Which is best describes how the common cold spreads in the human body?
"Viruses replicate inside the cell and then burst out of the cell." Hope this helps. Got this from Apex.
How do viruses affect cells and bacteria?
viruses latch onto a host cell and injects its own DNA into it, this DNA controls the cell and makes it produce more viruses inside the cell, when these are ready the burst out of the host cell killing it, and land on another cell
How does complement kill foreign microbes?
by causing them to burst
How a virus inters your body and 'how it reproduces in your body'?
Viruses are like parasites. They always need host to reproduce and everything. First, they enter through any kind of opening in body, like wound, or mouth. Then the viruses send in their DNA's into uninfected cells using a protein fork. Then the cell is infected, and is forced to produce more viruses. When there are no more resources to produce more viruses in the cell, viruses burst out and the cell dies. This repeats until the infected organism dies.
Why are viruses not considered living things?
Viruses do not have all of the characteristics of living things. They consist of a protein coat which contains either DNA or RNA. They are not made of cells. They have no cellular structures. They do not require nutrients. They do not have metabolism. They do not grow or develop. They do not reproduce on their own. They must high-jack a living cell, inject it's genetic material, which then takes over the host cell which then becomes a virus factory. Eventually the cell becomes so full of replicated viruses that they burst, releasing the viruses so they can go on to attack other cells.A virus is not considered a living thing because it can't live on its own and has to rely on another animals cells to reproduce. A living organism technically has to be able to survive and reproduce on their own without help from other organisms. They don't use their own energy to grow, make food, take food, or produce waste.Viruses are not considered living organisms because they are not composed of cells (the Cellular Theory of Life). Also, viruses cannot replicate independently - they must infect a living cell before their structure and genetic material can be reproduced and multiplied.However, there is a vigorous ongoing debate about whether or not viruses are living - they do have discrete genetic material that is transmitted from "parent" to "offspring", they can react to the environment by changing what proteins they are expressing and some viruses are extremely complex.One of the main reasons viruses are considered non living is because they cannot replicate by themselves. In order to replicate they must find a host cell and inject DNA into the host cell which disrupts the host cell's normal processes by causing it to make copies of the virus instead of carrying out all its normal processes. Once the viruses have been created inside the host cell, the host cell bursts to release the viruses. This is the same reason it is considered parasitic, since it uses the host cell for its benefit and damages or kills the host cell in the process.
Which best describes how common cold spread in the human body?
viruses replicate inside respiratory cells.
Which microbes have to be in cells to reproduce?
Viruses must be inside cells in order to replicate. They don't really reproduce in the biological sense. Their DNA or RNA takes over a living cell and causes it to make and assemble virus parts. Eventually the cell will burst, releasing the newly replicated viruses.
When do viruses reproduce?
viruses can not reproduce without the help of a living cell(host).they remain inert or dead(in-active) when they are in free environment or outside the body(host).when they enter the living cell or in some cases insert their nucleic acid into the host,it takes over the host's biosynthetic machinery and forces it to reproduce essential viral components and after proper assembly the cell burst and viruses leave the cell to infect other cells
Why might an over inflated tire burst at high speeds?
Because the particles all inside are moving causing lots of pressure which also causes it to burst and then the particles are relieved.

Why does a balloon burst when near some hot air?
The answer is fairly simple, while some believe that a balloon bursts when near hot air because the balloon simple melts, it actually has to do with the pressure inside the balloon. When near hot air, the air inside the balloon expands slightly, causing a change in pressure, and causing the balloon to burst.
When attacked by viruses cells die?
Yes, a virus uses a host cell to house and reproduce itself. In the final stage of its parasitic occupation, the virus replicas burst from the host cell, killing the host cell.
Why will a balloon pop if it gets hot?
The plastic skin of the balloon will start to melt, and the air inside will suddenly burst through, causing the balloon to pop.
How does complement kill foreign microbes?
by causing them to burst
How do viruses leave the host cell?
They cause the cell to burst. This is called lysis.
