Mutation
is random, natural selection isn't random because those mutations which
are most adaptable to the environmental conditions of the time are
those which produce more offspring. I mean, "selection", by definition,
isn't "random". <span>The
clue is in the title. It's not considered random for the simple reason
that it's not random. Natural selection is an extremely deterministic
process. So, i guess it's (D) Natural Selection

Answer: C. Inheritance of acquired characteristics.
Biological evolution refers to the mechanism of slow and steady change in the characteristics of organisms. This takes place over a period of many generations. The primary factors responsible for biological evolution are natural selection, genetic drift, and mutation.
Acquired characteristics are those changes in an organism which occur due to environmental influences. This makes the organisms adapt to the changing environmental conditions.
Inheritance of acquired characteristics means certain characters are passed from one generation to the next generation. This does not result in any change in the population. Thus, the inheritance of acquired characteristics is not a mechanism for biological evolution.
A temperature difference causes particles to move, creating a current. The current transfers heat from areas of high energy to those of lower energy. In gases and plasma, a temperature difference also leads to regions of higher and lower density, where atoms and molecules move to fill in areas of low pressure.
