Which two Characteristics of living things do viruses exhibit
The Correct Answer and Explanation is:
Correct Answer:
The two characteristics of living things that viruses exhibit are:
- They reproduce (but only inside a host cell).
- They contain genetic material (DNA or RNA).
Explanation
Viruses are unique entities that blur the line between living and non-living things. While they do not meet all the criteria required to be classified as living organisms, they do show some characteristics of life, particularly reproduction and the presence of genetic material.
First, viruses reproduce, but in a very specific way—they cannot do it on their own. A virus must infect a living host cell and hijack the cell’s machinery in order to replicate. Once inside a host, the virus uses the cell’s ribosomes, enzymes, and other components to make copies of itself. This ability to reproduce is one of the defining features of life, although viruses only demonstrate it under very specific conditions. Without a host, they remain inert and inactive.
Second, viruses contain genetic material, either in the form of DNA or RNA. This genetic code carries the instructions for making new virus particles and dictates the type of host it can infect. Like living organisms, viruses use this genetic material to pass on information to the next generation during replication. This genetic material can mutate and evolve over time, which explains why viruses like the flu and COVID-19 can change and sometimes become more contagious or resistant to treatments.
However, viruses lack other characteristics of life, such as metabolism (they don’t produce energy or carry out chemical reactions independently), cellular structure (they are not made of cells), and response to stimuli. Because of these limitations, scientists often classify viruses as being on the “borderline” of living and non-living.
In summary, viruses are not fully alive, but they exhibit two major characteristics of living things: the ability to reproduce (inside a host) and the presence of genetic material. These features make them biologically significant and capable of evolving like living organisms.
