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:
maybe something like:
1. what caused their extinction primarily
2. why could they not survive through the situation they were in
3. how do we know what specific event occurred using only the resources we have today
Explanation:
I hope this gave you a bit of insight :))!
The answer is : D)
It attracts Us but it is not strong enough for us to feel it. That is because we are too far away. If we were closer to Mars, we would be able to feel the force of attraction.
Hope this helped.
<span>The correct answer is A. the description of human struggles in the form of Ivan Ilyich's suffering. This part is really realistic - it shows us what can actually happen in life, and what often does, and Tolstoy showed us Ivan's suffering without hiding anything or romanticizing his illness. The other options refer more to Romanticism than to Realism. </span>
