That would be the mitochondria. They produce the energy needed for activities that occur in the cell, thus its being called the "powerhouse of the cell"
Answer:
It turns plain water into hydrogen peroxide, not sure about the bonding procedure.
Explanation:
Catabolic reactions are reactions that break larger molecules down into smaller molecules, and often result in the release of energy as a by product of the bonds being broken. In fact, metabolism (the breakdown of food) is a catabolic reaction.
So the best answer would be the Answer no.4:
A => B + C + Energy
A new species develops when the two diverging species no longer recognize each other as their potential mates. In such cases, these two species evolve and grow as two completely different species. There is no genetic exchange between these two species now. When two species diverge, there are no chances of of the members of each of them mating as there DNA (Deoxyribonucleic acid) is no longer compatible.
Hence, the correct answer is 'Option A - diverging species no longer recognize one another as potential mates'.
you didn't list choice but i'm guessing chloroplasts
