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.
How do you get the same amount of oxygen to dissolve in plasma as carbon dioxide you would have to?
To get the same amount of oxygen to dissolve in plasma as carbon dioxide, you would need to increase the partial pressure of oxygen in the gas phase. This increase in pressure would drive more oxygen molecules to dissolve into the plasma to reach equilibrium with the gas phase. The solubility of a gas in a liquid is determined by Henry's Law, which states that the amount of gas dissolved is directly proportional to its partial pressure in the gas phase.
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
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.

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.
From your graph of the temperature data what is the effect of temperature on the amount of oxygen that water at different temperatures can hold?
Temperature has an effect on the amount of oxygen that water can hold. The resulting graph would be almost parabolic in nature as the amount of oxygen will increase at both a high and low temperature as seen with balloon expansion when filled with steam and also a soda can bulging when frozen.
Which region would you expect to find the largest amounts of dissolved oxygen in the ocean water?
You would expect to find the largest amounts of dissolved oxygen in the surface layer of the ocean, particularly in regions with high levels of phytoplankton and strong wave action which help to oxygenate the surface waters.
Why does the amount of Magnesium Oxide not increase when the amount of magnesium is increased?
When magnesium reacts with oxygen to form magnesium oxide, the ratio of magnesium to oxygen is fixed according to the chemical equation (2Mg + O2 -> 2MgO). This means that the amount of magnesium oxide that can be formed is limited by the amount of oxygen available, not by the amount of magnesium present. So, increasing the amount of magnesium does not lead to a corresponding increase in magnesium oxide produced.
Which change in a sample of pond water could indicate that heterotropic microbes were active?
An increase in the levels of organic matter or a decrease in dissolved oxygen in the pond water could indicate that heterotropic microbes are active. This is because heterotrophic microbes decompose organic matter for energy, which can lead to changes in the water quality parameters.
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 change would increase the amount of gas able to be dissolved in a given amount of liquid water?
Reducing the temperature and increasing the pressure would increase the solubility of gas in liquid water. This change would allow more gas molecules to dissolve in the water by creating conditions that favor gas dissolution.
