Ed has two citrus trees at his home. he keeps one outside on a shaded patio, and the other indoors near a large window and a lamp. the indoor tree receives more light and experiences more stable temperatures than the outdoor tree.

he noticed that the indoor tree grew faster and produced bigger oranges than the outdoor tree. he installed a grow-lamp near the outdoor tree so that it would receive as much light as the indoor tree, but there was no change: the indoor tree continued to outgrow the outdoor tree.

based on this investigation, what would be the next logical question that ed should address?

lol

explanation:

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
