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.

when a reversible reaction is occurring in both directions at the same rate; the products and reactants do not change in concentration. a chemical reaction where the compound is broken into its constituent parts.

blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. as the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
