Carbohydrates and lipids are both sources of energy. The breaking of carbon and hydrogen bonds on carbohydrates and lipids release energy for use by the cells.
There is NOT a difference in speed between a car going forwards at 5 m/s and a car moving backwards at 5 m/s.
Speed is just the rate of change of the position of an object. It is calculated by dividing the change in position (distance traveled) by the time it takes to move said distance.
The distance between the two points is always positive because the direction does not matter.
However, if we are looking for the velocity, the direction DOES matter. In this example, the velocity moving forwards is 5 m/s while the velocity moving backwards is -5 m/s.
In other words:
<em>Speed </em>is looking at the <em>magnitude</em>
<em>Velocity </em>is looking at the <em>magnitude </em><em>and </em><em>direction.</em>
Mitosis - Asexual, diploid, 1, 2, during the synthesis phase.
Meiosis- sexual, haploid, 2, 4, during the synthesis phase.
They ensure they leave the system and they also ensure that people get the nutrients they need.
