Answer:
The correct answer is: common ancestor
Explanation:
Hello! Let's solve this!
According to the evolution of living beings, we all have an ancestor.
Depending on the branch in which the living being is, it unites with the ancestor of another.
Two different branches that never join, do not have a common ancestor. In this case, they have a characteristic that unites them, so whales and pythons have a common ancestor.
The correct answer is: common ancestor
B.) the activation energy
C.)
D.) the concentration of reactants
Answer:
The correct answer is option B.) "the activation energy".
Explanation:
In chemistry, a catalyst is defined as a substance that accelerates a chemical reaction without being consumed in the reaction. Catalysts affect the activation of energy of the reaction by lowering it. This happens because catalysts open new pathways of reaction that require less energy, therefore the alternative routes need lowered activation energy for the reaction to start.
