12. Cows digest proteins into smaller molecules called peptides through the use of an enzyme called pepsin. Aqueous solutions taken from the contents of a cow's stomach are found to have many more hydrogen ions
(H+) than hydroxide ions (OH-). A veterinarian is attempting to conduct an experiment that mimics protein
digestion and has the following four test tubes set up. Which would you expect to have the greatest
concentration of peptides?
(A) Test tube 1: protein and pepsin in water at pH 1.4
(B) Test tube 2: protein and pepsin in water at pH 8.2
(C) Test tube 3: protein in water at pH 7.6
(D) Test tube 4: pepsin in water at pH 1.7

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.

your answer is going to be physical weathering

there is not 1 highest source of protein, but there are many; meats, fish, poultry, seafood, cheese, eggs, yogurt and milk. the only non complete animal food that is beneficial is gelatin.

sorry if this did not , have a great day!
