One reason may be because of they were being bullied so they want people to know how they felt like?
Solar panels, windmills, hydro energy
Answer:
industrial wastes dumped into rivers
Explanation:
Because when factory and other industries dumped their wastes into water they begin to react on environment and fishes will die and that water or river smell so bad
Limestone: Flaky and mainly made of bones.
Shale: Fine grained and made of clay fragments.
Flint: Hard rock made up of mineral quartz. Also can be used to make fire (flint and steel)

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).
