bacteria use pilli as the sites of attachment.. these are hollow,non helical tube like structures.. but are smaller than flagella.. sex pilli are sites of attachment for the process of conjugation..

What is a host cell for a virus?
Host cells of viruses include human and other animals, and plants and fungi. Also bacteria and protozoa and algae are host cells of viruses.
What is bacterial mutation?
this is a process similar to transformation.the only difference is that it does not use a becteria as a host cell.
Does a virus use sexual reproduction?
Viruses cannot reproduce themselves alone. They inject their DNA into living cells of a host organism. The virus cells use the host cells to develop themselves and leave the cell when ready. Viruses are not living, so they are dependent on a living organism for reproduction.
What does a virus require for replication?
Viruses need a living host for reproduction. They, themselves, are not alive, so they must have a living host to provide the material to use for building duplicates, as well as for the energy to use in the production.
What type of chemical reaction occurs when meat rots?
It begins when decomposers such as bacteria begin digesting the meat. Parts of the meat are broken down into nutrients that the bacteria can use, which can alter the initial chemical composure of the host body. As far as specifics, I do not know.
What part of lion is used to get their food?
Lions use their claws to attach themselves to their prey and use their jaws to suffocate them.
What are the main differences between a virus and a bacteria which enable scientists to classify them?
Bacteria are single-celled organisms that can replicate themselves. By this, I mean that they have all the genetic material to replicate (DNA & RNA). Viruses, in contrast, contain a piece of genetic material that is encapsulated by a protein coat known as a capsid. Because viruses only have a portion of genetic material, they have to infect a host organism and inject its material into the host and use the host to do the work for the virus. Since bacteria can "live" on its own and viruses cannot, bacterial infections can be treated with medications while viral cannot. In comparison of size, viruses are about 100 times smaller than bacteria. About of 90% of known bacteria live in a symbiotic relationship with humans. This means that the presence of bacteria is beneficial to both the bacteria and humans. In comparison, most viruses feed of the host to produce more viruses... therefore having no benefit to the host.
Lampreys are parasites that attach themselves to other fishes by suckerlike mouths and they use their to scrape away the flesh?

What do spopnges use for movement?
Sponges use currents or contract their bodies to provide movement. Most will attach themselves to the bottom and stay there for the rest of their lives.
Can virus obtain and use energy?
No. Viruses do not have a metabolism. They rely on a host to do that.This is why they are not considered "living" creatures, but bacteria are.
Why can you not kill flu with antibiotics?
Antibiotics are only for killing bacteria, they do not work on viruses which are the cause of the flu. Bacteria are living organisms and so poisons and chemicals can actually kill them. But flu viruses are non-living organisms so they can not be killed, they can only be inactivated by damage or physical blocking by antibodies (made by our immune systems) of the shapes of the structures viruses use to attach to a host's cells. Viruses need a host's cells to use to reproduce, if they can not attach to the cells, they will be inactivated. Antibiotics are not capable of inactivating them.
How does a bacteria cell move itself?
There's not THE ONE way how bacteria move. some are enabled to diapedeses, others have flagella, others use the flow of their environment to get transported, others use parts of their host cells moving machinery,...
Is the pirate bay safe to use with a mac?
yes it is because mac cant 'welcome' any viruses, they get whiped out as they try to attach themselves.
What is bacterial mutation?
this is a process similar to transformation.the only difference is that it does not use a becteria as a host cell.
What website did Owlient use to make Howrse?
Owlient coded Howrse themselves, and most likely purchased their own servers to host their domain. They did not use a free host (such as Webs, Weebly, or uCoz) to create their website.
Does bacteria need a host to carry on life processes?
Intestinal gut bacteria use humans as a host while also supplying them with valuable nutrients in return. By feasting on digested foods across the tract these bacteria can release life essential nutrients such as Vitamins B and K. By definition it is a symbiotic relationship between humans and our gut flora.
