Why is it important to study the theory of plate tectonics and continental drift?
Dvinal [7]
It is practical knowledge in the sense that we know why some parts of the world are inherently risky to live in. Even though volcanic eruptionis, earthquakes and tsunamis are difficult to predict, it makes sense to have building codes and emergency plans that take this into account.

It is science’s response to the beliefs that natural catastrophes (volcanism, earthquakes and tsunamis) are divine punishments for the evil ways of some individuals.

Even if you will never use or apply this knowledge, knowing about the theory of plate tectonics gives you a current scientific perspective on what we know about the natural world.

It is a good example of how scientific theories proceed by trying to fit several observations into a coherent explanation.

Learning about the observations that needed to be made and explained for the theory to win over scientists helps caution you against people who adopt belief systems without questioning the myths told to them, or those who try to profit from ignorance of how nature actually works.

When it is well taught, it should convince you that, like any scientific theory, plate tectonics is a “work in progress”. New discoveries continue to be made, and it takes creative and logical thinking, debate and a quest for more observations in order to determine which ones prove or challenge the current theory and which ones may lead to its refinement.

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
