Radioisotopes are frequently used to label molecules in a cell. The fate of atoms and molecules in a cell can then be followed. Assume Saccharomyces cerevisiae is grown in a nutrient medium containing the radioisotope 35S. After a 48-hour incubation, the 35S would most likely be found in the S. cerevisiae's.

Proteins

Explanation: Saccharomyces cerevisae cells produce proteins from Ribonucleic acid (RNA) after incubation in a suitable growth medium. The proteins synthesized are necessary for their optimal growth.

we would need to see the picture to answer it

chert is a sedimentary rock composed of microcrystalline or cryptocrystalline silica. with this little bit of information, you can come to the conclusion that your answer is c.  

explanation:
