What are hormones that make cells resistant to viruses?
interferons
What is the difference between cells and viruses?
Virus: is a strand of hereditary material surrounded by a protein coating that can infect and multiply in a host cell. Host Cell: a living cell invaded by or capable of being invaded by an infectious agent.
What does a virus ultimately do to the host cell?
After leaving the host cell, the virus goes to insert its DNA into even more cells. After a while, there are thousands of cells with the DNA of the virus. With that DNA, the cells make more viruses. There are two cycles for this; Lytic and Lysogenic.
Do viruses replicate in cells of organisms?
Yes. This is the reason that viruses infect cells. The virus injects its genetic material, either DNA or RNA, which then takes over the cell's activities and turns the cell into a virus factory, causing the cell to make new virus parts and assemble them. Eventually the cell ruptures and the new viruses are free to infect other cells.
Is there homeostasis in a virus?
No viruses do not have homeostasis. They have no cellular activities because they are not made of cells. Viruses do not respond or adapt to the environment. Any changes in the viruses are brought about by the host cells that make the new copies of the virus. When science says that viruses evolve, it is really the host cell that makes the changes in the virus. So the virus type accumulates these changes, but it doesn't make the changes itself.
What are hormones that make cells resistant to viruses?
interferons
Why do viruses make us sick?
A virus will make us sick because it disrupts the function of the cells or actually kills cells. Viruses uses healthy cells in order to replicate.
How do cytokines help in biotechnology?
Cytokines, also known as immune factors, are protein produced naturally by the cells and organs of the human immune system. They act on other immune system cells modulating the body's response to disease and infection. Cytokines can also regulate the growth of new blood cells in the bone marrow.Cytokines play a crucial role in the immune system response to all kinds of disease. They interact with organs and cells, alone and in combination with each other. The diverse role that cytokines serve in the immune system make them an ideal target for intervening or bolstering immune responses. Using recombinant DNA technology cytokines can be created in a laboratory. They have many treatment applications including cancer, multiple sclerosis, anaemia, and rheumatoid arthritis.
What are viruses hidden in?
Cells, they reproduce by invading a cell and using its functions to make more viruses, eventually killing a cell. That's why viruses are bad, and that where they "hide".
What do the T-cells do?
If im correct, helper t-cells activate: b-cells that mark viruses and make them stick together, killer t-cells --which attack macrophages and infected cells, and memory b-cells, which remember how to stop viruses, this i believe is called active immunity
What cells do helper T-cells activate?
If im correct, helper t-cells activate: b-cells that mark viruses and make them stick together, killer t-cells --which attack macrophages and infected cells, and memory b-cells, which remember how to stop viruses, this i believe is called active immunity
Are viruses a solid liquid or gas?
A virus is a solid but very tiny particle. It high jacks another cells to make more viruses.

Do viruses break into bodies cells to reproduce?
Yes, that's basically what they do: they take over the cell's own ability to reproduce itself but then not to make more of that cell but to make more viruses.
What is the difference between cells and viruses?
Virus: is a strand of hereditary material surrounded by a protein coating that can infect and multiply in a host cell. Host Cell: a living cell invaded by or capable of being invaded by an infectious agent.
What is the superbug?
Super bugs are a class of viruses and bacteria that are resistant or immune to antibiotics. They are a growing concern because they are appearing faster than we can make drugs that can treat them.
How you make a sentence with the word expels?
The body expels viruses by itself, using white blood cells.
