Question

What happens to the strength of all fields as the distance from their sources increases?
It decreases
It increases
It becomes unpredictable
D
•It remains constant

Answer 1

The strength of all fields (such as gravitational, electric, and magnetic fields) generally decreases with increasing distance from their sources. Therefore, the correct answer is:

**It decreases**.

For example, the gravitational field strength decreases with the square of the distance from the mass creating it, and the electric field strength also diminishes with distance according to similar principles.

Answer 3

To identify the components mentioned in your request, considering a typical reaction involving starch conversion leads to maltose (and ultimately glucose), we can identify them as follows:

1. **Substrate**: Starch (the substance being acted upon)
2. **Enzyme**: Amylase (the enzyme that catalyzes the breakdown of starch into maltose)
3. **Product**: Maltose (the product formed from the breakdown of starch by amylase)

If your analysis was extended to the complete reaction, maltase would come into play later in the process to break down maltose into glucose:

4. **Substrate**: Maltose (when considering the next stage where maltase acts)
5. **Enzyme**: Maltase (the enzyme that catalyzes the breakdown of maltose into glucose)
6. **Product**: Glucose (the final product after maltose is broken down)

However, if you are specifically focusing on the first half of the reaction (starch to maltose), the identification would primarily encompass starch, amylase, and maltose as the substrate, enzyme, and product, respectively.
