Answer:

C.

The amount of folic acid is the independent variable, and the DNA synthesized is the dependent variable.

Explanation:

Since the aim of the study is to know the effect of folic acid on the process of DNA synthesis, the experimental system should be given a different amount of folic acid. Respective change in DNA synthesis would represent the effect of the amount of folic acid on the process. Therefore, the amount of folic acid is the independent variable which would affect the dependent variable, that is, the DNA synthesized.

Alexandra fleming was working with a bacteria called staphylococcus which looked like bunches of grapes under the microscope. He
denis-greek [22]

Answer:

In 1928, Sir Alexander Fleming was studying Staphylococcus bacteria growing in culture dishes. He noticed that a mold called Penicillium was also growing in some of the dishes. A clear area existed around the mold because all the bacteria that had grown in this area had died. In the culture dishes without the mold, no clear areas were present.

Fleming thought that the mold must be producing a chemical that killed the bacteria. He decided to isolate this substance and test it to see if it would kill bacteria. Fleming transferred the mold to a nutrient broth solution. This solution contained all the materials the mold needed to grow. After the mold grew, he removed it from the nutrient broth. Fleming then added the nutrient broth in which the mold had grown to a culture of bacteria. He observed that the bacteria died. He also added the same type of broth that had not been exposed to the mold, to a culture of the same type of bacteria. Nothing happened to the bacteria.
