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.
Mitosis occur more fast in our body. It can also meiosis occurs more in men than in women, and they splits once as meosis splits twice and they are not identical.
