Answer: The surface water is usually saturated with oxygen, absorbed from the atmosphere and from photosynthesis of algae. In the deep water the oxygen is consumed when breaking down the organic matter that sinks from the surface. ... In areas with poor water turnover the oxygen in the deep water can become completely used up.

Answer:
potential energy!
When slowing an object down the kinetic energy is converted into potential energy. This means the car is either not in motion or slowly getting to a stopping point.
Remember! Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force!
Answer:
Cardiac output = 20 L/min
Explanation:
The cardiac output of a person refers to the volume of blood the heart pumps in a minute. The normal range for cardiac output is about 4 to 8 L/min. However, this can vary depending on the metabolic needs of the individual at any instant of time, for example, it is higher when exercising than when resting.
Cardiac output is calculated from the product of the stroke volume in liters/min and the heart rate in beats/min
Cardiac output = stroke volume * heart rate
For the individual who is running; stroke volume = 100 mL/beat or 0.1 L/beat
heart rate = 200 beats/min
Cardiac output =0.1 L/beat * 200 beats/min
Cardiac output = 20 L/min
