid

Option D) preventing a lake from freezing solid

Explanation:

This is based on the difference in density of water in solid form as against it's liquid form

Ice, which is water in solid form is less dense to water as liquid water. Hence, ice floats on liquid water, thereby preventing the total freezing of the lake which would lead to death of aquatic organisms living in polar regions

just here for the other one bc they put up with u

the relative standard reduction potential of the half-cell in which reduction occurs; more positive than the other half-cell. reduction is a chemical process in which electrons are added to an atom or an ion; it always occurs accompanied by oxidation of the reducing agent.
