Explanation:
During periods of strenuous activity muscle cells run low on oxygen.
What are muscle cells?Muscle cells are defined as the cellular components of muscle tissue. Muscle cells are designed to contract, or produce a pulling force, in order to stabilize or move different body parts. Skeletal, visceral, and heart muscle cells are the three different types. They are located in the organs' hollow walls. The muscular system is made up of a variety of muscle types, each of which is essential to how the body works.
Lactic acid is produced and accumulates in the muscle when there is a high energy demand, rapid changes in the energy requirement, and a lack of oxygen. During prolonged, intense activity, muscle pH falls to 6.4–6.6. Your muscles are forced to contract as forcefully as they can during this form of exercise, which results in an increase in the number of contractile filaments in your muscle cells.
Thus, during periods of strenuous activity muscle cells run low on oxygen.

Answers
Answer:
From Hawaii’s Maunakea, astronomers around the world use W. M. Keck Observatory to observe the universe with unprecedented power and precision.
The twin Keck Observatory telescopes are the world’s most scientifically productive optical and infrared telescopes. Each telescope weighs 300 tons and operates with nanometer precision. The telescopes’ primary mirrors are 10-meters in diameter and are each composed of 36 hexagonal segments that work in concert as a single piece of reflective glass.
In the middle of the Pacific Ocean, Hawaii Island is surrounded by thousands of miles of thermally stable seas. The 13,796-foot Maunakea summit has no nearby mountain ranges to roil the upper atmosphere. Few city lights pollute Hawaiian night skies, and for most of the year, the atmosphere above Maunakea is clear, calm and dry -— offering the best seeing on Earth.

Convert 1.55 x 10^24 ATOMS OF CARBON TO MOLES OF CARBON
Answers
Answer:
2.57 moles of carbon
Explanation:
1 mole = 6.023x10^23 (this is called avogadro's number)
1/6.023x10^23
1.55x10^24 = 1.55x10^24/6.023x10^23 = 2.57 moles
this means, 1.55x10^24 atom contains 2.57 moles of carbon
Is the bond length in HCl the same as that in DCl? The wavenumbers of the J = 0 1 rotational transitions for H35Cl and 2H35Cl are 20.8784 and 10.7840 cm–1, respectively. Accurate atomic masses are H = 1.007825 amu, 2H = 2.0140 amu, and 35Cl = 34.96885 amu.

What is the concentration of a strong base solution (of an alkali metal) that has a pH of 11.39?
Answers
Answer:
[tex][OH^-]=2.455x10^{-3}M[/tex]
Explanation:
Hello there!
In this case, since a strong base produce OH ions in solution, it possible to first compute the pOH as shown below:
[tex]pH+pOH=14\\\\pOH=14-pH\\\\pOH=14-11.39\\\\pOH=2.61[/tex]
Thus, via the definition of the pOH we can compute the concentration of the strong base as follows:
[tex]pOH=-log([OH^-])[/tex]
Thus, solving for the concentration we obtain:
[tex][OH^-]=10^{-pOH}=10^{-2.61}[/tex]
[tex][OH^-]=2.455x10^{-3}M[/tex]

A 45 ml sample of nitrogen gas is cooled from 135 degrees celsius to 15 degrees Celsius in a container that can contract or expand at constant pressure. What is the new volume of nitrogen gas?
Answers
Answer:
32 mL
Explanation:
To answer this question we'll use Charles' law, which relates the temperature and volume of a gas at constant pressure:
V₁T₂=V₂T₁
Now we convert the given temperatures to K:
T₁ = 135 °C ⇒ 135 + 273.16 = 408.16 KT₂ = 15 °C ⇒ 15 + 273.16 = 288.16 KAnd given that V₁ = 45 mL, we can input the data:
45 mL * 288.16 K = V₂ * 408.16 KAnd solve for V₂:
V₂ = 32 mLWhat is the electron configuration for

Answer: To be separated using GC, analytes must be volatile.
An air peak is commonly used to determine the dead time when using a TCD detector.
An FID is insensitive to non-combustible gases such as water and carbon dioxide.
A column temperature equal to or slightly above the average boiling point of the sample components results in a reasonable elution time.
Explanation:
The gas chromatography works on the principle of separation of gaseous substances based on the differences of vapor pressure. The thermal conductivity detector works on the principle of detection of effluents from the has chamber and the air peak gives indication of the retention time of the effluents. Flame ionization detector can be used for the detection of organic compounds but insensitive for the detection of halogens, non-combustible substances like carbon dioxide and water. The temperature of the column is kept higher than the average boiling point of the substance so as to attain separation of substances by the differences in the elution time.

What is the concentration of a 500 mL solution with 25 mol of HF? Write your answer with TWO decimal places and round accordingly. ______M
Answers
Answer:
23
Explanation:
The concentration of the solution is given as the ratio of the moles and the volume of the solution. The concentration of hydrogen fluoride is 50 M.
What is molarity?Molarity is the colligative property that is expressed in the terms of the moles of the solute expressed per liter of solution. It is given by the formula:
[tex]\rm Molarity = \rm \dfrac{\text{moles of solute}}{ \text{liters of solution}}[/tex]
Given,
Volume of solution (V) = 0.5 L
Moles of the solute (n) = 25 moles
Molar concentration (M) = ?
Substituting values in the equation we get:
[tex]\begin{aligned} \rm M &= \rm \dfrac{n}{V}\\\\&= \dfrac{25}{0.5}\\\\&= 50\end{aligned}[/tex]
