Think of one or two products sold in this country that are tested using the scientific method before they are placed on the market and then later found to be dangerous explain how faulty or incomplete testing of a product can become a threat to health and give two specific

Explanation:

Well, I can only think of one example and that would be certain medications. Usually medications are tested in mice (it diverted a few years earlier, but still share over 90% of genetic similarity). You have to follow the scientific method to test the effectiveness of such to treat and/or prevent certain disorders. Faulty or incomplete testing is highly unlikely, for the scietific community today is very thorough during the experimentation process; however, there has been certain medications that have resulted in severe secondary or side effects. For example steroids.. Steroids are helpful in the treatment of allergic reactions or other autoimmune diseases; however, it has been shown (in horses as well as in humans) that it reduces fertility by lowering testosterone concentrations in the blood plasma and it slows down its production. Low testosterone results in decreased counts of sperm and abnormal morphology of the cells. Other problems include liver problems and hypercholesterolemia.

Hope this helps

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
