b. a transmission electron microscope, because it has high resolution
A scanning electron microscope would be the best choice for a scientist examining the living cells lining the respiratory tract. This is due to its capability of scanning the surface of the whole cells, which is essential to properly observe the tiny hairs on these cells that move dirt and mucus away from the lungs.
To explore living cells lining the respiratory tract, the best instrument would likely be a scanning electron microscope (SEM). While both SEM and transmission electron microscopes provide high-resolution images, a key difference is how they interact with the specimen. The SEM scans the surface of whole cells, making it ideal for observing the tiny hairs, or cilia, on the cells of the respiratory tract. These tiny hairs move in coordinated waves, pushing mucus and trapped particles out of our lungs. This process can be best observed on the whole cell surface, which is why SEM would be preferred.

Answer:
Which process transfers heat from a hot pavement to a person sitting on it? Conduction
Explanation:
There are different mechanisms of heat transfer: Conduction, Convection, Evaporation and Radiation.
Conductionis in this case the right answer because is the process that thasnfers heat by physical contact. The contact in here would be the person and the hot pavement.
When it comes to convection, is the process that transfers heat by the movement of a fluid; evaporation is the process that transfers heat from liquid to gas and radiation is the process that we can see in the microwave which is transfering heat through energy.
