Answer:
I remember back in high school I conducted an experiment involving two Petri-dishes. Both had swabs from my kitchen sink (a lot of bacteria). The difference was that I used Lysol versus Clorox.
Explanation:
You can start here. Secondly, formulate a good hypothesis and test it. For example, you can say I believe Lysol works better than "X-Brand" or "Y-Brand".
Then list the results.
I hope this helps.
The concentration expressed in parts per million is 782 ppm.
<h3>What is Parts per million?</h3>
It is calculated by dividing the mass of the solution by the mass of a solute present in one million (10⁶) parts.
<h3>Calculation for units in ppm:</h3>
Given:
Mass of blood alcohol = 80 mg/dL = 80 x 
g/mL
Density of blood plasma or Mass of blood plasma = 1.023 g/mL
Concentration in ppm = (Mass of alcohol/Mass of plasma) x 
= (80 x g/mL/ 1.023 g/mL) x
= 782 ppm
Hence, the concentration expressed in parts per million is 782 ppm.

Answer: Option A "Loss of body fluids"
Explanation:
When the body lose blood or other fluids from the body, then the amount of blood in the body is reduced. The Hypovolemic shock happens when a sudden loss of body fluids takes place which is extremely dangerous.
Example:
At the time of delivery, there is blood loss from the body. At the time of injury there is a loss of blood from the body. These processes leads to loss of blood and body fluids.
