Hydrogen fuel cell powered cars emit a 0 emission.
The mechanisms of reproductive isolation prevent the reproduction of two individuals from different species. The prezygotic mechanisms disrupt the stages of reproduction before the forming of the zygote or prevent the mating at the start, and the postzygotic mechanisms affect the stages of reproduction after the forming of the zygote.
So, the first and the third example (the urchins and the grasshoppers) show the prezygotic mechanism, as the two individuals are not able to mate or form a zygote.
The second and the fourth example ( zonkey and the death of a zygote) show the working of the postzygotic mechanisms, as the zygote is formed, but it seems to be inviable, and the zonkeys are sterile, preventing the individual to reproduce.

D acceleration is the answer
Answer:
Due to strong forces between solutes and solvent, solubility increases.
Explanation:
Due to intermolecular forces, RNA solubility is higher than the solubility of proteins and lipids because intermolecular forces enables RNA soluble in water due to its polar nature while on the other hand, proteins and lipids are not very soluble in water due to their non-polar nature. If the intermolecular forces are stronger between solute and solvent molecule, the greater the solubility of the solute in the solvent and vice versa.
