DNA
The positive test control organism for citrate utilization test is Klebsiella pneumoniae
Albumin and pepsin are both proteins, the test for proteins was positive.
This experiment tells us that a few amino acids could be created in a sterile environment of glass test tubes over a few weeks, demonstrating that it is possible for complex organic molecules to form spontaneously under abiotic conditions.
A positive test, when using Biuret reagent, would be purple-ish
polysaccharides and simple sugar

Why is it difficult to test the presence of chloride in organic compounds than in inorganic ones like hydrochloric acid?
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.
A test for the presence of oxygen for organic compounds which contain the element carbon.
because chlorine is not organic compound it is an in organic compound and organic compound dissolves only in organic compound so therefore it is too difficult
Hydroxycut cannot give you a false positive on a drug test, the same goes for pregnancy tests. Each test tests for particular drugs or compounds that would indicate whether the person taking the test has taken any illegal substances or is in fact pregnant.
Sorry, the question in incomplete there are no suggested test substances. However; polar covalent compounds are very soluble in water.
unsaturated hydrocarbons and their derivatives
Al foods contain several types of organic molecules except for foods that are essentially chemicals. These would include sugar (glucose, maltose, dextrose etc) and pure ethyl alcohol. Even these would contain trace amounts of other organic molecules as contaminants.
Yes, there are substances that can cause a false positive on a field drug test. Some common substances include over-the-counter medications, certain foods, and other legal substances. These false positives occur because the field tests are not always specific for identifying particular drugs and may react to similar compounds. A confirmatory test in a lab is usually needed to accurately determine the presence of drugs.
all carbohydrates show positive result to Molisch test. this is because Molisch test is used to distinguish carbohydrates from other organic compound.
Positive Bromine tests are for unsaturated compounds that have double or triple bonds. Decane has a single bond, so the test will be negative.
