Answer:
D
Explanation:
Facilitated diffusion is a form of passive transport hence no energy is required by the cell. This means that while the molecules are moving down a concentration gradient – line normal diffusion – the movement of the molecules needs to be facilitated (in this case by a transmembrane protein) either because the molecule is polar and can't pass through the hydrophobic region of the cell membrane, or the molecule is too big to passively pass through the small natural pores of the cell membrane.
Answer:
Suffling of genetic material increases genetic variation in offspring which is important for evolution.
Explanation:
Genetic shuffling or genetic recombination helps in the formation of new trait combinations which increase the genetic variation in the population and this genetic variation is very much important for the evolution of species.
In sexual reproduction, the genetic shuffling occurs during the formation of gametes when the two homologous chromosomes exchange their genetic material with each other. This increase variation in gametes.
Fusion of two different gametes in sexual reproduction also helps in increasing the genetic variation in the offspring.

Explanation:
For example they have found that it now attacks your kidneys heavily causing failure when in the beginning it did not
