The ball has the most potential energy at point 3?
The ball has the most potential energy at the highest point of its trajectory
When waves travel from one point to another what is transferred through the medium?
When waves travel from one point to another energy is transferred through the medium. Waves are periodic vibrations or oscillations in a medium that propagate through the medium carrying energy in the form of the movement. Exceptions to this are light and gravity waves, which do not require a medium for propagation.
How does does the Doppler effect relate to a passing siren?
Sound is a wave; the sound wave is distorted by the Doppler effect. You can clearly hear the change in pitch, from the point where the car approaches you, to the point where it moves away from you.
Is it possible for a system to have negative potential energy?
Yes. Potential energy can't be specified in absolute terms; you have to arbitrarily define a reference point. For the case of gravitation, any object below the reference point would have negative potential energy. What matters is not the number assigned to the potential energy, but the difference - this difference would be the same, even if you change your reference level.
Why can potential energy exist?
Because fields emanate from a point source. Anywhere not at that point has potential energy.

How is it possible for a point mutation to have no effect on the function of gene?
If the point mutation does not change the protein to be translated in the 3-letter sequence, then it will have no effect on the gene's function.
What is a sub-threshold change in membrane potential within the cell body that decays as it travels away from its point of origin?
synaptic/graded potential
Freezing point is the point at which a liquid turns into a solid What effect can change the freezing point?
Atmospheric pressure and the presence and concentrations of solutes affect the freezing point.

What is a potentiometric titration?
A potentiometric titration is one in which the end-point is detected by measuring the change in potential of a suitable electrode during the titration.
Why can potential energy exist?
Because fields emanate from a point source. Anywhere not at that point has potential energy.
What is a disturbance or vibration propagated from point to point in a medium or in space?
A wave
What type of energy is given off with the heat energy?

What cause the membrane potential of a neuron?
Opening or closing of ion channels at one point in the membrane produces a local change in the membrane potential, which causes electric current to flow rapidly to other points in the membrane.
