Elisa is traveling from Winston Salem to Las Angeles to visit Yetzeli who is 2,439 miles away. By plane it takes her 6 hours. Using the same route back it takes 8.5 hours. Calculate the speed of both routes and why the difference in the return trip.
The speed of both routes is 654.2 km/s and 461.78 km/s respectively.
Calculation:-
1 mile = 1.61 km
2,439 mile = 2,439×1.61 km
= 3925.19 km
Speed of the First route,
Given time = 6 hours
displacement = 3925.19 km
Speed = 3925.19 km/ 6
= 654.2 km/s
Speed of the second route,
Given time = 8.5 hours
Distance = 3925.19 km
Speed = 3925.19 km / 8.5 hours
= 461.78 km/s
The difference in the return trip is due to the difference in speed.

All cells require energy to function, but muscle cells typically have significant energy needs that can only be satisfied by the mitochondria, the cell's powerhouse. Muscles have many mitochondria, allowing them to respond rapidly to the body's energy needs. They transform glucose into ATP, a chemical with a vast energy storage capacity.
If glucose is the sole energy source for cellular respiration in an animal, what proportion of the carbon dioxide exhaled is derived from oxidation of pyruvate to acetyl coa?.
The oxidation of pyruvate to acetyl CoA yields 1/3 carbon dioxide on glycolysis.
Glycolysis occurs in the cytoplasm and results in pyruvate. Pyruvate oxidation takes place in the mitochondrial matrix.
The following reaction results in the conversion of pyruvate to acetyl-CoA:
Pyruvate + NAD⁺ + CoA-SH ⇒ acetyl-CoA + NADH + CO₂
One molecule of pyruvate is converted into one molecule of carbon dioxide.
Also, two molecules of pyruvate are converted into two molecules of carbon dioxide (as glucose on glycolysis yields 2 molecules of pyruvate).
Acetyl-CoA also contributes to the citric acid cycle and generates two molecules of CO2.
Pyruvate thus generates a total of 3 molecules of CO2, whereas glucose generates 6 molecules of CO2 (as glucose on glycolysis yields 2 molecules of pyruvate)
Therefore, we get that pyruvate produces total 3 molecules of CO₂ and glucose produces 6 molecules of CO₂ (as glucose on glycolysis yields 2 molecules of pyruvate).

- Explain why an element's charge is related to the group on the periodic table to which it belongs
Answer:
Because of the elements' number of valence electrons.
Explanation:
the number of valence electrons (number of electrons in the outermost shell) determines the number of bonds an element can make and how close they are to having a filled shell, which elements are the most stable when their outermost shell is filled (8 electrons for smaller elements). For example, in group 1, the elements have one valence electron, which in order to have a filled shell, they would have to lose one electron. That would make their charge +1. On the otherhand, in group 7, the elements have 7 valence electrons. In order to achieve a full outer shell, they would have to gain one more electron. For example, Cl will form an ionic bond with Na (group 1), which Cl will take Na's 1 valence electron, resulting in a total of 8 valence electrons, which Cl will become -1 charge (one more electron than it originally has) and Na will become a +1 charge (one less electron than it originally has).
Because the group number represents the number of valence electrons in the outermost energy level of an atom, and the charge of an element is determined by the number of valence electrons it has.
What is valence electron?Valence electrons are electrons that are found in the outermost energy level of an atom. They are responsible for the chemical properties of an element and play a crucial role in determining how the element will react with other elements.
Valence electrons are important because they are the ones that are involved in forming chemical bonds with other atoms. The number of valence electrons an element has is determined by its atomic number
Valence electrons are important because they are the ones that are involved in forming chemical bonds with other atoms.
