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>

giant stars die in supernovas and
their cores collapse, with the
protons and electrons essentially
melting into each other to form

Among the most frequently used species identification methods are: The evolutionary relationships between the unknown sequence and a set of known standard sequences are estimated using phylogenetic trees.
<h3>What is a phylogenetic tree?</h3>
Among the most commonly used species identification methods are: The evolutionary relationships between the unknown sequence and a set of known reference sequences are estimated using phylogenetic trees.
A phylogenetic tree is a diagram that depicts the evolutionary relationships between organisms or groups of organisms.
Scientists consider phylogenetic trees to be evolutionary hypotheses because the proposed relationships cannot be confirmed in the past.
Thus, every individual of same species are related to each other, so scientists can analyze another specimen from the same species.

Oxygen, it takes in Carbon Dioxide and releases Oxygen as a waste :)
