What atom is the site of covalent attachment of amc to the model tetrapeptide used in the studies?.
The experiment referenced here involves the use of Y32P-ATP. The atom involved in the site of the covalent attachment is the N atom in Aminomethylcyclohexane (AMC).
The explanation in relation to the attachment of AMC to the Moel Tetrapeptide
Given that Aminomethylcyclohexane (AMC) had been linked around the carboxyl side, it, therefore, means that that type of linkage called the Amide-Linkage (That is N-acylation) can be utilized in the covalent bonding of the fluorophore into the peptide

Which best describes the forces in the nucleus of a stable atom?
O A. The weak nuclear force is greater than the electrostatic force.
O B. The electrostatic force is greater than the strong nuclear force.
O c. The weak nuclear force balances out the strong nuclear force.
O D. The strong nuclèar force balances out the electrostatic force.
Best describes the forces in the nucleus of a stable atom is the strong nuclear force balances out the electrostatic force.
The center region of an atom, which is composed of two different types of particles, is known as the atomic nucleus. Protons with positive charges and neutrons with no charges are present. Because of the strong electrostatic attraction between positively charged protons, atomic nuclei should be unstable, however they occasionally remain stable for more than a billion years.
The stability of nuclei suggests that protons and neutrons are attracted to one another by an attractive force. The strong nuclear force, also known as the residual strong force, is responsible for every individual atomic nucleus' stability. Neutrons and protons are held together by this basic force of nature. It is used to explain the atom's and its nucleus' stability, which is otherwise puzzling. It can be used to explain the origin of all atoms and, consequently, the origin of all known simple and complex molecules.

calculate the oxidation state of the underlined elements of K2 Cr2 O7
-----
Answer:
+4
Explanation:
In PbO2, oxygen exhibits an oxidation number of -2 (since it's not a peroxide or superoxide):
Let the oxidation number of Pb be x. Then, for the compound to be neutral, the oxidation numbers of all atoms should add up to zero.
⇒ x + (−2) + (−2) = 0
x = +4
So the oxidation no. of Pb is +4.

what is emission spectrum and absorption spectrum?
Answer:
When matter interact with EMR then spectrum is obtained. We can understand both spectra using Bohr's hydrogen spectrum. let's have a look on Bohr's hydrogen spectrum what does it say. It says when a electron gains energy it moves from one energy level to other(lower to higher) which is Absorption phenomenon. When the electrons returns from excited state to ground state they emits several spectral lines. this spectrum is called as emission spectrum. inshort the
Emission spectrum is spectrum of electromagnetic radiations that were emitted from the higher energy state(Excited state) to lower energy state(Ground state). and study of emission spectrum is known as AES (Atomic Emission spectroscopy).
When an atom or ion is subjected to EMR, it absorbs certain level of radiations, and when this absorbed energies are studied under spectroscopy they are plotted as absorption spectrum, and study of Absorption spectrum is known as AAS (Atomic Absorption spectroscopy).

If a gas has a volume of 1.25 l at a temperature of 300 k, what will the volume change to if the container is cooled to 200k
The volume of the gas when the container is cooled from a temperature of 300 K to 200 K is 0.83 L
Charles' law
Charles' law states as follow:
V₁ / T₁ = V₂ / T₂
Where
V₁ is the initial volume T₁ is the initial temperature V₂ is the new volume T₂ is the new temperature How to determine the new volumeFrom the question given above, the following data were obtained
Initial volume (V₁) = 1.25 LInitial temperature (T₁) = 300 KNew temperature (T₂) = 200 KNew Volume (V₂) =?V₁ / T₁ = V₂ / T₂
1.25 / 300 = V₂ / 200
Cross multiply
300 × V₂ = 1.25 × 200
Divide both side by 300
V₂ = (1.25 × 200) / 300
V₂ = 0.83 L

Differences in the density of seawater cause it to move. True or false?
True
False
Answer:
True
Explanation:
Differences in water density affect vertical ocean currents (movement of surface ocean water to the bottom of the ocean and movement of deep ocean water to the surface). … Denser water tends to sink, while less dense water tends to rise.
Differences in the density of seawater cause it to move. Therefore, the given statement is true.
What is density?The substance's mass per unit of volume is known as its density (volumetric mass density or specific mass). Although the Roman letter D may also be used, the sign most frequently used for density is (the lower case Greek letter rho). Density is calculated mathematically by dividing mass by volume.
Where m represents the mass, V is the volume, and is the density. Density is sometimes roughly characterized as weight every unit volume, while this is incorrect technically; this quantity is much more precisely known as specific weight. One example of this is in the US oil and gas business. Differences in the density of seawater cause it to move.
Therefore, the given statement is true.
