What type of reproduction a virus have?
Viruses reproduce through a process called replication, which occurs only within a host cell. They attach to the host cell and inject their genetic material (DNA or RNA), hijacking the cell's machinery to produce new viral components. Once assembled, new viruses are released, often killing the host cell in the process. This method of reproduction is not considered sexual or asexual in the traditional sense, as viruses require a host for replication.
Viruses make the host cell produce new viruses which kills th host cell?
Yes, viruses hijack the host cell's machinery to replicate themselves, eventually causing the cell to burst and release new viruses. This process, known as lysis, results in the death of the host cell.
Why virus is always parasitic?
Viruses are considered parasitic because they require a host cell to replicate and reproduce. They hijack the host cell's machinery to make copies of themselves, which can harm the host cell in the process. This dependence on a host cell for replication is why viruses are often classified as obligate intracellular parasites.
What causes viruses to form?
Viruses have to come from a source (Chain of Infection: Source, Portal of Exit, Mode of Transmission, Portal of Entry, Susceptible Host) but the thing about Viruses is that once you have them they're there for good. Often they remain latent and only raise their head if the host is run down, stressed, mal-nourished...
Do viruses reproduce inside host cells causing them to burst?
Yes, viruses can reproduce inside host cells by hijacking the host cell's machinery to make copies of themselves. This can cause the host cell to burst, releasing the newly formed viruses to infect other cells.
How do viruses adapt?
Viruses can adapt through mutations in their genetic material, allowing them to evolve and develop new characteristics. This can occur during replication inside host cells or through recombination with other viruses. Adaptation enables viruses to overcome immune responses, change host range, or develop resistance to antiviral treatments.

How can viruses eat?
Viruses cannot eat because they lack the cellular machinery for metabolism. Instead, viruses hijack host cells and use their machinery to replicate themselves. This process often damages or destroys the host cell.
Why are viruses often considered to be nonliving entities despite their ability to replicate and infect host cells?
Viruses are often considered nonliving because they lack the ability to carry out essential life processes on their own, such as metabolism and growth. They can only replicate and infect host cells by hijacking the cellular machinery of the host.
Phages or viruses that go through the lysogenic virus cycle?
Phages are also known as bacteriophages which are viruses. They are specifically viruses that attack bacteria. Depending on the species, some viruses incorporate their DNA in to the host's genome. These viruses are known as proviruses because they can go through the lysogenic cycle.
Why most viruses that infect bacteria have tails whereas most viruses that infect animals and plants do not?
Bacterial viruses, or bacteriophages, often have tails to help them attach to specific receptors on the bacterial cell surface. Animal and plant viruses typically do not need tails because they enter host cells through different mechanisms, such as membrane fusion or endocytosis. The diversity of host organisms and cell types likely contributes to the variety of viral structures seen across different types of viruses.
Viruses make the host cell produce new viruses which kills th host cell?
Yes, viruses hijack the host cell's machinery to replicate themselves, eventually causing the cell to burst and release new viruses. This process, known as lysis, results in the death of the host cell.
Do Most DNA viruses multiply in the host cell's cell membrane?
No, DNA viruses multiply in the host cell's nucleus, while most RNA viruses multiply in the host cell's cytoplasm
What are 4 ways viruses spread from one host to another?
Viruses can spread from one host to another through various means, including: Direct Contact: Physical interaction with an infected individual, such as touching or kissing, can transmit viruses. Airborne Transmission: Viruses can be released into the air through coughs or sneezes, leading to inhalation by others. Vector-borne Transmission: Some viruses are spread by vectors, like mosquitoes or ticks, which carry the virus from one host to another. Fomites: Viruses can survive on surfaces, and touching contaminated objects followed by touching the face can facilitate transmission.

Why can't viruses reproduce out of they're host organism?
Picture the host as the viruses brain and heart.. Once the virus leaves the host it dies. In other words the host gives it life.
What provides the energy for viruses?
The host
