Answer:
From smallest to largest, the levels are species, genus, family, order, class, phylum, and kingdom. Each of the ranking levels is called a taxon. Just as a genus is a group of similar species, a family is a group of similar genera. An order is a group of similar families.
Answer: The correct answer is-
an agent that causes a mutation in DNA.
Mutagen is an agent or a substance that causes permanent change in the genetic material of living organisms ( DNA, deoxyribonucleic acid). This process is called mutation.
A mutagen can be a chemical, physical or biological agent that causes mutation in the DNA.
Example- Physical agents such as -
- Ionizing radiations like alpha particles, gamma rays, X-rays that brings break in the DNA and cause other damages.
- Ultraviolet radiations that creates pyrimidine dimers ( T=T) and causes replication errors if damage is not repaired.
The characteristics that apply to viruses are;
- Viruses are made of RNA or DNA.
- Viruses have a protein coat
<h3>What are viruses?</h3>
Viruses are microscopic non-cellular structure consisting of a core of DNA or RNA (nucleic acid) surrounded by a protein coat (capsid).
A virus is considered as by non-living because it requires a living host cell to replicate, and often causes disease in the host organism.
Therefore, the characteristics that apply to viruses are;
- Viruses are made of RNA or DNA.
- Viruses have a protein coat
