Answer to Question 1

The extra weight carried by the plane makes a negligible difference in the energy
cost of the trip. The energy use per passenger is therefore just about
total trip energy cost without passengers / number of passengers.

Answer to Question 2

This is correct. A wall-like profile has much more air resistance than a teardrop
shape. Most modern automobiles gave profiles more like the teardrop than the wall.

Though Candida and Aspergillus species are the most common fungal pathogens causing invasive fungal disease in the immunocompromised, infections due to previously uncommon hyaline and dematiaceous filamentous fungi are occurring more often today. Rare fungal infections, once accurately diagnosed, may require surgical debridement, immunotherapy, and newer antifungals used singly or in combination with older antifungals, on a case-by-case basis.
