Ig it’s true. The emission of gramma rays results in the loss of energy.
Animals that live in any snowbound region may adapt to its environment by growing bigger feet in order to be able to walk over the deep snow. Also the animals might grow thicker fur in order to keep the animal warm while in the cold weather.
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

The right answer is 1/4.
Two carriers of the disease each have a chance in two to transmit their sick gene ie: 1/2 * 1/2 = 1/4
A genetic disease is said to be autosomal recessive when
The gene involved is carried by an autosome (non-sex chromosome, X or Y in XY system of sexual determination);
The associated phenotype of this trait is recessive (the presence of two identical alleles is essential for the character to be expressed).
One of the two alleles is transmitted by the male gamete, the other by the female gamete.
But being a carrier of the mutation does not necessarily mean being sick, the manifestations of a genetic disease depend on its penetrance and the variability of its expression.
