Answer:
Dissolved Oxygen and Water. Although water molecules contain an oxygen atom, this oxygen is not what is needed by aquatic organisms living in natural waters. A small amount of oxygen, up to about ten molecules of oxygen per million of water, is actually dissolved in water. Oxygen enters a stream mainly from the atmosphere .
Explanation:
I want to investigate how temperature affect the concentration of oxygen in air as it will affect how much oxygen we inhale per breathe. Oxygen by percent composition in air is 20.95%. However, the oxygen concentration/density in air varies due to the expansion of gas particles and varies inversely wth temperature according to P/RT=n/V.

Answer:
Due to gravity and volatile matter.
Explanation:
- As the rocky matter is refractory as it forms in the relatively high and warm and the presence of the gravity also plays a crucial role in the formation of the rocky masses.
- The volatile matter solidifies at a cold temperature and such as those in the outer parts of the nebula and thus gas giant is cold and icy plants as they form away from the sun and have distinct gravitational compositions.

Answer:
3:08 pm
Explanation:
the degree. between the two towns is 47 .
47*4/60= 188/60 =3 2/5 hours.
time in the east is ahead than time in the West ,so we add 3 2/15 hours to the time in Buchanan.
thus we get 1508hours
