This test uses prokaryotes which means it isn't a perfect model for humans even after rat liver enzymes are added. Mutagens this test finds might also not be carcinogenic, meaning further tests are required. In addition not all carcinogens are mutagens (such as asbestos) meaning this test won't find them. Finally, some nitrate-containing substances can cause a false positive by production of nitric oxide. An example of this is nitroglycerin which is still widely used in treatment but gives a positive Ames result. Hope this is useful!
phenolphthalein reaction is indicative of blood, it is only a presumptive test and false positives are possible. Additionally, the reaction is not species specific. Positive reactions are not limited to human blood.
The limitations are it doesn't react with all small sugars. The test does not allow for you to determine which sample sugar is present. The test is qualitative which allow you to only detect the presence of a certain molecule.
-limitation of time -Human limitations -Systematic limitations -random limitations limitations really depend on the experiment your doing. just write things that didn't go as planned in the experiment and could have changed the outcome.
It has no limitations!

The Ames test identifies chemical mutagens.
not with ames but with animes
The substances that are test positive with Ames test may or may not be carcinogenic for humans. Similarly, some substances that cause cancer in laboratory animals do not give a positive result Ames test. It is not possible to decide the carcinogenicity of any substances only depending on the Ames test.
Ames test would typically be carried out in the field of biology, more specifically toxicology. The Ames test involves testing genetics, which involves taking a sample and examining it closely in a laboratory.
The Ames Test
The benzidine test is a test for cyanide. The limitations of this test are that benzidine has been linked to bladder and pancreatic cancer.
The Ames test is a quick method that uses bacteria to assay for cancer causing chemicals. A false positive is possible when a nitrogen based material is used.
Ames test is used to test whether a certain substance is mutagenic. Liver extract is optionally added to simulate the effect of metabolism, as some compounds, like benzo[a]pyrene, are not mutagenic themselves but their metabolic products are.
There are none.

Yeah you can, there is no age limitations.
