B. sodium and chloride because an ionic bond only form between oppositely charged particles.
Distance travelled by Bob was 7 meters and the displacement was 5meters.
<h3><u>Explanation:</u></h3>
Distance is defined as the total length of the path travelled by a body from its initial position to final position. Displacement on the other hand is defined as the length of the straight line joining the initial position and the final position of the body.
Here, Bob travelled from point A to point C via point B which took him to travel more distance. The length of distance from point A to B is 4 meters and from point B to C is 3 meters. So the total distance covered is
meters = 7 meters.
While the length of path straight from point A to C is 5 meters. So displacement is 5 meters.
The answer is NAD+.
NAD+ is the primary oxidizing agent in the glycolytic pathway. Oxidizing agents gain electrons and thus, they are reduced in a reaction. In the glycolytic pathway, NAD+ server the oxidizing agent. It accepts electrons from the molecules, such as some intermediates of the glycolytic pathway. As the result, it is reduced to NADH which can serve in some reactions as a reducing agent.
