Dietary protein will not be digested if Hcl were not being produced in sufficient quantities.
In the stomach, there are some glands found on the stomach lining that helps to release hydrochloric acid (HCl). Their major role is to dissolve food and produce an acidic medium.
The acidic media promotes and improves the conversion of pepsinogen to pepsin. Pepsin acts as an enzyme that supports protein digestion.
Protein digestion requires a pH of around 1.8 which can be achieved by the secretion of HCl.
As a result, if HCI is not released in the stomach in sufficient quantities, pepsin will not be activated and it would have a detrimental impact on protein digestion.
Therefore, we can conclude that dietary protein will not be digested if Hcl were not being produced in sufficient quantities.

B. can dissolve only a specific amount into the liquid, determined by its solubility.
C. can dissolve only a specific amount into the liquid, determined by the liquid's solvent point.
D. can dissolve any amount into the liquid, as long as the liquid is being heated.
When a substance is soluble it can dissolve only a specific amount into the liquid, determined by its solubility. Hence, option B is correct.
What is the solute?A solute is something being dissolved, a solvent is a thing dissolving the item, and the solution is the mixture of the two items.
Solubility is a term used to describe how readily a substance can be dissolved in a solvent to form a solution. Thus, a substance is said to be soluble if it dissolves completely in a solvent and insoluble if it doesn't dissolve or only dissolves partially.
Hence, when a substance is soluble it can dissolve only a specific amount into the liquid, determined by its solubility.

why is it important to select a good stationary phase
Selectivity is relatively easy to alter, with mobile phase composition and stationary phase being the primary means of adjustment. The hydrophobicity, polarity and nature of the chosen stationary phase all play a crucial role in analyte interaction and directly affect the selectivity of a separation.
In chromatography, it is important to select a good stationary phase so as to ensure proper separation of components.
What is chromatography?Chromatography is a separation technique which is generally used for separating substances based on their solubilities. The technique makes use of two phases the mobile phase and the stationary phase.
The components are separated from each other based on their solubility in the mobile phase. Component which is least soluble does not travel along the mobile phase while component which is highly soluble travels with the mobile phase.
The difference in the solubility of the components is measured with the reference to the solvent front and is expressed in terms of Rf value.Chromatography finds application in forensics, separation of organic compounds,etc.

Why do atoms exchange or share electrons during bonding?
to obtain a full outer electron shell
to attract an ion with the opposite charge
to become neutral
to have eight inner level electrons
Answer:
to obtain a full outer shell
Explanation:
The atoms of some elements share electrons because this gives them a full valence shell. ... If atoms can't achieve a full outer shell by transferring electrons, they resort to sharing. In this way, each atom can count the shared electrons as part of its own valence shell. This sharing of electrons is covalent bonding.
Atoms generally exchange or share electrons during bonding because they want to obtain a full outer electron shell. Thus, the correct option for this question is A.
What is Chemical bonding?Chemical bonding may be defined as a type of interaction that is significantly accomplished through the association of atoms into molecules, ions, crystals, and other stable species that make up familiar substances.
According to the context of this question, the atoms of some elements typically transfer their electrons to the other elements in order to achieve a fully filled outermost shell.
If they do not have a tendency of transferring, they follow a different mechanism of sharing their electrons. The sharing of electrons gives rise to the formation of covalent bonding.
Therefore, atoms generally exchange or share electrons during bonding because they want to obtain a full outer electron shell. Thus, the correct option for this question is A.
