Why are viruses hard to cultivate in the laboratory?
Viruses are hard to cultivate in the laboratory because they require living host cells to replicate. This dependency on living cells makes it challenging to maintain viruses outside of a host organism. Additionally, viruses can be very specific about the types of cells they can infect, which further complicates the cultivation process.
Why can't viruses maintain homeostasis?
Viruses lack the cellular machinery necessary to regulate internal conditions, like temperature or pH, which is essential for homeostasis. They rely on host cells to provide the resources needed for replication and survival, making them dependent on the host's environment for maintaining stability.
What are the bacteria and viruses that can make you sick called?
These are called pathogens, which are microorganisms like bacteria and viruses that can cause diseases in humans. Pathogens can infect the body and multiply, leading to illness and symptoms. It's important to maintain good hygiene practices to reduce the risk of exposure to these harmful microorganisms.
How does the skin immune system function to protect the body from external threats and maintain overall health?
The skin immune system acts as a barrier against harmful invaders like bacteria and viruses. It detects and fights off these threats to prevent infections and maintain the body's health.
What kingdom are viruses classified in?
Viruses do not belong to any kingdom. There is an ongoing debate to whether viruses are alive or not. With the facts given, it is up to you to decide if viruses are alive or not. All Living things: -are composed of cells with a complex, organized structure -actively maintain their complex structure and internal environment (homeostasis) -respond to stimuli in their environment -acquire and use materials and energy from their environment and convert them into new forms -reproduce, using the molecular blueprint of DNA -have the capacity to evolve Viruses: -are not made of cells and do not have cells -cannot accomplish the basic tasks of living cells -have no ribosomes to make protein -have no cytoplasm -cannot acquire energy or steal the host's energy -cannot grow or reproduce by themselves or with other viruses -do not respond to stimuli -cannot maintain a stable internal environment -can evolve
What helps mammals that are endotherms?
All mammals are endotherms. They are able to regulate their body temperature and maintain homiostasis. Say the temperature drops to a chilling 30°F, their body will try to keep them warm by staying at a constant temperature.
What can you do to maintain the health of a computer from viruses?
Install a reputable firewall and anti-virus
Why computers are prone to viruses?
Computers run applications and for applications to be useful they need access to important systems that maintain your computer, viruses abuse these permissions and inflict malicious actions on your computer

Is there a difference with viruses and cells?
Yes there is a difference. Viruses are non-living and cells are living This is because Viruses can't reproduce on their own without a host. They don't have a metabolism like cells. They can't maintain homeostasis. They cannot synthesize proteins (they lack the ribosomes to do so) without a host. Without a host viruses can neither generate nor store ATP (adenosine triphosphate). Viruses cannot live unless they have a host.
Why is it important to maintain good health?
Fresh vegetables and fruits everyday low fat foods, then you will get all your nutrients and minerals everyday to maintain good health, otherwise your immune system will run low and you can get colds and viruses.

What are the 3 types viruses?
Computer viruses, Macro Viruses, and Directory Viruses
Why are viruses considered to be nonloving?
Viruses are considered nonliving because they do not exhibit the characteristics of living organisms. They cannot reproduce independently, as they require a host cell to replicate; they lack cellular structure and metabolism, which are essential for life. Additionally, viruses do not respond to stimuli or maintain homeostasis. Their reliance on host cells for survival and reproduction further underscores their status as nonliving entities.
Virology is the study of what?
the study of viruses

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.
