A _____ is a non-moving object responsible for the indirect transmission of disease.
ivanzaharov [21]

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.

Bats, butterflies, and most birds share flight as a trait. However, none of these organisms share the same Class, this trait is
CaHeK987 [17]

Answer:

The correct answer is convergent evolution.

Explanation:

The wings of bats, butterflies, and most birds are the example of analogous structure. Analogous structures are the structures which are similar in appearance and function but have separate evolutionary origin.

They are similar superficially because they experienced a natural selection that evolved them to have that shape which helps them to fly. Analogous structures are produced due to convergent evolution.  

Convergent evolution describes the presence of the same trait in unrelated species. Therefore the correct answer is convergent evolution.
