For a science fair project, two students decided to repeat the Hershey and Chase experiment, with modifications. They decided to
posledela

Answer:

The correct answer will be option-E

Explanation:

Hershey and Chase's experiment was performed to test whether DNA serves as the genetic material or protein.

To perform experiment they grew bacteriophage into radiolabeled phosphorus and sulfur compounds. The phosphorus is an integral part of the structure of DNA whereas proteins contain sulfur in their structure.  

In the given condition if radiolabeled nitrogen is utilized then the experiment will fail as the structure of proteins also contains an amino group( NH₂) in their structure as well as DNA. The scientist will not be able to identify whether the DNA is the genetic material or protein.

Thus, option-E is the correct answer.

In your own words, explain why a virus such as the rhinovirus, which relies on close contact to spread, might evolve to favor le
Zielflug [23.3K]

Rhinoviruses are transmitted through the air or via contact. We might expect this sort of transmission to require a fairly healthy host (one who gets out and comes into contact with others) and, hence, to select against virulent strains. If we take precautions and try to stay away from people or avoid any contact with people, more hand-washing stations, increased attention to sanitization, and isolation of patients will help to reduce the transmission of the disease and, in the process, may favor the evolution of less virulent strains of the virus.

Alveoli, capillaries, and glomeruli capsules are all lined with simple squamous epithelium. What function is shared by these str
baherus [9]

The common function shared by alveoli, capillaries and glomerular capsules are lined with simple squamous epithelium so they are all involved where absorption  or transport of the materials occur.  The function of the squamous epithelium is mainly selective transmembrane transportation either by using the concentration gradient or by active transport by using the membrane bound carrier proteins.

The pulmonary alveoli are highly vascular in structure and are formed by a layer of the squamous epithelial cells and a network of capillaries.

The capillaries are also made up of squamous epithelial cells and gas exchange between the alveoli and blood vessels occurs through these capillaries.
