What are the levels of organization of animals from simplest to most complex?

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.

Organisms that live in the alpine and taiga biomes have developed unique adaptations that aid in their survival. moss campion is one of the plants found in the alpine biome. it has small leaves and a cushion shape that protect it from the wind and freezing temperatures in the alpine. how has the moss campion adapted to enable its survival in the alpine biome? a. waxy needles b. cone-shaped c. thin trunks d. low-growing
