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.
Temperature is independent and the amount of salt dissolving in water is dependant. This is because the amount of salt dissolving depends on how low or high the water temperature is
Answer:
426 mg = 4.26 x 10² mg
Explanation:
1 cup = 237.6 mL x 1 L/1000 mL = 0.2376 L
We divide the liters of milk the student drinks into the volume in liters of a cup to calculate the number of cups the student drinks per day:
number of cups per day = 0.318 L/0.2376 L = 1.34 cup
Now, we multiply the number of cups by the amount of calcium that a cup of milk has:
amount of calcium = 1.34 cup x 318 mg = 426 mg = 4.26 x 10² mg
Therefore, the student gets 426 mg (or 4.26 x 10² mg) of calcium in one day.
