Scientists are studying compounds and a newly discovered rain forest plant. the plant produces in unusual substance that local people from the area say acts as an anesthetic. one scientist tested the substance with the chemical indicator soudan 3. if the test is negative, which type of macro molecule is not present in the substancea.) protein b.) lipidc.) nucleic acidd.) carbohydratescientists are studying compounds and a newly discovered rain forest plant. the plant produces in unusual substance that local people from the area say acts as an anesthetic. if another scientists test the substance using iodine, which macro molecule is the scientists testing for? ( same answer choices as before) .

Option B , Lipid

Explanation:

Sudan III is a dye which is used for testing the presence of non-polar substances.

All fat compounds such as -

oils

waxes

greases

fat emulsions

& other hydrocarbon products

can be  tested through Sudan III .

Thus, any substance which is tested for SUDAN III shows negative result , then it simply means that the substance lack fat macro molecules and hydrocarbons

Thus , option B is correct.

the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.
