Val-Ser-His is an example of
tripeptide (containing three amino acids). As we know proteins are bio-polymers made up of small repeating units called amino acids. Amino acids on condensation reaction produces polypeptides. These polypeptides can be hydrolyzed to its corresponding amino acids when reacted with water in the presence of acid. The tripeptide given in problem upon hydrolysis produces three amino acids i.e.
Valine,
Serine and
Histidine (Figure).</span>
I'm quite sure it's activity level. One other thing that could've been said is metabolism, but that isn't there. However, food is consumed for the body to have energy, and without that energy we wouldn't be able to function. And when we let that intake of food settle, it's stored as fat. But because of activity level, we are capable of burning those calories.

Answer:
Explanation:
When carbon dioxide dissolves and reacts with water, the water and the gaseous reacts to form a dilute mixture solution of (carbonic acid ).
The reaction is
This is a forward reaction. And the symbol shows that the reaction can be reversible. It means that the reaction can be carried in forward direction as well as in the backward direction.
The reaction attains chemical equilibrium until the reactants and the products no longer changes with time.
The carbonic acid can also dissociates into carbon dioxide and water in the backward direction.
Answer:
the true statement is... The pH of the weak acid will be higher than the pH of the strong acid
Explanation:
pH is a measured of the extent to which acids dissociate into ions when plced in aqueous solution.
Strong acid dissociate near-completely, and weak acids barely dissociate.
At equal concentrations, a strong acid will have a lower pH than a weak acid, since the strong one will donate more proton to the solution.
A chemical change is a process which involves the formation new substances from one or more substances. In this case, the new substances have different properties and behaves differently. Therefore, the process that shows a chemical change is when gasoline is burned.
