What your cells have to help overcome a problem of high activation energy are called enzymes. Enzymes are proteins that lower the activation energy of a reaction. In doing this, enzymes increase the rate of a reaction, helping it to occur faster. However, enzymes are not consumed in a reaction; they simply help it to occur.
Enzymes make things easier for your cells to work properly and help chemical reactions occur. There are hundreds of different kinds of enzymes in your cells, which all participate in different types of reactions. Enzymes can break molecules apart, build or add molecules, and even rearrange them.
In lowering the activation energy of a reaction, enzymes decrease the barrier to starting a reaction. It's important to note, however, that the change in energy remains the same between the start and end of a chemical reaction.
Answer:
B
Explanation:
As the moon rotates around the Earth the angle of light given off from the sun changes.
Think about the actual physical process happening in the cell - the allele (or versions of a gene) are literally physical pieces of DNA strung together into chromosomes. And as the cell divides to form gametes, those chromosomes randomly assort themselves into the two new cells (conditional that each new cell gets one copy of each chromosome, in the case of gametes)...<span>
