The binding of the amino acid in aminoacyl-tRNA involves the formation of an ester bond.  Option b

Aminoacyl-tRNA is a complex molecule that plays a crucial role in protein synthesis. It consists of a tRNA molecule covalently linked to an amino acid. The amino acid is attached to the 3' end of the tRNA molecule through an ester bond.

An ester bond is formed between the carboxyl group (-COOH) of the amino acid and the hydroxyl group (-OH) of the ribose sugar at the 3' end of the tRNA molecule. This ester bond is also referred to as an ester linkage. The formation of the ester bond is catalyzed by the enzyme aminoacyl-tRNA synthetase.

The ester bond in aminoacyl-tRNA is essential for protein synthesis. During translation, the aminoacyl-tRNA molecule carries the specific amino acid to the ribosome, where it is incorporated into the growing polypeptide chain. The ester bond is later hydrolyzed, releasing the amino acid for further use in protein synthesis.

In summary, the binding of the amino acid in aminoacyl-tRNA involves the formation of an ester bond between the carboxyl group of the amino acid and the hydroxyl group of the ribose sugar in the tRNA molecule.

Explanation:

Edge.

Answer:

1.1 mol of O2

Explanation:

First we need the balance chemical equation which is

2 H2O2 -------> 2 H2O + O2

This is important because in stoichiometry you can go from units of one thing to other by using mole ratios, here the mole ratio is 2 mol of H2O2  for one mole of O2.

\(2.2 mol H2O2 \frac{1mol O2}{2 mol H2O2}\) = 1.1 mol of O2

Answer:

5.9 grams

Explanation:

You need 2 faraday to deposit 1 mole of Ni (59 grams) because there are 2 moles of electrons in equation:

Ni+2 + 2e- --> Ni(s)

So, 0.2 faraday will deposit 1/10 of that or 5.9 grams of Ni(s).

The sample, having a half-life of 20000 years, is 40000 years old.

Half-life is the time it takes for a substance, such as a radioactive isotope, to decrease to half of its initial amount. The concept of half-life is used to describe how quickly a substance decays or is used up. It is an important concept in many fields, including chemistry, biology, and physics.

If a crystal contains a radioactive isotope that has a half-life of 20000 years, then the amount of the sample is reduced to half every 20000 years.

Since 1/4 of the parent isotope remains, and 1/4 is halved two times, then two half-lives have passed. And so, the sample is 40000 years old.

The total energy required to change 10 grams of ice at zero degrees Celsius to steam at 100 degrees Celsius is 800 + 1000 + 5400 = 7200 calories.

To change 10 grams of ice at zero degrees Celsius to steam at 100 degrees Celsius, we need to calculate the energy required to melt the ice, heat the resulting water to its boiling point, and then convert it into steam.

First, we need to calculate the energy required to melt the ice, which can be done using the latent heat of fusion of H2O, which is 80 cal/g. So, the energy required to melt 10 grams of ice would be 10 grams * 80 cal/g = 800 calories. Next, we need to heat the resulting water to its boiling point. The specific heat of water is 1 cal/g, and we need to raise the temperature of 10 grams of water from 0 degrees Celsius to 100 degrees Celsius, so the energy required would be 10 grams * 100 degrees Celsius * 1 cal/g = 1000 calories. Finally, we need to convert the water into steam, which requires the latent heat of vaporization of H2O, which is 540 cal/g. So, the energy required would be 10 grams * 540 cal/g = 5400 calories.

Therefore, the total energy required to change 10 grams of ice at zero degrees Celsius to steam at 100 degrees Celsius is 800 + 1000 + 5400 = 7200 calories.

The Arrhenius equation is given by k = Ae^(-Ea/RT), where A is the frequency or preexponential component and e^(-Ea/RT) is the percentage of collisions with energy sufficient to break through the activation barrier at temperature T.

The Arrhenius equation in physical chemistry is a formula for the temperature dependence of reaction rates. Based on the research of Dutch chemist Jacobus Henricus van 't Hoff, who had noted in 1884 that the van 't Hoff equation for the temperature dependence of equilibrium constants suggests such a formula for the rates of both forward and reverse reactions, Svante Arrhenius proposed the equation in 1889.

This equation has numerous and significant applications in calculating the energy of activation and the rate of chemical reactions. Arrhenius explained and justified the formula using physical principles. The best way to view it right now is as an empirical relationship.

It can be used to simulate a wide range of thermally induced processes and reactions, including the temperature variation of diffusion coefficients, the population of crystal vacancies, creep rates, and many more. The 1935-created Eyring equation also explains the connection between rate and energy.

Explanation:

The increase in pressure when a basketball is pumped up is caused by the change in the number of molecules (optionC).

When air is pumped into a basketball, the air molecules are forced into a smaller space, which increases the number of molecules in that space. This increase in the number of molecules leads to an increase in the pressure of the gas within the ball.To better understand why this is the case, we can use the ideal gas law, which describes the behavior of gases under various conditions. The ideal gas law is expressed as PV = nRT, where P is pressure, V is volume, n is the number of molecules, R is the gas constant, and T is temperature.
When air is pumped into a basketball, the volume of the ball remains the same (assuming the ball is rigid and does not expand), and the temperature of the air inside the ball does not change significantly. Therefore, according to the ideal gas law, the only way the pressure can increase is if the number of molecules (n) increases.
This increase in pressure is what makes the ball bouncy and allows it to be used for games and activities. It is important to note that overinflating a basketball can lead to a rupture or bursting of the ball due to the excessive pressure created by the increased number of molecules.

Melting point

Explanation:

Pure substances have sharp melting and boiling points while impurities lower the melting point and raise the boiling point

In an aqueous solution, the hydrate that forms the most is the one with the greatest stability. Therefore, the greater the stability of the hydrate, the more it forms in an aqueous solution. Therefore, the ketone that forms the most hydrate in an aqueous solution is acetone.

Water molecules tend to be associated with the carbonyl group of the ketones through hydrogen bonds. The hydrate with the greatest stability is the one that has the most extensive hydrogen bonding network. Ketones have a more polar nature than alkanes. Because of this, they can interact more effectively with the polar water molecules in the surrounding environment. The degree of solvation of the carbonyl group increases when the size of the alkyl substituents of the ketones grows. In addition, the reactivity of the carbonyl group diminishes as the size of the alkyl substituents increases, lowering the capacity of the carbonyl group to interact with water molecules.
