Answer:
- Mechanical advantages allows humans to perform tasks much easier in terms of the force they need to apply, but must always obey the conservation of energy.
- Mechanical advantage is a measure of the ratio of output force to input force in a system, used to analyze the forces in simple machines like levers and pulleys.
- A good example is pushing a heavy object up a ramp. It may be easier to push the object up a ramp instead of just lifting it up to the right height, but it takes a longer distance.

Calculate the concentration of the solution after the dilution.
C1 * V1 = C2 * V2
The initial solution:
C1 = 250 mL
V1 = 0.96 M
The final solution:
C2 = ?
V2 = 800 mL
250 mL * 0.96 M = C2 * 800 mL
C2 = 250 mL * 0.96 M / 800 mL
C2 = 0.30 M
Answer:
Opposite.
Water exhibits negative charge near hydrogen, positive near oxygen.
This is why it is OPPOSITE.

The circulatory system is composed of blood, vessels and the organs like the heart. The immune system and the excretory system will be affected.
<h3>What are the immune system and the excretory system?</h3>
The immune system is the protective system that provides immunity to the body by fighting pathogens. The cells of the circulatory system like white blood cells play a major role in fighting pathogens.
The excretory system includes the kidney that majorly functions in the purification of the blood and will get affected by the circulatory system. No filtration and circulation of the blood and its components will occur.
Therefore, immune and excretory systems will be affected by the circulatory system.
