Answer:
B
Explanation:
The Ames test is a bacteriological technique commonly used to determine if a particular chemical or substance can cause mutations. To achieve this, researchers use bacteria (commonly <em>Salmonella typhimurium</em>) as this bacteria strain is unable to grow in a medium that does not contain histidine (a very important amino acid in the biosynthesis of proteins). If the studied substance is able to cause mutations, bacteria will mutate, and they will be able to grow on that particular media even if they don’t have histidine for their metabolism. Therefore, if there are colonies growing, the chemical being tested is mutagenic.
I hope this clarify your inquiry.
Answer:
I can't think of any advantages to knowing your score.
Disadvantages of knowing your score - You're most likely to be average statistically...but does that matter? It doesn't tell you what you can or can't do, how successful you'll be, or what you'll face in the future. The total IQ score isn't really informative regarding almost anything. The exam is frequently used in clinical settings to assess areas of disability, competency, and so on...
