Viruses (biological)
A virus is a small infectious agent that can replicate only inside the living cells of organisms. Viruses display a wide diversity of shapes and sizes, called morphologies. Generally viruses are much smaller than bacteria. Most viruses that have been studied have a diameter between 10 and 300 nanometres.

Account for the inability of aerobes to grow in the absence of O 2?
their enzyme system necessitates use of O2 as the final hydrogen (electron) acceptor in the complete oxidative degradation of high-energy molecules such as glucose.
Stress will not directly cause the coronavirus, but excessive stress does cause the body's immune system to weaken. A weakened immune system does not have the ability to fight off viruses like a strong one would.
I believe it has been in the US since at least December, people who had the flu shots and yet developed flu like symptoms that lasted up to 14 days yet tested negative for the flu, symptoms included cough, headache, body ache, lack of apatite and just wanting to sleep, it was brushed off as a unknown virus
Can you get the flu shot if you are taking a narcotic?
As long as the reason you take the narcotic would, by itself, not cause a problem with getting a flu shot. If in doubt, always contact your doctor's office and ask a nurse or the doctor there who knows your medical history what you should do. Or before you get the shot, tell the nurse giving it about your condition and they can decide if it is a good thing to get it then.
What must HIV surface protein do to enter a host cell?
The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell.
If a virus is a pathogen this means?
A pathogen is a microorganism that causes disease such as bacterium and viruses. All viruses are pathogens, which means they all cause disease
it causes disease But a pathogen is a living organism and a viru
s is not so its really argumentive.
Can you get the flu from a person who has allergies?
If the person who has allergies also has the flu, then yes.
You cannot get the flu from someone just because they have allergies, if that's what you're asking.
What enzyme is needed to turn a RNA virus into a DNA virus?
The enzyme needed to convert RNA into DNA in a process called reverse transcription is called reverse transcriptase. This enzyme is unique to retroviruses, such as HIV, which use it to convert their RNA genome into DNA once they infect a host cell.
Viruses are not an organism at all. They are not alive. They are nonliving. They are like cockle burrs that "grab" hold of your clothing or a dog’s coat. They are hijackers. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts. These particles can assemble into more viruses and then they break out of the cell (killing it) and begin the process again. They cannot make more viruses on their own.
What is the key regulations that controls lytic and lysogenic?
Lytic and lysogenic cycles are primarily regulated by the genetic and environmental factors that influence viral replication. In the lytic cycle, viruses express early genes that promote replication and cell lysis, while in the lysogenic cycle, viral DNA integrates into the host genome and is regulated by repressor proteins that prevent lytic gene expression. The decision between these cycles is often influenced by environmental stressors, which can trigger the transition from lysogenic to lytic, a process known as induction. Additionally, the presence of specific host factors and the state of the host cell can also play crucial roles in determining the cycle a virus will enter.
They will just bleed out since they can not clot their blood.
Does Russia have confirmed cases of the Coronavirus?
Actually, yes. Although not many. As of March 25, 2020 (Today, also the day I'm writing this answer), Russia has 658 total cases of the Coronavirus, 2 deaths and 29 people who recovered from it. If you are reading this in the future, feel free to type "Russia COVID-19 cases" into any search engine and find the correct answer.
