Question

There are several factors that virologists use to classify viruses. Some of these factors include i) type of nucleic acid; ii) presence of an envelope; iii) size and shape of the virus; iv) morphology of the capsid; and v) how the virus reproduces. Lauren, a seasoned animal virologist, has started researching bacteriophages, viruses that are able to infect bacteria. While growing bacteria in the lab, Lauren notices that her samples are not growing properly. She thinks that she may have contaminated her bacterial cultures accidenta. Lauren thinks back through the process of adding the bacteria to the media--perhaps she used a flask that had not been cleaned properly, or the media were contaminated prior to use. The first thing Lauren does is visualize her culture underneath the electron microscope, a microscope powerful enough to magnify the bacteriophage if present. As soon as Lauren begins her microscopy, she notices a small organism that looks like it has a head and legs! Lauren then starts the journey of classifying this virus by recording her observations. Think about the many factors that are used to classify viruses. In order for Lauren to determine the type of virus she may have, she needs to understand some basic concepts about how viruses are characterized?1. Viruses are not capable of metabolic activity on their own; they must have a host cell to reproduce. 2. The intracellular state of a virus is called a virion. 3. The release d leaves is Viruses can have different shapes. vanuses can have dien honora.4. The genetic material of a virus can be DNA or RNA. 5. The genomes of viruses are usually smaller than the genomes of bacteria. 6. Capsids function to surround and protect the nucleic acid core. 7. All viruses have both a capsid and an envelope. 8. Capsids are acquired from the host cell during replication or release.

Answer 1

Answer is option "1"

Explanation:

• Infections are not plants, creatures, or microorganisms, however, they are the quintessential parasites of the living realms. Despite the fact that they may appear living organisms as a result of their gigantic regenerative capacities, infections are not living organisms in the exacting feeling of the word.
• Without a host cell, infections can't complete their life-continuing capacities or recreate. Infections can't produce or store vitality as adenosine triphosphate (ATP), however, need to determine their vitality, and all other metabolic capacities, from the host cell.
• Hence, the right answer is option 1 "viruses are not capable of metabolic activity on their own; they must have a host cell to reproduce."
