Can somebody plz answer a. b.c (just make it 1 sentence for each) Not too difficult (WILL MARK AS BRAINLIEST/COMMENT/FOLLOW/
:D Thx guys.

One sentence that can be written for evidence is:

Fossils. Fossils document the existence of now-extinct past species that are related to present-day species.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
