Answer:
The correct answer is C and Engelmann conducted this experiment to prove relationship between algae and the rate of photosynthesis.
Explanation: First we must talk about 3 facts:
1) Prism scatters the white light into different wavelengths.
2) Photosynthesis, 6 carbon dioxide and 6 water molecules are consumed and 6 oxygen and 1 sugar molecule is synthesized using light energy.
6CO2 + 6H2O → C6H12O6 + 6O2
3) Aerobic bacteria breaks down sugar while using oxygen and produces water and carbon dioxide in simplified terms.
So with this experimental setup a researcher can understand the rate of the photosynthesis by increased accumulation of aerobic bacteria near algae in certain wavelengths since they uses oxygen and tend to move close to the oxygen source (<u>see figure</u>). In this experiment there are no ways to measure heat (B), there is no known relation between wavelength of light and aerobic respiration since it can happen even in the dark (A) and finally there are no ways to measure carbon dioxide (D).
Answer:
1) By 11:30pm
2) Shortly before midnight (few minutes to 12:00am)
Explanation:
Since the strain of bacteria takes 1 minute to divide (double its population), and by midnight (12:00am) the entire bottle becomes full, then:
I) Subtract Initial division time from Final division time i.e 12:00 - 11:00 = 1 hour
II) Split 1 hour into two (60minutes makes 1 hour)
I hour/2 = 30 minutes
Definitely, the bottle will be half filled by 11:30pm
2) Once half filled, the rapidly dividing cells reach for the top of the bottle as midnight approaches. By 11:50pm upwards, bottle space must have been running out
Answer:
Reflected Light
Rays of light reflect, or bounce off objects around us.
Mycology is the study of fungi.
