Answer:

C. Plants converting sunlight into chemical energy.

Explanation:

An "endothermic reaction" is a process whereby <em>energy coming from the surroundings is being absorbed as heat.</em> This activates the reaction to occur.  Since it absorbs the heat to start the reaction, then it can be classified as an endothermic reaction.

When plants convert sunlight into chemical energy, it absorbs the sunlight as a light energy on its chlorophyll. This is where photosynthesis occur. This then results to the chlorophyll reacting with the carbon dioxide, water and the energy which results to the production of <em>oxygen and glucos</em>e.

So, this explains the answer.

Can I get help and an explanation on C?
Diano4ka-milaya [45]

Answer:

1.67 m/s

Explanation:

Momentum is conserved.

Initial momentum = final momentum

(30 kg) (10 m/s) + (35 kg) (-10 m/s) = (30 kg) v + (35 kg) (0 m/s)

300 - 350 = 30v

v = -5/3 m/s

Linus will move at 1.67 m/s in the direction opposite that he started.

The white dwarf that remains when our sun dies will be mostly made of
expeople1 [14]

Answer:

Carbon and oxygen

Explanation:

White dwarfs are the stars which have used all their hydrogen and helium fuel and now exists with only carbon and oxygen in their core. Their size reduces up to one hundredth times of the size of their sun in early stages and yet they possess the same mass.  

Due to loss of fuels and impact of gravity, a young star collapses on itself leading to formation of dwarf star.
