True

True Scientists may engage in different activities in different sequences because the work of the scientists is to invent new thing.

Explanation:

For that they have to search many concepts and they not only depend on only one concept. So the scientists have to engage with different concepts to invent one thing.

Moreover scientists must have a knowledge on wide range of subjects. Because new invention means finding something that never exists. We will find new thing by using the existing concepts only.

So the scientists must have idea in different activities in different sequences.

false br

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.
