Why are the offspring produced by sexual reproduction different than their parents?

offspring create new dna without using their parents’ dna.

offspring create new dna with their parents’ dna as a template.

offspring inherit different amounts of dna from both their parents.

offspring inherit a combination of dna from both their parents.

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.
