How does pollution affect the dissolved oxygen in water?
It polluties it, beacuse the nutrients we won't have and when we fish the, water would be polluted and all of the fish would be dead...!
Would an increase in contractility cause an increase to cardiac output?
Yes - an increase in contractility would lead to an increase in stroke volume. An increased stroke volume would cause an increased cardiac output.
What would happen to cardiac output if the stroke volume increased and the heart rate stayed the same?
Since the stroke volume increased then the cardiac out put would increase, pumping out more blood with the same amount of heart beats.
Would a 2 for 1 stock split cause retained earnings to increase?
No. The ONLY thing it would do to a balance sheet is increase the number of shares, and that is a footnote.
Why do scientists that study rocks and fossils suggest that oxygen wasn't in Earth's atmosphere until one celled organisms appear?
because having oxygen would have destroyed the the cells. However without oxygen there would be no ozone layer and the cells would have been fried. This is one of the many problems evolution has.
What would happen to the amount of dissolved oxygen in the river if the river is polluted?
the amount of dissolved oxygen would decrease.
What change would increase the amount of gas able to be dissolved in a given amount of liquid water?
Increasing pressure.
Can you mix oxygen with water to make acid?
No. You would just get water with some dissolved oxygen in it. This dissolved oxygen is essential for most aquatic life. Acids are a variety of substances that will increase the concentration of hydrogen ions when added to water.
What would help increase the amount of oxygen?
plant more trees
Which action would be least likely to harm endangered species?
decreasing the amount of dissolved oxygen in the oceans
How do you get the same amount of oxygen to dissolve in plasma as carbon dioxide you would have to?
Increase partial pressure of oxygen
Where would you expect to find the largest amounts of dissolved oxygen in the ocean water?
Oxygen best dissolves at surfaces. So generally, you would find the largest amount of dissolved water at the surface, which is in contact with the air. As for a region, I would assume a region that has a lot of photosynthetic organisms and not a lot of oxygen consumers. Another factor that should be kept in mind, is that the lower the concentration of solutes (i.e.. salt) in the water, the more oxygen can be dissolved. For example, at 10 degrees Celsius, up to 8.02mL of oxygen can be present per liter of freshwater, but only 6.75mL of oxygen is dissolved per liter of saltwater. ______________ In polar regions. In polar regions
Which region would you expect to find the largest amounts of dissolved oxygen in the ocean water?
In polar oceans because the solubility of oxygen increases with decreasing temperature
What would be expected if the amount of interstitial fluid surrounding the capillary beds of the lungs were to increase significantly?
the amount of oxygen entering the circulation from the lungs would decrease.
Would you expect a fast moving mountain stream or the Mississippi River to have more dissolved oxygen?
I personally would expect the mountain stream to have more dissolved oxygen, because I know that oxygen dissolves better in cold water.
What happens when fertilizer gets into pond?
It would decrease the dissolved oxygen because it would stop the plants from making oxygen.
Explain why when air pressure is low it is more difficult for the cells the body to obtain the oxygen they require?
because the level of oxygen in the air is so low, the body would need to breath more often to be able to absorb the same amount of oxygen it would at a lower altitude. So, breathing rate would increase. also the heart rate would increase.
