What else can I help you with?
Would the invasion of a cell by viruses increase decrease or have no effect on the osmolarity of a cell?
The invasion of a cell by viruses increases the cell's osmolarity. This occurs because the viruses act like any other particle. As the number of viruses increases, the number of particles in the cells increases as well. This increased particle number gives the cells an increased osmolarity that could eventually lead to cellular lysis.
Which best describes how common cold spread in the human body?
viruses replicate inside respiratory cells.
Do viruses possess an envelope?
Yes, some viruses possess an envelope, which is a lipid membrane that surrounds the viral capsid. This envelope helps the virus infect host cells by facilitating entry into the cell.
How are viruses injected biologically?
Viruses are injected into host cells primarily through a process called viral entry, which can occur via various mechanisms. For many viruses, this involves binding to specific receptors on the host cell's surface, followed by fusion of the viral envelope with the cell membrane or endocytosis. Once inside, the viral genetic material is released into the host cell, allowing it to hijack the cell's machinery to replicate and produce new viral particles. This process can vary significantly among different types of viruses.
Which is best describes how the common cold spreads in the human body?
"Viruses replicate inside the cell and then burst out of the cell." Hope this helps. Got this from Apex.
Does virus makes the cell it is in produce more viruses?
Yes, viruses use the cell that it has invaded to produce more 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.
Is there a cell membrane in viruses?
Viruses dont have a cell membrane. Instead, they have a protein sheath.
What organelles control entry into and out of cell?
The cell (plasma membrane) is the cell part that controls entry in and out of the cell
What helps the flu or mumps virus enter and leave the host cell?
Viruses like the flu and mumps enter host cells by binding to specific cell surface receptors. They then gain entry into the cell by either fusing with the cell membrane or being taken up by the cell through endocytosis. To exit the host cell, viruses often hijack the cell's machinery to assemble new viral particles which are then released from the cell either by cell lysis or budding.
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 can viruses attach themselves to?
Viruses can attach themselves to host cells, bacteria, fungi, and other viruses for the purpose of infecting and replicating within these organisms. They require a specific receptor on the surface of the target cell to bind and gain entry for their replication process.
