A student set up an experiment to show the effect of light color on photosynthesis in Elodea plants. She filled two test tubes with distilled water and placed a piece of Elodea in each of the tubes. She added a drop of phenol red, which turns red in a basic solution and yellow in an acidic solution. She blew in each tube before placing the volumeters on the top of the tube to add carbon di oxide.
She blew in the test tubes to add the carbon di oxide to the tube which caused the distilled water to become more acidic so the phenol red turned yellow, and when she exposes the tubes to different set of color lights. So, in the presence of light it turn the water into red color, which shows the process of photosynthesis depending on the wavelength of different color.

She added a drop of phenol red, which turns red in a basic solution and yellow in an acidic solution. She blew in each tube before placing the volumeters on the top of the tube. Why did she blow into the tube? Multiple Choice
1) to add oxygen to the tube
2) to add carbon dioxide to the tube
3) to add carbohydrates to the tube
4) to add sodium bicarbonate to the tube
Answer:
kinetic energy
Explanation:
When the molecules or atoms of a substance have high kinetic energy, the atoms/molecules move rapidly and collide frequently and harder. Most collisions are inelastic meaning that some of the energy in the collision is lost mostly as heat. This is why increasing the kinetic energy of a substance’ atoms/molecules causes the temperatures of the substance to rise. This is how heating by magnetic induction works.
