A gyrus is a ridge or fold between two clefts on the human cortex.
Answer:
Part A: False
Part B: Liver enzymes may activate some innocuous compounds, making them mutagenic
Explanation:
The Ames test, also known as <em>Salmonella typhimurium</em> reverse mutation assay, is a bacterial short-term technique used to identify if a particular chemical compound may cause mutations in target cells. It has been shown that there exists a positive correlation between carcinogenicity and mutagenicity in the Ames test, but this correlation is not absolute. In the Ames test, a rat liver homogenate (containing liver enzymes) can be added in order to identify substances that are not mutagenic themselves but are metabolized in order to form a mutagen (e.g., benzopyrene).
It should be C., as an ecosystem has both biotic and abiotic factors.
