Answer:
a virus is an infective agent that typically consists of a nucleic acid molecule in a protein coat, is too small to be seen by light microscopy, and is able to multiply only within the living cells of a host.
a virus is a living thing, and it will die if it doesnt have a host.
Answer:
In an episode of the classic 1950s television comedy The Honeymooners, Brooklyn bus driver Ralph Kramden loudly explains to his wife, Alice, “You know that I know how easy you get the virus.” Half a century ago even regular folks like the Kramdens had some knowledge of viruses—as microscopic bringers of disease. Yet it is almost certain that they did not know exactly what a virus was. They were, and are, not alone.

Cross-connections, which are physical links between clean and potential sources of contamination, present several risks primarily concerning health and safety. These risks include the transmission of diseases through contaminated water or medical equipment and electrical hazards in case of improper wirings.
A cross-connection exists when there is a physical link between a clean water source and a potential source of contamination. The risks associated with cross-connections primarily relate to the health hazards of consuming contaminated water, such as disease transmission, and possibly, complications ranging from gastrointestinal issues to fatal illnesses.
For example, in health care settings, a cross-connection might involve pathogens potentially introduced into the bloodstream via contaminated catheters, dental procedures, or wounds. This connection could lead to increased risk of diseases like Hepatitis B. In more severe scenarios, cross-contamination could lead to outbreaks like the one seen in the Flint, Michigan, water crisis, where pollution in the city's water system led to widespread health issues.
Moreover, cross-connections in electrical systems also present risks, like thermal hazards where excessive electric current causes undesired heating effects or shock hazards, potentially lethal electric currents passing through a person.

3. Explain the roles and other compounds in the body.
Together, the many cell components are able to keep the cell alive and functioning.
One cell cannot help us move, but tissues like muscles may because cells work together to create them. For example, one cell cannot help us move, but tissues like a muscle can.
Organs are created when tissues come together and do all the tasks required to keep a person alive.
The cells of one kind of tissue cooperate with one another since the tissues are specialized for various purposes. For instance, all the muscle cells in your calf muscles cooperate to support your gait or speed up your pace.
Therefore, an organ system is a set of organs that collaborate to carry out a certain function.
