Ah me, 80 points in each example, the atmosphere is interacting with another subsystem of earth. identify the other subsystem. water evaporates in the presence of sunlight. volcanoes release a large amount of gases and other matter during eruption. lightning causes nitrogen molecules to be split and carried by rain. plants release water vapor through their leaves during transpiration.

1.Water evaporates in the presence of sunlight.

(hydrosphere)

2.Volcanoes release a large amount of gases and other matter during eruption.  

(lithosphere)

3.Lightning causes nitrogen molecules to be split and carried by rain.

(hydrosphere)

4.Plants release water vapor through their leaves during transpiration.

(biosphere)

Hope this helps!

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
