On the laboratory bench right in front of you, there is a bone. You can tell that it has an articular surface that is smooth and just slightly concave. This skeletal feature would be referred to as a Facet.
<h3>What is the composition of human bone?</h3>
A transcription factor collagen forms the structure of bones, and calcium phosphate, a mineral, gives the framework strength and hardness. When other body parts require calcium, bones release some of the calcium they have stored into the blood.
<h3>Why are bones so durable?</h3>
A living, developing tissue is bone. Collagen, a polypeptide that provides a soft structure, and calcium, a mineral that gives strength and hardness, make up the majority of its composition. Together, these factors give bone the strength and flexibility it needs to withstand stress.

Colonization of aerobic coliform and Bacteroides
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.
Yes they do have a cell wall
