A plant cuticle is a protecting film covering the epiderms of leaves, young shoots and other other aerial plant organs with out periderm. It consists of lipid and hydrocarbon polymers impregnated with was and is synthesized exclusively by the epidermal cells.

Question:
<em>The diagram shows the potential energy changes for a reaction pathway.</em>
Part 1: Does the diagram illustrate an endothermic or an exothermic reaction? Give reasons in support of your answer.
Part 2: Describe how you can determine the total change in enthalpy and activation energy from the diagram and if each is positive or negative.
Answer: 
Part 1: The diagram illustrates an endothermic  reaction as the products has a higher potential energy than the reactants do. There is a positive slope of the diagram and there is enough energy to meet the activation energy requirement. 
Part 2: You can determine the total change in enthalpy and activation energy from the diagram by the potential energy of the reactants. If the reactants have a high potential energy, then the enthalpy is also high, and if the reactants have a low potential energy, then the enthalpy is low. You can determine if the diagram is positive or negative by knowing if its an endothermic or exothermic reaction. An endothermic reaction is positive because the products are higher than the reactants and a exothermic reaction is negative because the reactants are higher than the products.
 
        
             
        
        
        
Neptune's gravitational factor relative to earth is 1.19.
That means we have to multiply 8.5 by 1.19.
8.5 * 1.19

Answer; 
B. Jumping rope
Explanation; 
Jumping rope is not an anaerobic exercise but an aerobic exercise. 
Anaerobic exercise is a form of high intensity exercise that increase the oxygen debt. However since the muscles require oxygen to maintain prolonged exertion, anaerobic exercises can only last for short periods of time.
Examples of anaerobic activity sprinting, high-intensity interval training, power lifting and most athletic sports.
