Adisease-resistant variety of a sexually reproducing crop was planted on a field with an existing nonresistant variety. after a few years, pests severely attacked the plants. the older, nonresistant plants died. however, the recently grown plants survived. why did the new plants survive?

Achemical equilibrium between gaseous reactants and products is shown. n2(g) + 3h2(g) ⇌ 2nh3(g) how will the reaction be affected if the pressure on the system is increased? it will shift toward the reactant side as there is lower pressure on the reactant side. it will shift toward the product side as there is higher pressure on the product side. it will shift toward the reactant side as there are a greater number of moles of gas on the reactant side. it will shift toward the product side as there are a fewer number of moles of gas on the product side.
