Answer:
B
Explanation:
The distance of the Goldilocks zone ensures that water on the terrestrial planet is maintained in the liquid phase. This is because the distance from the star ensure it receives enough sunlight to keep the planet warm but not too hot that the water exists as vapor. Water in its liquid form is essential for maintaining life like here on earth.
Answer:
No atoms are created or destroyed in chemical reactions.
Explanation:
Matter cannot be created or destroyed. When two reactants contact each other, a chemical reaction occurs which breaks the bonds between atoms and rearranges them, forming new bonds which transform them into the product. The same amount of atoms exists before and after the reaction.
The enzymes are the special types of proteins which decreases the activation energy of the chemical reaction. The activation energy is the minimum amount of energy required to start a chemical reaction. Hence the enzymes are the special type of proteins that catalyses or speed up the chemical reaction by decreasing the activation energy of the reaction. Hence the correct answer is option C. Enzymes.
