They would have concluded that the protein coat also entered the bacterial cell and could not deduce that protein is the genetic material.

Explanation:

In their experiment, Hershey and chase found that all the DNA coated with 32 p were missing from the solution as bacteriophage after adsorption on bacterial cell their DNA was transferred to the bacterial cell. The presence of 32 S in the solution shows that the protein coat does not enter the cell during infection.

This way they concluded that DNA is the genetic material and not the protein.

Since phage infecting bacteria inserted their DNA into it and got replicated increasing their number. Also, protein is not involved in their growing numbers.

Hershey and chase have concluded that DNA is not protein it was the genetic material.

Explanation:

Hershey and chase said that DNA is not protein it was the genetic material. They took a direct physical approach in finding the genetic material. They both determined that a protective coat was formed around the bacteriophage.

The internal DNA is not a protein, a genetic material. They used label to find it. The lack of 32p labeled DNA remaining in solution after bacteriohages are allowed to absorb the bacteria showed tha DNA was transferred into the bacterial cell.

The radioactive 35s in the solution shows that protein coat protects the DNA before adsorption.

Blood contains nacl, protein, and cells. the nacl is in a(n) __________, the protein is in a(n) __________, and the cells are in

The answers are solution, colloid, and suspension respectively.

NaCl or salt is dissolved in the blood. So this makes blood and salts a solution. You won't be able to discern the NaCl in a solution of blood and NaCl.

Proteins in the plasma make blood a colloid. Protein particles are bigger than particles in a solution but are smaller than particles in a suspension.

Lastly, blood cells and blood make up a suspension. You would notice this characteristic in blood because red blood cells settle.

You can observe this when your blood is drawn. When it is placed in a test tube and left alone or placed in a centrifuge. The components separate into liquid on top, where you cannot see particles like salt; plasma in the middle, which has pale yellow color and also contains proteins; and the red blood cells at the bottom that settled.

Mammals store Extra glucose in the form of a compound called glycogen. What molecule supplies the energy needed to join glucose

bekas [8.4K]

ATP is the molecule that supplies the energy needed to join glucose molecules together to form a molecule of glycogen.

Explanation:

ATP is the energy currency of cells. It is used to power all non-spontaneous biochemical reactions in the body including the conversion of glucose to glycogen.

Glycogen has a higher Gibbs free energy than glucose (because it lowers entropy) meaning you need energy to convert glucose to glycogen. This reaction does not occur spontaneously because of it akin to ‘climbing a hill’. ATP is involved in the condensation reaction of joining glucose molecules together into glycogen via glycosidic bonds.
