<h2>Hello!</h2>
A sustainable practice is B. Setting usage limits on a resource
<h2>Why? </h2>
Sustainable practices are those that aim to reach an equilibrium between the use of natural resources for human development, and the preservation of the environment for future generations.
Setting usage limits on a resource is a sustainable practice because it allows for taking advantage of the resource, while providing constraints to its use, forcing the industry to be creative and develop alternative methods that take better advantage of that resource, or that use different resources (e.g. limiting fossil fuel emissions, forcing the industry to find alternative ways to generate power like solar energy).
Have a nice day!

The answer for the first question is A. Iced Tea and C. Orange Juice. The answer for the second question is A. Heterogeneous mixture
A homogeneous mixture is a combination of 2 or more substances wherein its concentration is evenly distributed throughout the mixture. This means that you cannot identify the different components or properties of the mixture. A heterogeneous mixture, on the other hand, is a combination of 2 or more substances wherein its components are unevenly distributed. This means that its components can visibly be identified from each other.
Answer:
It is basically a way of telling you how to solve for different variables in the equation d=m/v
Explanation:
Answer:
5 ppb of Cd
Explanation:
Given , Concentration = 0.0050 mg/L
To find this concentration in parts per billion
As,
1 mg per liter = 1 ppm
Parts per billion is defined as the number of the units of the mass of contaminant per thousand million units of the total mass. The relation between ppm and ppb is shown below as:
1 ppm = 1000 ppb
Concluding as:
1 mg per liter = 1000 ppb
So,
0.0050 mg/L = 1000 × 0.0050 ppb = 5 ppb of Cd
