Explanation:
Newton's second law states the "net force on a body is the product of its mass and acceleration".
When a body has a net force acting on it, it will change position and begin to move.
Ordinarily, a car will not move until it is towed when the engine is faulty. The weight of the car and the frictional force of the tire acts to prevent its motion.
Now, the towing van supplies a force that is greater than the weight of the car and the frictional force between the tires. This way the towing van is able to move the faulty car.

D. Cell membrane: surrounds a cell and allows substances to pass in and out
When a substance changes into a different substance, you are observing its chemical properties.
In a physical change, the substance must <em>not </em>change into a different substance.
The physical and chemical properties of a substance do <em>not</em> change.
Answer:
It is mostly water (up to 95% by volume), and contains dissolved proteins (6–8%) (e.g. serum albumins, globulins, and fibrinogen), glucose, clotting factors, electrolytes (Na+, Ca2+, Mg2+, HCO3−, Cl−, etc.), hormones, carbon dioxide (plasma being the main medium for excretory product transportation) and oxygen.
hope this helps :)
