Answer:
Essential amino acids cannot be made by the body. As a result, they must come from food. The 9 essential amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
Explanation:
The correct answer is option C, the concentration of the hydroxide ion is greater than the concentration of the hydronium ion
Reason -
An acidic solution has an ability to contribute hydrogen ion. Here a hydronium ion (H3O+) has an extra H+ ion along with a water molecule. Thus presence of hydronium ion in larger amount than the hydroxide ion would make the solution acidic. Thus, the concentration of hydroxide ion should be less than the hydronium ion to make the solution a basic solution.
Answer:
No
Explanation:
Replication happens at a much faster rate in prokaryotes than in eukaryotes.
<u>Answer</u>:
Substance A affects the amount of the activation energy needed by the process by catalyzing the reaction. Enzymes are the natural biological catalyst that lowers the activation energy for a reaction to proceed faster at a low energy requirement.
<u>Explanation</u>:
The reactants in the solution react to form a product. For a reaction to happen some energy is needed. The energy which helps reactants to break some bonds and make other bonds to make a product is known as activation energy.
Enzymes are the biological molecules which lower this activation energy by catalyzing the reaction by helping in breaking old bonds and forming new bonds to create a product.
