Answer: the heavy ball of a demolition machine is storing energy when it is held at an elevated position.
Which has potential energy
Explanation:
Answer:
a) overall charge will be neutral.
Explanation:
The Ph value for Pro will be neutral and neutral charge on the Ser. Molecules of atoms generally have neutral electrical charge. If the overall charge of a peptide is negative then it is considered as negative. Pro and Ser amino acids have neutral Ph values.
Taking into account the definition of dilution, moles of solute (option C) is the only thing about the solution that does NOT change.
<h3>Dilution</h3>
When it is desired to prepare a less concentrated solution from a more concentrated one, it is called dilution.
Dilution is the process of reducing the concentration of solute in solution, which is accomplished by simply adding more solvent to the solution at the same amount of solute.
In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volume (and weight) of the solution increases.
A dilution is mathematically expressed as:
Ci×Vi = Cf×Vf
where
- Ci: initial concentration
- Vi: initial volume
- Cf: final concentration
- Vf: final volume
<h3>Summary</h3>
In summary, moles of solute (option C) is the only thing about the solution that does NOT change.

Control is something that remains the same or constant through an experiment. And an experiment group is the group you test the one change on. (Also called the dependent variable)
