morpeh [17]

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.

Boyle’s law gives the relationship between pressure and volume of gases. It states that at constant temperature the pressure of gas is inversely proportional to volume of gas.
PV = k
Where P is pressure V is volume and k is constant
P1V1 = P2V2
Parameters at STP are on the left side and parameters for the second instance are on the right side of the equation
P1 - standard pressure - 1.0 atm
Substituting the values in the equation
1.0 atm x 5.00 L = P x 15.0 L
P = 0.33 atm
New pressure is 0.33 atm

Describe an element and a compound. Compare and contrast their similarities and differences. Identify how elements are related t

Alenkasestr [34]

Answer:

» Similarities :

☑ They both react by chemical means, to produce either an element or compound as the end product of the chemical reaction.

• Take an example of Magnesium reacting with cold water:

${ \rm{Mg_{(s)} + 2H _{2} O _{(l)} → Mg(OH)_{2(aq)} + H_{2(g)}}}$

• If it reacts with steam:

${ \rm{Mg _{(s)} + H _{2} O_{(l)} → MgO_{(s)} + H_{2(g)}}}$

• [ Element: Magnesium and Compound: Water ]

They are both classified under atomic substances cause they are made up of microscopic molecules known as atoms.

☑ They are both formed up by microscopic substances known as atoms.

» Differences :

☑ Compounds generally have higher molecular masses than elements.

☑ Compounds are formed through bonding by elements while elements can naturally exist or formed by extraction, purification and concentration
