Answer:
most likely caused by natural selection in which mosquitoes resistant to DDT could survive and reproduce, while other mosquitoes could not.
Explanation:
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).
There’s allot so then the plasmodesmata connect cells together to facilitate water transport.
