what would happen to dietary protein if hcl were not being produced in sufficient quantities?
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.

during June , earth is 152,000,000km from the sun. how far is earth from the sun in miles
Answer:
94448421.2201
Explanation:
multiply the value in kilometers by the conversion factor '0.62137119223684'.
So, 152000 kilometers = 152000 × 0.62137119223684 = 94448.42122 miles.

Give the correct order of apparatus (Crucible, Filter funnel, Test tube, Dropper, Spatula) to show the correct arrangement that can be used to prepare and investigate the nature of pH of a sample of onion solution.
Answer:
Is it Crucible,Test tube,Dropper,Filter funnel, Spatula
Explanation:
The laboratory apparatus is used to experiment with the chemicals and to hold them. To prepare and investigate the pH of the onion sample apparatus required are the crucible, test tube, dropper, filter funnel, and spatula.
What is pH?pH is the measurement of the hydrogen or the hydroxide ion concentration in the solution to determine the alkaline or acidic nature of the substance.
The pH of the onion solution can be determined by experimenting with the help of the laboratory apparatus and reagents. A crucible is a container that can withstand high temperatures.
A test tube is a glassware used to hold the substance or chemical in it. Similarly, a dropper is used to draw liquids. The filter funnel separates the filtrate or the solution. A spatula can be used to remove or add the substance.
Therefore, the correct order of the apparatus is the crucible, test tube, dropper, filter funnel, and spatula.

For homogeneous:
Filteration, vaporization, and a reverse chemical reaction
Explanation:
1) precipitation/crystallization reactions - if one of the components can form a solid salt when the solution undergoes several factors (concentration change, temperature change, etc); separation can be done either by filtration, centrifugation, or simple decantation.
(2) chromatography - separation can be based on the mobility of the phases (liquid chromatography, gas chromatography, ion-exchange, etc.)
(3) solvent extraction - if the components are both liquid, separation based on their relative solubilities
(4) distillation - separation based on different boiling points.
(5) magnetic separation - if one of the components have magnetic properties.
(6) electrophoresis - separation of organic molecules based on the type of gel used
