Hope that helps!!!!
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.
The answer is hyperosmotic urine.
A counter current mechanism system refers to a process, which spends energy to produce a concentration gradient. It is witnessed broadly in nature and mainly in mammalian organs. For example, it can signify towards the process of urine concentration, that is, the generation of hyperosmotic urine.
The hyperosmotic urine exhibit greater osmolarity in comparison to the blood. The kidneys generate hyperosmotic urine in response to a deficiency of water as an effort to return to homeostasis.
While it is a common belief to people in the ancient civilisations that the Earth is considered as "flat", the contrary idea that the Earth could be considered as "spherical" was first theorised by the famous ancient philosopher Aristotle when he observed that a circular shadow was cast by the moon during a lunar eclipse.
