When exercising carbohydrates an fats are oxidized to release energy used by muscles, during this oxidation 1 liter of oxygen is equivalent to approximately 5 calories. Therefore if one liter of oxygen is consumed every minute during exercise, then in an hour 60 liters of oxygen will have been used. But since one liter of oxygen is equivalent to 5 calories, then in an hour 300 calories will have burned.
Considering the definition of volume, the volume of a cube with a side length of 3 centimeters is 3 cm³.
<h3>Volume</h3>
Volume is a measure of the space occupied by an object in three-dimensional space.
In other words, volume of a geometric figure is defined as the amount of space occupied by the object or figure in three-dimensional space. Volume is measured in cubic units.
The volume of a cube is equal to the measure of its side to the cube. That is to say:
Volume = side x side x side = side³
<h3>This case</h3>
In this case, you have a cube with a side length of 3 centimeters. Replacing in the definition of volume:
Volume= 3 centimeters× 3 centimeters× 3 centimeters
Solving:
<u><em>Volume= 3 cm³</em></u>
Finally, the volume of a cube with a side length of 3 centimeters is 3 cm³.

Answer: After 3 rounds, 8 segments having 2 original strands on different segments will be present.
Explanation:
The polymerase chain reaction selectively and repeatedly copy the double stranded DNA (dsDNA) in the PCR machine.
1st round:
Single piece of double stranded DNA (dsDNA) unwinds in two seperate strands, before complementary nucleotides are synthesized to establish double helix.
2nd round:
The two dsDNA yields 4 segments before complementary nucleotides are synthesized
3rd round:
The four dsDNA yields 8 segments before complementary nucleotides are synthesized.
Therefore, at the end of 3 rounds, the two original strands will be present on the 8 different segments of copied DNA.
