The characteristics of agar that makes it a useful solidifying agent for growth media is it is unable to be metabolized by most microorganisms. Agar is a common solidifying agent for a culture medium; a complex polysaccharide derived from a marine alga - long been used as a thickener in foods such as jellies and ice cream. Agar has some very important properties that make it valuable to microbiology, and no satisfactory substitute has ever been found. A small number of microorganisms can damage agar so it remains solid. Also, agar liquefies at about 100°C which is the boiling point of water and at sea level remains liquid until the temperature drops to about 40°C. For laboratory use, agar is held in water baths at about 50°C. At this temperature, it does not injure most bacteria when it is poured over them. As soon as the agar has hardened it can be keep warm at high temperature approaching 100°C before it again dissolves and is particularly valuable when thermophilic bacteria are grownup.
Answer:
This is not the best practice because the fever is a mechanism of the body against infection since it will raise the body temperature bacteria, which live well below 37 ° C, die, however it is noteworthy that by itself the fiber can not cure an infection but defenses are needed and must be treated with antibiotics.
In addition, in a small percentage of cases the fever becomes urgent. This is true. It is only true if it exceeds 42 ° C in a sustained manner.
Answer:
Silent mutations are mutations in DNA that do not have an observable effect on the organism's phenotype. They are a specific type of neutral mutation. The phrase silent mutation is often used interchangeably with the phrase synonymous mutation; however, synonymous mutations are not always silent, nor vice versa.
Answer: Motion
Explanation:
Its motion becuase kinetic energy is movement/motion since it moves its balance
