Answer:
- contains oxygen
- provides warmth
- blocks harmful energy from the Sun
Explanation:
The atmosphere is crucial when it comes to providing living conditions on Earth. The gases in the atmosphere manage to balance the things just about right, so that the life can thrive. The atmosphere has oxygen, the gas that is used by pretty much every organism to be able to function. With its greenhouse gases, the atmosphere manages to trap the heat inside, thus providing warmth to the Earth. The numerous layers of the atmosphere manage to block in big portion the harmful energy from the Sun, with a special accent on the ozone layer, a layer that manages to stop most of the UV radiation.
Explanation:
Carbon exists in several isotopes. ... Carbon has the atomic number of 6 which means that all isotopes have the same proton number. However, the number of neutrons is different, thus giving different mass numbers. Carbon-12 has 6 neutrons, carbon-13 has 7 neutrons, and carbon-14 contains 8 neutrons.

I didn't know anything about this topic but I looked it up. For the other words I would look up the other words and see what they have to do with plants withering.
Answer:
a. 0.191 ppm b. 4.962 ppm c. 0.0385 ppm
Explanation:
a. 17 g of calcium = 0.017 mg. 89 mL = 0.089 L.
So our concentration = 0.017 mg/0.089 L = 0.191 mg/L = 0.191 ppm
b. 0.65 mg of caffeine in 131 mL = 0.131 L.
So our concentration = 0.65 mg/0.131 L = 4.962 mg/L = 4.962 ppm
c. 0.35 mg of trace particle in 91 dL = 9.1 L.
So our concentration = 0.35 mg/9.1 L = 0.0385 mg/L = 0.0385 ppm
