The diagram shows an experiment on the digestion of the protein in egg albumen by protease.
laila [671]

Answer:

<u>C</u>. containing

  • <u><em>egg albumen </em></u>
  • <u><em>protease </em></u>
  • <u><em>dilute  hydrochloric  acid</em></u>

Explanation:

A protease is a kind of peptidase enzyme that breaks down proteins into peptide molecules. As a digestive enzyme it is located in the lining of the stomach where, relative to the hydrochloric acid in digestive juices, the pH is usually low/ acidic.

<em>Enzymes speed up reaction rates by </em><em>providing alternative pathways</em>. By modifying the enzyme composition, supplying more collision energy, and changing the collisions between and the ratio of reactants, certain variables will increase the reaction rate.

Proteases function well at 37℃, the typical internal temperature of the human body- this temperature provides adequate energy for the reaction. Similarly, proteases require low pH for the correct configuration, and beyond this pH and temperature, they may become denatured or simply not function well as catalysts.

When you hear the term mutation, you usually think of change. But how do mutations influence traits that may be inherited?
lana [24]

Hereditary mutation - may be passed to another generation, occurs in gametes, variation that may enhance survival.

Somatic mutation - not passed from generation to generations, occurs in body cells.

Both- changes in DNA.

<h3><u>Explanation:</u></h3>

Mutations are defined as sudden changes in DNA that takes place by changing a particular nucleotide or a portion of DNA, or even a whole chromosome which has potential to change characters of an organism. Mutation was first proposed by Hugo de Vries who is also known as the Father of Mutation Theory.

Mutations can occur in any cell of body. It may occur in somatic cells, or in germ mother cells. But the mutations that occur in germ mother cells are actually the mutations that are carried forward by the gametes into next generations. Mutation in somatic cells get obliterated as the organism dies. And the Mutation in gamete cells are those mutations which are capable to cause variations in progenies which can led to better survival of the progenies.
