A procaryotic cell has five essential structural components: a nucleoid (DNA), ribosomes, cell membrane, cell wall, and some sort of surface layer, which may or may not be an inherent part of the wall.
The gaps (approximately 1 micrometer wide) formed between myelin sheath cells long the axons are called Nodes of Ranvier. Since fat serves as a good insulator, the myelin sheaths speed the rate of transmission of an electrical impulse along the axon.
The macromolecule shown here is an amino acid because of the carbon that bears the amine group and the acid group.
<h3>What is a macromolecule?</h3>
The term macromolecules refers to those molecules that have a large molecular weight. They can mostly be found in biological systems and play various roles in the body

Answer:
can cause cancer.
Explanation:
The DNA damage is mostly repaired by the repair mechanisms present in cells. If DNA damage is not repaired, it can cause a random change in the genetic material of the organism. These changes in the DNA are permanent and are called mutations. Mutations may be adaptive or harmful. Mutations in a protooncogene leading to overproduction of protein to allow uncontrolled cell division can cause cancer. Similarly, a loss of function in tumor suppressor genes also causes cancer.
Answer:
This is because of the presence of a lot of sugar in the diabetic patient's blood stream.
Explanation:
As a test for the presence of simple sugars, Benedict's solution is usually added to the test sample and then heated.
A diabetic patient's body system has a lot of sugar flowing around in the blood stream. His body is unable to get this sugar into the cells for use, because the insulin produced by his pancreas is not enough. As a result his body system has a lot of sugar.
Consequently, whenever the patient urinates, the urine has a high sugar content as opposed to a normal person, whose urine has a low sugar content because of a normal functioning body system.
The high sugar content of the diabetic patient's urine is what gives an intense brick red precipitation with Benedict's reagent.
