Explain why you agree or disagree with each of the following statements: a. We should not worry much about exposure to toxic chemicals because almost any chemical, at a large enough dosage, can

A student analyzed arsenic content on a fish sampled from contaminated coastal area. In this study, fish sample recorded 70.8 g/kg of arsenic content. Suggest a suitable analytical instrument to be used in this analysis and draw a conclusion on the safety of arsenic content of this fish sample

Name the three basic classes of drug targets in medicinal chemistry and indicate, which are the most/least important as targets for biologics? I don't sure if I answer these questions correctly. Hope someone can give me confirmation and explain to me how enzymes will be affected by bioloigcs?   My answer so far: The three common classes of drug targets are; receptors, nucleic acid, and enzymes. As a target for biologics, the least important will be a nucleic acid, and the most important will be receptor and second enzymes. Biologic drugs such as monoclonal antibodies will bind to the antigens, which are overexpressed receptor that need to be deactivated. In this case, the monoclonal antibodies will act as an antagonist and block the ligand from binding to the antigens, which are extensively presented in cancer cells. In addition, it can also affect enzymes by.......?

Radioactive decay produces ionising radiation.  Like all ionising radiation this can lead to harmful effects on living tissue due to cell damage including damage to DNA, mutation and cell death.  Contrast the differing health risks associated when working with alpha, beta or gamma radiation sources.
