Answer:
<em>DNA </em><em>can </em><em>be </em><em>used</em><em> </em><em>to </em><em>tell </em><em>people</em><em> </em><em>apart </em><em>because</em><em> </em><em>humans </em><em>differ </em><em>from </em><em>each</em><em> </em><em>other</em><em> </em><em>based </em><em>on </em><em>either</em><em> </em><em>their</em><em> </em><em>DNA </em><em>sequences</em><em> </em><em>or </em><em>the </em><em>lengths </em><em>of </em><em>repeated</em><em> </em><em>regions </em><em>of </em><em>DNA.</em><em> </em><em>Length</em><em> </em><em>difference</em><em> </em><em>are </em><em>typically</em><em> </em><em>used </em><em>in </em><em>forensics </em><em>and </em><em>paternity </em><em>testing</em><em>.</em>
Answer;
-The rate of the reaction;
The presence of an enzyme affects only the rate of the reaction.
Explanation;
-Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
-Additionally, the rate of a chemical reaction increases as the substrate concentration increases. Enzymes can greatly speed up the rate of a reaction. However, enzymes become saturated when the substrate concentration is high.
A. The net force applied will increase.
This is an example of Newton's second law that says that you will need more force to move an object of a lot of mass. F = m×a; F=Force= M= Mass×A= Acceleration
