A medium that works by showing two reaction types is called a differential medium
<h3>Differential media</h3>
Differentia media are one of the numerous culture media used in culturing microorganisms. They are also known as indicator media.
They are called differential media because they are able to make a distinction between two microorganisms growing on them based on the biochemical characteristics of some organisms in the presence of certain indicators or nutrients.

Answer:
d.A substance with a density of less than 1.00 g/mL.
Explanation:
The density of water, or of any fluid in which you immerse yourself, is directly proportional to the upward force that this fluid will exert on you. That is, the denser the water, the more you can float on it. This is the principle of Archimedes, with his famous Eureka.
In relation to the buoyancy of bodies, it does not depend only on the density of water, or fluid. Buoyancy also depends on the weight / volume of the body being submerged. In this case we are going to focus on the density of water / fluid.
In the case of water in conditions of temperature at 25 ° C the density is usually 1 g / ml so that any object that has a density less than it can float in it.
Answer:
1. A
2. B
Explanation:
1. Most of the answers don't make that much sense, so using process of elimination I resulted in this answer. I recommend you also try to check with others.
2. This question also was pretty confusing but when using process of elimination I resulted in either A or B. To me B makes more sense.
When the temperature rises some materials experience thermal expansion which means they get bigger, so it may make them harder to close because they don't fit as well.
Freezing the substance and condensing it will not increase the entropy of a substance. In fact, dissolving the substance into water is the only way to increase the entropy of a certain substance. The entropy increases because it diversify with each other.
