What causes radon in caves and how do you know if you are being exposed to dangerous levels?

1. A cave is non ventilated volume and the concentration of radon is greater than outdoor. 2. Determination of radon concentration (in Bq/m3 or in pCi/L). The maximum concentration should be under 150-250 Bq/m3.


What is going to happen to the pH when elodea is exposed to light?

The pH of the water will increase when elodea is exposed to light. This is because during photosynthesis, elodea will take in carbon dioxide, which will result in a decrease in carbonic acid concentration, leading to an increase in pH.


What is a natural occurring stimulus that leads to an involuntary response?

stimulus discrimination


What is minimum concentration of alcohol in water that is flammable?

The minimum concentration of alcohol in water that is flammable typically starts around 50% alcohol by volume (ABV) for ethanol. At this concentration, the mixture can produce enough vapor to ignite when exposed to an open flame or spark. However, lower concentrations can also be flammable under certain conditions, particularly if the mixture is heated or if the vapor concentration is high enough. Always exercise caution when working with flammable substances.


What will be the color of leaves of a plant not exposed to sunlight?

The leaves of a plant not exposed to sunlight will likely be pale or yellowish in color due to the lack of chlorophyll production. Chlorophyll is responsible for the green color of leaves and is essential for photosynthesis, which requires sunlight to occur.

Why doesn't cytolysis happen in elodea?

Cytolysis does not happen in the elodea because of the concentration of its cells. The concentration that surrounds the cells are usually less concentrated and therefore prevent cytolysis from occurring.
