Answer:

-100

Explanation:

If the total water potential in the soil around a plant root were -50 kPa, water would move from the soil into the root if the water potential inside the root cells were -100 kPa.

The water potential of a substance represents the measure of potential energy in water molecules in a system as compared to that of pure water. It is also a measure of the tendency of water to move from one region to another.

<em>Usually, water will move from the region of high water potential to the region of low water potential. Hence, for water to move from the soil into the root, the root must have a lower water potential than the soil.</em>

The soil had -50 kPa water potential, hence the only option that is lower than -50 kPa is -100.

The correct answer is -100 kPa.

DiKsa [7]
In biochemistry, enzymes are protein catalysts of the body that speeds up certain specific metabolic reactions in the body. They word in the concept of lock-and-key theory or induced fitting. These two theories are all based on the shape and size of the enzyme's active site that could accommodate the substrate. So, the main function of the enzyme is dependent on its shape. Therefore, when an enzyme undergoes denaturation, its orientation and shape changes. For example, a beta pleated sheet may change to an alpha helix orientation. As a consequence, the number and capacity of active sites changes. Hence, the enzyme becomes nonfunctional.
