decrease resource use
Explanation:
A decrease resource use is one method that might be used to decrease the rate of approach to carrying capacity by the developed world.
A carrying capacity is the amount of people a particular place can sustain.
- Resources available in a place plays a very central role in determining the carrying capacity of a place.
- Resource availability limits population to a large extent.
- Developed nations are resource based systems.
- If there is a decrease in how resources are used, it can lead to scarcity of certain products that are in need.

Answer:
525 grams
Explanation:
Assuming the solution to be prepared is 15% by weight calcium chloride, it means 15 grams of calcium chloride will be in 100 mL of solution.
To calculate the amount needed to make 3500 mL solution;
15 g is required to make 100 mL
X g is required to make 3500 mL
X = 15 x 3500/100
= 525 g
<em>Therefore, 525 grams of calcium chloride will be needed to make 15%, 3500 mL of calcium chloride solution.</em>
