Answer:
Because oxygen is the combustion fuel and glucose is the substrate needed for synthesis of energy as ATPs during cellular respiration.Therefore Guillermo lacks enough energy as ATPs in her body cells, especially skeletal muscles cells to complete the task of ascending the s steps.
For all the mitochondrial in cells(sites of energy production) to receive needed glucose,and other metabolites needed for energy synthesis; an efficient transport system is needed, so that these materials are available immediately, in required amount. This system is called circulatory system.
And for the the supply of combustion fuel (oxygen) needed for the completion of the ATP synthesis mechanisms; respiratory systems which convey oxygen from the external environments to the circulatory system through breathing mechanisms, for distribution is needed.
Thus the doctor needs to test both the circulatory and respiratory systems.
Explanation:
The equilibrium constant k is actually the ratio of the
concentration of the products over the concentration of reactants at equilibrium. So if the
concentration of products < concentration of reactants, therefore the
constant k will be small. But if the concentration of products >
concentration of reactants, the constant k will be large. In this case the
value is too small (x10^-19), therefore we can say that the reaction favors the
reactant side:
the equilibrium lies far to the left
Answer:
For example, when we bake a cake, it's a result of a mixture of eggs, flour, sugar, and other ingredients. Any time two or more items are combined, a mixture is formed. Sometimes, the different parts of a mixture can be separated into individual entities. Other times, they're married for as long as they exist.

Answer:
Wave theory of light that states that visible light irrespective of its color, can cause the ejection of electrons when it strikes a metal.
Explanation:
Wave theory of light:
- If we go through wave theory of light, it clearly focuses that light is of actually wave nature not particle nature.
- The wave theory was based on the ideas of Hertz who discovered in 1887 that metallic surface can emit heat energy (electrons) when light hits the metal. If we increase the intensity of light, it will also increase the incident energy and ultimately increase the kinetic energy of electrons.
- Moreover, the frequency of light do not matters much, just a beam of light can eject the electrons from the metal.
Photoelectric effect:
On the other hand, Photoelectric effect can be considered only if we assume that light has particle like nature and not wave like nature.
- It also says that frequency of light matters alot in ejecting the electrons from the metals. If the frequency of light is less, it will not eject electrons from the metal surface even if it falls on metal for a very long time.
- It also says that maximum kinetic energy of the electrons (that are emitted) corresponds with the light frequency that caused the emission of electrons.
- The current of emitted electrons is directly proportional to the intensity of light that caused the electron emission.
We can see that the postulates of wave theory (like no.3) are just opposite to the postulates of photoelectric effect. The photoelectric effect also explained the relationship between emitted electrons and light in a better way that was not described by wave theory. We can say that it is as advanced explanation of facts based on the classical theory of wave like nature of visible light.
