Answer;

-The secondary and tertiary structure of the enzyme.

Explanation;

-Lactase is an enzyme that is found in the small intestine, liver, and kidney of mammals. In the presence of lactase, lactose is cleaved and reduced to its subunits D-galactose and D-glucose, monosaccharides that can eventually be utilized as a source of energy in cells.

-At extremely low pH, molecules move so slowly that reaction rates can be hampered even though the enzyme is still properly folded and active. At extremely high pH, bonds and interactions that exist between the amino acid side chains (R groups) in an enzyme become disrupted. The result is that the enzyme is incapable of maintaining its shape, and therefore unfolds, becoming inactive.

Predict how many double helical molecules of dna will be present in the gametes of the fruit fly, drosophila, a diploid organism
anygoal [31]
The answer is four double-helical molecules of DNA, which match up to four unreplicated chromosomes. In addition, for fruit fly gametes the haploid number is 4 in which can be written as N = 4. The meiosis is a procedure in which the amount of chromosomes per cell is cut in partial in excess of the parting of homologous chromosomes in a diploid cell.

What is the correct answer for number 14 ? Explain why please !!
pshichka [43]

2) The concentration of O2 will increase inside the cell.


The cell will want to reach equilibrium, meaning that there should be an equal number of oxygen inside and outside the cell.  In the picture, more oxygen is shown outside the cell than inside so oxygen will flow into the cell until it has reached equilibrium.  Therefore, the concentration of O2 will increase in the cell.


Hope this helps!!
