Question Compare a virus to a unicellular organism.(1 point) Responses Neither unicellular organisms nor viruses respond to stimuli. Neither unicellular organisms nor viruses respond to stimuli. Unicellular organisms have a cell membrane made from a lipid bilayer; viruses have a protein coat. Unicellular organisms have a cell membrane made from a lipid bilayer; viruses have a protein coat. Viruses reproduce through asexual reproduction; unicellular organisms need a host cell. Viruses reproduce through asexual reproduction; unicellular organisms need a host cell. Viruses need energy; unicellular organisms do not need energy.

Unicellular organisms obtain and utilize energy through various metabolic processes, while viruses do not have their own metabolism and rely on host cells for energy.

I apologize for any confusion, but viruses actually do not need energy. Viruses are considered non-living entities that depend on host cells to replicate and carry out their life cycle. On the other hand, unicellular organisms, such as bacteria or protozoa, do require energy for their own processes and survival.

To compare a virus to a unicellular organism, we can look at several characteristics.

1. Responsiveness to stimuli: Neither unicellular organisms nor viruses respond to stimuli. They lack a complex nervous system and do not exhibit behaviors like movement or response to external signals.

2. Cell structure: Unicellular organisms have a cell membrane made from a lipid bilayer, which forms a boundary and controls what enters and exits the cell. On the other hand, viruses lack a true cell structure. They consist of genetic material (such as DNA or RNA) enclosed in a protein coat called a capsid.

3. Reproduction: Viruses reproduce through a process called asexual reproduction. Rather than independently reproducing, they need to infect a host cell and hijack its machinery to replicate themselves. In contrast, unicellular organisms reproduce independently through processes such as binary fission (division of one cell into two identical cells) or budding (a smaller cell grows out from the parent cell).

4. Energy requirements: Viruses do not require energy on their own as they are essentially genetic material packaged in a protein coat. They rely on host cells to provide the energy and resources for their replication. Unicellular organisms, however, are capable of obtaining and utilizing energy for their own cellular activities.

By considering these characteristics, we can differentiate between viruses and unicellular organisms and understand the key differences between them.
