Griffith's experiment worked with two types of pneumococcal bacteria (a rough type and a smooth type) and identified that a "transforming principle" could transform them from one type to another.
At first, bacteriologists suspected the transforming factor was a protein. The "transforming principle" could be precipitated with alcohol, which showed that it was not a carbohydrate. But Avery and McCarty observed that proteases (enzymes that degrade proteins) did not destroy the transforming principle. Neither did lipases (enzymes that digest lipids). Later they found that the transforming substance was made of nucleic acids but ribonuclease (which digests RNA) did not inactivate the substance. By this method, they were able to obtain small amounts of highly purified transforming principle, which they could then analyze through other tests to determine its identity, which corresponded to DNA.
Mountain slopes have faster erosion because it is easier for fast moving bodies of water to carry down eroded material downhill, rather than across flat land.
Answer:
Photosynthesis stores energy, and respiration releases energy.
Explanation:
When plants doing photosynthesis, they will catch the energy from sunlight. The reaction then will store the energy by making glucose. Glucose has high energy that can be released by doing respiration.
Respiration will break down glucose using oxygen and the energy stored inside glucose is released. The energy will be used to synthesize ATP and ATP will be used as main energy.
