Answer:
Harshey and chase labeled T2 bacteriophage with radioactive sulfur and radioactive phosphorus. As DNA contains phosphorus, not protein and protein contain sulfur, not phosphorus, therefore, the presence of radioactivity in cell can determine which is the genetic material
.
Then Harshey and Chase infected <em>E.coli</em> with T2 bacteriophage and centrifuged the cell. They found radioactive phosphorus in cell pellet and radioactive sulfur in supernatant.
So by this experiment, they concluded and proved that DNA is the genetic material that gets transfer from one generation to another.
an organism is resistant to a chemical if it has a gene that protects it from the chemical.

Pericardium in the Medical report from Ms. K means fibrous tissue surrounding the heart. The pericardium is the membrane that is enclosing the heart, consisting of an outer fibrous layer and an inner double layer of serous membrane. It is a membrane that surrounds and protects the human heart. It is also a double-walled sac containing the heart and the roots of the vessels. The Pericardial sac has a serious layer and a fibrous layer, total of two layers. This pericardial sac encloses the pericardial cavity which contains pericardial fluid. Pericardium also has a disorders namely Pericarditis, Pericardial effusion, and Cardiac Tamponade.
Atoms are the smallest unit of matter. Atoms of isotopes of the same element contain the same number of protons.
<h3>What are isotopes?</h3>
Isotopes are atoms of the same element which have different numbers of neutrons but the number of protons and electrons remains same.
As the isotopes of the atom have the same number of protons, so, their atomic number will also be the same.
Thus, it can be concluded that atoms of isotopes of the same element contain the same number of protons.
