Answer:
Option C is correct. The flow chart best shows the relationship between the cell structures is:
DNA → gene → chromosome → nucleus
Explanation:
DNA can be described as the material of inheritance.
A gene can be described as the basic unit of inheritance. It is made up of segments of DNA.
Chromosomes can be described as thread-like structures which are made up of different genes.
The nucleus is the site where chromosomes are placed. The nucleus is found in every eukaryotic organism.
Hence, the correct order for these cell structures is illustrated in option C.
Answer: It is necessary for the immune system to clearly distinguish foreign cells and proteins from those made by the body so that the immune system will be able to fight foreign cells and proteins and eliminate them from the body.
Explanation: The ability of the immune system to clearly distinguish foreign cells and proteins from those made by the body helps the body to identify pathogens that invade the body and trigger appropriate immune response to eliminate the foreign cells and proteins.
When the immune system of the body fails to distinguish foreign cells and proteins from those made by the body, the body launches an attack against its cells, that is the immune system triggers an autoimmune response in which attacks are launched against the cells of the body and destroy them. This condition in which the immune system recognizes the cells of the body as non-self and launches an attack against them is known as autoimmunity. Autoimmunity is the major cause of most degenerative diseases such as type I diabetes mellitus.
Hello there.
<span>What amino acid is specified by the codon of GCG, and will there be a change if the codon is changed to GCC?

Carbon dioxide (chemical formula CO2) is a colorless and odorless gas that is vital to life on Earth. This naturally occurring chemical compound is made up of a carbon atom contently double bonded to two oxygen atoms. Carbon dioxide exists in Earth's atmosphere as a trace gas at a concentration of about 0.04 percent (400 ppm) by volume.Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, in ice caps and glaciers and also in seawater. It is present in deposits of petroleum and natural gas.
