A virus the immediately takes over a cell's functions is an active virus. An active virus causes the host cell to make new viruses, destroying the host cell.
A group of similar cells performing similar functions is called a tissue. Tissues work together to carry out specific functions in the body.
They are called a tissue.But they should be bonded,perform specific functions and have a similar origin.
viruses are not considered to be living organisms as they lack the cellular structure and cannot carry out cellular functions on their own. They can only replicate by hijacking the machinery of living cells. Therefore, viruses do not challenge the concept that all living things are made of cells.
viruses are used in r-DNA technology in process called bacteriophage.. here viruses are induced with gene of our interest and its multiplied by means of bacteria.. this process is called bacteriophage and here bacteria lyses..
the virus that infects bacteria is bacteriophage
viruses are specific to the cells they infect called host cells
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".
No, viruses do not have a cell membrane. They are considered acellular entities that consist of genetic material (DNA or RNA) encapsulated in a protein coat called a capsid. Viruses require a host cell to replicate and do not have the ability to carry out cellular functions on their own.
Virulent phages or certain types of viruses can destroy host cells immediately upon infection by causing cell lysis. This process involves the virus replicating inside the host cell until it bursts open, releasing new viral particles to infect other cells.
a virus consists only of a single strand of genetic material, while a cell consists of genetic material, a nucleus, and many organelles that all have different functions. because of a viruses lack of materials, scientists debate whether they are actually living things or not.

viruses dont have cells
No, viruses are not made of cells. They are small infectious agents that can only replicate inside the living cells of organisms. Viruses consist of genetic material (DNA or RNA) enclosed in a protein coat called a capsid.
They can not reproduce without a host as reproductive vector. They have no metabolism and do not preform cellular functions. Viruses are genetic material enclosed in a protein capsid.
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
