Answers
Physical crowding and loud noise are considered sources of environmental stressors and are linked to the incidence of increased stress hormones.
High concentration of cytoskeletal filaments, organelles, and proteins along with the space constraints due to the axon’s narrow geometry lead inevitably to intracellular physical crowding along the axon of a neuron. . Molecular motors that mediate active transport share movement mechanisms that allow them to bypass physical crowding present on microtubule tracks. Everyday loud noise typically do not damage your hearing. However, many people participate in activities that produce harmful sound levels, which repeated over time will cause hearing loss.

When slip occurs in a material, the critical resolved shear stress (CRSS) is used to determine the minimum shear stress required to start the slip.
Given that a tensile stress is applied on a nickel crystal along a 1011 direction, and slip occurs on a (111) plane and in a (101) direction, the critical resolved shear stress will be computed as follows: Calculation for g[000] Since the tensile stress is applied along the 1011 direction, g[000] = 0.Calculation for g[1012]:The direction of slip (101) lies in the (1012) plane.

how can offspring have traits that neither parent has?
Answers
When both parents shared different traits either it will be heterogeneous or homogenous traits,in that case offspring traits neither belongs to parents.However,chances are very that traits of children neither belongs to parents.
Unaffected parents can create impacted offsprings assuming that the two guardians are transporters (heterozygous) for the attribute being followed in the family. Latent traits are normally not communicated in each age. Finally, guys and females are similarly prone to communicate a latently acquired characteristic.
In the event that the latent characteristic is more than prevailing, the recessive traits will really become predominant and the predominant attribute will become recessive.Recessive alleles are meant by a lowercase letter (a versus A). Just people with an aa genotype will communicate a latent characteristic; consequently, posterity should get one passive allele from each parent to display a latent traits.

Consider the following chemical reaction: 3 MgCl2 + 2 Na3PO4 6 NaCl + Mg3(PO4)2. Assume that 0.75 mol of MgCl2 and 0.65 mol of Na3PO4 are placed in a reaction vessel.
a) Verify that Na3PO4 is the excess reactant and MgCl2 is the limiting reactant.
b) How many moles of the excess reactant are left over after the reaction stops?
c) How many moles of NaCl will be produced in this reaction? (Remember—you must base this answer on how many moles of the limiting reactant that reacted.)
Answers
Answer:
To determine the limiting reactant and the excess reactant, we need to compare the stoichiometry of the reaction with the amounts of each reactant given.
The balanced chemical equation is:
3 MgCl2 + 2 Na3PO4 -> 6 NaCl + Mg3(PO4)2
Given:
Moles of MgCl2 = 0.75 mol
Moles of Na3PO4 = 0.65 mol
a) To verify the limiting reactant, we need to calculate the moles of Na3PO4 and MgCl2 needed to react completely, based on the stoichiometry of the balanced equation.
From the equation, we can see that:
For every 3 moles of MgCl2, 2 moles of Na3PO4 are required.
Therefore, the moles of Na3PO4 required to react with 0.75 mol of MgCl2 would be:
(0.75 mol MgCl2) x (2 mol Na3PO4 / 3 mol MgCl2) = 0.5 mol Na3PO4
Since we have 0.65 mol of Na3PO4, which is greater than the required amount of 0.5 mol, Na3PO4 is the excess reactant.
b) To find the moles of the excess reactant left over, we subtract the moles of Na3PO4 that reacted from the initial moles:
0.65 mol Na3PO4 - 0.5 mol Na3PO4 = 0.15 mol Na3PO4 (left over)
c) To determine the moles of NaCl produced in the reaction, we need to calculate the moles of the limiting reactant (MgCl2) that reacted. From the balanced equation, we know that:
For every 3 moles of MgCl2, 6 moles of NaCl are produced.
Using the stoichiometry, we can calculate the moles of NaCl produced:
(0.75 mol MgCl2) x (6 mol NaCl / 3 mol MgCl2) = 1.5 mol NaCl
Therefore, 1.5 mol of NaCl will be produced in this reaction.
A ruby laser produces red light that has a wavelength of 5.00 × 10^-7 m. Calculate its energy in joules
Answers
Answer:
The energy of a ruby laser that produces red light with a wavelength of 5.00 × 10^-7 m is 3.98 × 10^-19 J.
Explanation:
The energy of a photon is given by the formula E = hf where h is Planck’s constant and f is the frequency of the photon. The frequency of the photon can be calculated using the formula f = c/λ where c is the speed of light and λ is the wavelength of the photon.
Substituting the given values, we get:
f = c/λ = 3.00 × 10^8 m/s / 5.00 × 10^-7 m = 6.00 × 10^14 Hz
E = hf = (6.626 × 10^-34 J s) × (6.00 × 10^14 Hz) = 3.98 × 10^-19 J
Therefore, the energy of a ruby laser that produces red light with a wavelength of 5.00 × 10^-7 m is 3.98 × 10^-19 J.

