Answer:
A and B only.
Explanation:
DNA is present as the genetic material of the living organism. Hershey and Chase experiments confirmed that only DNA is transmitted from one generation to the next generation.
They used radioactive phosphorus and sulfur and infects the cells with bacteriophage. The radioactivity labelled with phosphorus is present in the next generation whereas the radioactive sulfur molecules are not present in the next generation. DNA contains phosphorus whereas sulfur is present in the proteins.
Thus, the correct answer is option (D).
Answer:
Force of gravity!
Explanation:
The reason I say this is because a "dependant varible" is a variable that is being measured in a science experiment. Even though potential energy could be the answer it isn't because in this experiment the kinetic and potential energy are being measured. Depending on the height of the ball on the ramp the force of gravity will depict whether it goes faster and longer.
