Answer:
Airborne transmission may occur if patient respiratory activity or medical procedures generate respiratory aerosols. These aerosols contain particles that may travel much longer distances and remain airborne longer, but their infective potential is uncertain. Contact, droplet and airborne transmission are each relevant during airway manoeuvres in infected patients, particularly during tracheal intubation.
Explanation:
Each mouse in the study has brown ears.
Animals cause erosion in other ways too. When too many animals live in one place, they tend to eat and trample all the plants. Without the plants to protect the soil, it is much more likely to be eroded by wind and water. Animals cause weathering and erosion on rocky shorelines.