Br belongs to 17 or 7A. That means that it has 7 valence electrons.
Our molecule is PBr₃. One molecule of it has 1 atom of P and 3 atoms of Br. Each atom of Br has 7 valence electrons and the atom of P has 5 valence electrons.
Electron count = 1 * 5 + 3 * 7
Electron count = 26 valence electrons.
A 4.5-cm-diameter, 0.50-mm-thick spherical plastic shell holds carbon dioxide at 2.0 atm pressure and 25∘C. CO2 molecules diffuse out of the shell into the surrounding air, where the carbon dioxide concentration is essentially zero. The diffusion coefficient of carbon dioxide in the plastic is 2.5×10−12 m2/s What is the diffusion rate in molecules/s of carbon dioxide out of the shell? Express your answer in molecules per second. Part B If the rate from part A is maintained, how long in hours will it take for the carbon dioxide pressure to decrease to 1.0 atm ? The actual rate slows with time as the concentration difference decreases, but assuming a constant rate gives a reasonable estimate of how long the shell will contain the carbon dioxide. Express your answer in hours.
Answers
The diffusion rate of carbon dioxide out of the shell can be calculated using Fick's first law of diffusion, which states that the diffusion rate is proportional to the diffusion coefficient, the surface area, and the concentration difference.
First, we need to calculate the surface area of the shell:
The diameter of the shell is given as 4.5 cm, so the radius is half of that, which is 2.25 cm.
The surface area of a sphere is given by the formula A = 4πr^2.
Plugging in the radius, we get A = 4π(2.25 cm)^2 = 63.59 cm^2.
Next, we need to calculate the concentration difference:
The carbon dioxide concentration inside the shell is given as 2.0 atm, while the concentration outside the shell is essentially zero. The concentration difference is therefore 2.0 atm - 0 atm = 2.0 atm.
Now we can calculate the diffusion rate using the formula diffusion rate = diffusion coefficient * surface area * concentration difference. Plugging in the given values, we get diffusion rate = (2.5×10^(-12) m^2/s) * (63.59 cm^2) * (2.0 atm) = 3.18×10^(-9) cm^3·atm/s.
To convert this to molecules per second, we need to use Avogadro's number, which is 6.022×10^23 molecules/mol. Since carbon dioxide has a molar mass of approximately 44 g/mol, we can convert the diffusion rate to molecules per second by multiplying it by Avogadro's number and dividing by the molar mass of carbon dioxide. The molar mass of carbon dioxide is 44 g/mol = 44000 mg/mol.
diffusion rate (in molecules/s) = (3.18×10^(-9) cm^3·atm/s) * (6.022×10^23 molecules/mol) / (44000 mg/mol) = 4.34×10^14 molecules/s.
So, the diffusion rate of carbon dioxide out of the shell is 4.34×10^14 molecules/s.
For Part B, we can use the diffusion rate from Part A to calculate the time it takes for the carbon dioxide pressure to decrease to 1.0 atm.
The initial pressure is 2.0 atm and the final pressure is 1.0 atm.
Since the rate is constant, we can use the formula time = (final pressure - initial pressure) / diffusion rate.
Plugging in the values, we get time = (1.0 atm - 2.0 atm) / (4.34×10^14 molecules/s) = -2.3×10^(-15) s.
To convert this to hours, we divide by 3600 s/hour and take the absolute value to get time = |(-2.3×10^(-15) s) / (3600 s/hour)| = 6.4×10^(-19) hours.
So, it will take approximately 6.4×10^(-19) hours for the carbon dioxide pressure to decrease to 1.0 atm, assuming a constant diffusion rate.

Answers
The solution that would be expected to contain the greatest number of solute particles is 1 liter of 1.0 m NaCl. Option C is the correct answer.
Ionic compounds are chemical compounds composed of ions held together by electrostatic forces of attraction between oppositely charged ions.
When an ionic compound such as NaCl is placed in water, the component atoms of the NaCl crystal dissociate into individual sodium ions (\(\rm Na^+\)) and chloride ions (\(\rm Cl^-\)).
To determine which of the solutions would be expected to contain the greatest number of solute particles, we need to consider the number of solute particles produced by each molecule of the solute.
NaCl dissociates in water to produce two solute particles (\(\rm Na^+\)and \(\rm Cl^-\)), while glucose does not dissociate and therefore produces only one solute particle. Therefore, 1 liter of 1.0 m NaCl would contain twice as many solute particles as 1 liter of 1.0 m glucose.
In conclusion, 1 liter of 1.0 m NaCl solution would be expected to contain the greatest number of solute particles. The correct answer is option C.
