Based on the solubility observations, which of the following pairs of cations could be distinguished by the addition of sodium chloride to the solutions?iron and calcium.

After the amino acid chain leaves the ribosome, Endoplasmic Reticulum folds, modifies, and transports the protein.

The Golgi apparatus, also known as the Golgi complex, serves as a factory where proteins from the ER are further processed and sorted before being transported to their final destinations: lysosomes, the plasma membrane, or secretion. The endoplasmic reticulum (ER) is a large, dynamic structure in the cell that performs numerous functions such as calcium storage, protein synthesis, and lipid metabolism. The ER's various functions are carried out by distinct domains, which include tubules, sheets, and the nuclear envelope.

Endoplasmic reticulum is classified into two types: Rough Endoplasmic Reticulum: Their primary function in cells is to produce proteins, and ribosomes are attached to their surface. Smooth Endoplasmic Reticulum: Their primary function in the liver and kidney cells is to produce lipids and detoxify toxins in the body.

Therefore, the chain of amino acids, after they leave the ribosomes, they are found in the endoplasmic reticulum and the further reaction takes place to complete the whole process which the endoplasmic reticulum is responsible for.

Caesium(Cs) is the most reactive alkali metal in the group I than the francium due to the atomic radius, effective nuclear charge and the ionization energy of the caesium element.

Ionization energy is the energy requires to remove valence electron from the outer orbital. As we goes down the group, the ionization energy is decreased. This is occurred because as we goes down the group, the distance between outermost orbital and nucleus is increased. Therefore, it has lower ionization energy than other elements in the group.

Atomic radius of the element is the distance between the nucleus and the electron present in the outermost orbital. As we goes down the group, atomic radius is decreased. Therefore, it easily donates electrons and due to this, caesium is more reactive.

Fracium is really heavy element and there are many positive charges present in the nucleus of the francium. Due to the presence of more positive charges, electrons in the francium revolve at a speed of light. The electrons in the francium are closer to the nucleus than the caesium and it is harder to remove valence electrons in the caesium.

The option that best describes how to correct the Wiliam error, is The third result, should state that the kinetic energy of the ejected electrons depends only on the frequency of the photons. Correct answer: letter D.

Since, the best way to correct Wiliam's error is to edit the third result to state that the kinetic energy of the ejected electrons depends only on the frequency of the photons. This can be done by replacing the existing sentence with the new sentence, or simply adding it as an additional statement.

The photoelectric effect, first explained by Albert Einstein in 1905, is the phenomenon in which electrons are emitted from the surface of a metal when light of a certain frequency, or energy level, is shone upon it.

The photoelectric effect was first observed by William Hallwachs in 1887. Hallwachs observed that when light was shone on a metal, an electric current was produced. This current was proportional to the intensity of the light and independent of its frequency, leading him to conclude that the energy of the light was being transferred to the electrons in the metal.

Before paring first the electrons go into an empty orbital. Due to the negative charge of electrons, electrons are attracted to one another. To reduce repulsion, the electrons do not share orbitals.
