Answer:
b) The roots grow towards the force of gravity and the stem goes away
Explanation:
The parts of a plant can be divided into shoot and roots. The root of the plant is the part that grows below the ground surface in order to anchor the plant. When a seed germinates, the root part of that seed grows towards GRAVITY i.e exhibits geotropism while the shoot part grows away from gravity i.e. upwards.
Hence, if a seed is planted upside down, it will still grow into an erect mature plant because THE ROOT WILL ALWAYS GROW DOWNWARDS IN RESPONSE TO GRAVITY (positive geotropism) while the stem grows upward away from gravity (negative geotropism)

The doppler effect, when used with light, produces a shift of frequencies to red. Well, no matter which direction you look, there is a shift to red! That means that the universe is expanding or moving away from us in every direction. The idea, is that this could only happen if all matter was once in a single point, and there was an explosion. This explosion from a single point is called the big bang theory.
A nebula is a cloud of gases that can coagulate to become a new star.
