The kinetic energy of an object depends on both its mass and its speed. Kinetic energy increased as mass and speed are increased.

Options:
A. The enzyme lactase will speed up the breakdown of lactose in the small intestines.
B. Reactions that involve enzymes require more energy than reactions without enzymes.
C. The enzyme lactase will slow down the breakdown of lactose in the small intestines.
D. Lactase will require more energy to break down lactose, and less energy is required if it is not present.
Answer:
A. The enzyme lactase will speed up the breakdown of lactose in the small intestines.
Explanation:
A. The enzyme lactase will speed up the breakdown of lactose in the small intestines. - this is true. Lactase is an enzyme that catalyses the breakdown of lactose. This means it greatly reduces the activation energy required for the breakdown of lactose, and the reaction will happen quicker.
B. Reactions that involve enzymes require more energy than reactions without enzymes. This is false. Reactions that involve enzymes require less energy that reactions without
C. The enzyme lactase will slow down the breakdown of lactose in the small intestines. This is false. It will speed it up
D. Lactase will require more energy to break down lactose, and less energy is required if it is not present. This is false, more energy is required if it is not present
Answer:
A: Draw conclusions about their data.
Explanation:
A important step in the scientific methodology, once the results are analyzed is to draw reasonable conclusions about the whole experiment. For example: if a scientist has studied the effect of salt stress on the growth of plants and he got the results in form of graphs which show that growth of salt treated plants in very less than normal plants. Then he needs to draw conclusion after consulting relevant previous experiments and say that salt stress hinders growth and why? with reasonable logic. This is an important step in the scientific methods which concludes our work and makes it more impact for the upcoming scientists interested to work on problems of similar nature.
Hope it helps!
