The statement which describes the potential and the kinetic energy of the water is this: THE POTENTIAL ENERGY INCREASES AND THE AVERAGE KINETIC ENERGY REMAINS THE SAME.
At boiling point of water, the heat that is been added to the water is used to break the chemical bonds that holds the molecules of the water together so that they can turn into vapour. At this point, the average kinetic energy of the water remains the same while the potential energy increases.
Answer:
Bind to the protein complex troponin.
Explanation:
Excitation of skeletal muscle caused by the calcium ions. During excitation of skeletal muscle, after calcium ions released into the cytosol, they bind to the protein complex known as troponin and causing substitutions in the protein complex.
These alterations permit protein to push out from the myosin-binding sites on the actin filament.
Answer:
I. dissolving more solute in an unsaturated solution
Explanation:
A saturated solution is the solution which contains maximum concentration of solute dissolved in solvent.
However, if the solution is being provided with energy (heating) , it will dissolve more heat and the solution that cannot even dissolve more solute after heating is super saturated solution.
<u>Both saturated and supersaturated solutions have maximum of their capacity to dissolve the solute and hence further energy requires energy and these processes are non-spontaneous.</u>
<u>An unsaturated solution can dissolve more solute easily and thus is a spontaneous process.</u>

Answer:
The correct statement is:
E - The entropy of the products is greater than the entropy of the reactants.
Explanation:
C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O
As glucose is a large molecule and then it is transformed into many molecules of water and carbon dioxide, the entropy of the system increases. If the number of molecules increases, the disorder increases.
Initial state: 7 molecules (1 glucose + 6 oxygen)
Final state: 12 molecules (6 carbon dioxide + 6 water)
