A fomite is a non-moving object responsible for the indirect transmission of disease.
Fomites are inanimate objects involved in the indirect contact transmission of pathogens. These objects include a whole range of items mostly found in indoor environments.
When pathogens such as viruses and bacteria come in contact with these objects through various human and animal activities such as sneezing or coughing, use of toilets etc; these pathogens remain active on these objects and can then cause disease when others come in contact with these objects.
<h3>How do fomites transmit infectious agents?</h3>
Some diseases are more likely to be transmitted by pathogens than others. However, several factors can influence whether bacteria on carriers are successfully transferred to humans.
- type of bacteria or virus on the carrier
- number of bacteria or viruses leading to infection
- room temperature
- room humidity
- carrier porosity.
Sneezing and coughing can transfer bacteria to surfaces through droplets released by the sneeze or cough itself, or by bacteria from a sneeze or cough getting on the hands and coming into contact with a bacterial carrier.

Answer: Native species can be the hardest to explain. Simply put, natives are species that are from a particular place without human intervention–humans didn’t put them there directly or indirectly. Digging into that a bit means that “native” can vary a lot based on what scale one is considering, and whether or not there are records of pre-settlement organisms (think fossils). As with anything, there are lots of other names for native, like “indigenous.” Non-native species spread by natural process or human activities. ... When an exotic species becomes harmful to the ecosystem, it is called an invasive species. The main difference between exotic and invasive species is that exotic species is harmless to the ecosystem whereas invasive species is harmful to the ecosystem.
Explanation:
Answer:
Geological, chemical, paleontological.
Explanation:
Geological evidence for ice ages comes in various forms, including rock scouring and scratching, glacial moraines, drumlins, valley cutting, and the deposition of till or tillites and glacial erratics.
Successive glaciations tend to distort and erase the geological evidence, making it difficult to interpret.
It took some time for the current theory to be worked out.
There have been at least four major ice ages in the Earth's past.
Paleontological by their bones, remains
