The event was volcanic eruption.

The second largest volcanic eruption took place in June 1991. The volcanic eruption took place in the Mount Pinatubo (a chain of volcanoes along the Luzon arc) on the island of Luzon in the Philippines. After the millions of tons of sulfur dioxide were discharged into the atmosphere, resulting in a decrease in the temperature worldwide over the next few year.

Theodor W. Engelmann illuminated a filament of algae with light that passed through a prism, thus exposing different segments of
WARRIOR [948]

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).

Rudik [331]

Answer: Rheumatoid arthritis

Explanation:

Rheumatoid arthritis is a disease which is a autoimmune disease which is usually associated with the pain and inflammation in the joints. This is the condition in which the person is not able to walk or sit for a longer period of time as it is painful.

The lysosomes is an enzyme that is found in the saliva and tears of human beings which helps in the degradation of the cell wall.
