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.

stratosphere: as the altitude increases, the air temperature increases. the stratosphere has a layer of ozone, called the ozone layer. this layer absorbs most of the ultraviolet radiation from sunlight. this results in the stratosphere being warmer.

the question isn't complete here so i can't right an answer '_'
