Great question!
<span> mechanical
advantage is the factor of which a machine multiplies the force put
into it. For example, if a simple machine has a mechanical advantage of 3
it means that it made the work you did 3 times easier or you only had
to put in 1/3 the force you would have if you didn’t have the simple
machine.
</span>
To calculate the mechanical advantage of a wheel and axle you must divide the radius of the wheel by the radius of the axle.<span>Therefore
larger wheels means that the speed of the wheels is faster than the
speed of the axle and for each rotation the axle makes the wheels are
making multiple rotations. A mechanical advantage of 5 means that the
wheels are moving 5 times faster than the axle.
</span>
<span>F = MA= radius of wheel/radius of axle</span>, this is 1 when the radius of both the wheel and axle are the same,and greater than one when the radius of the axle is less than the radius of the wheel.

Explanation:
Answer:
Plants are a source of food, fuel and medicine.
Explanation:
In biology, plants are photosynthetic living beings without locomotive capacity whose cell walls are mainly composed of cellulose.
The importance of plants for humans is indisputable. Without them we could not live, since the plants participated in the composition of the gases present in the Earth's atmosphere and in the ecosystems, and are the primary source of food for heterotrophic organisms. In addition, plants have direct importance to man: as a source of food; as building materials, firewood, fuel and paper; as ornamental; as substances that worsen or improve health and therefore have medical importance; and as a consequence of the latter, as the raw material of the pharmaceutical industry.
