Charge must come in specific-sized bundles. Only integer multiples of this smallest amount of charge can be found in Nature.
 
  What will be an ideal response?

Question 2

What is the temperature difference across a window if the conductive heat flow rate across it is 20 J/s? The window is 4.5 m2 in area that has an R-value of 2.5 m2 C/W.

Answer to Question 1

This statement is correct. The smallest size of charge found in Nature by
experiment (this experiment is known as the Millikan oil drop experiment) is 1.6 x 10-19 C.

Answer to Question 2

We find the rate of heat transfer from
rate of heat transfer = A DT/R = 4.5 m2 x DT/(2.5 m2 C/W).
This allows us to find DT. We have
DT = R x (rate of heat transfer)/A = (2.5 m2 C/W) x (20 J/s)/(4.5 m2) = 11.1 C.

Fatal fungal infections may be able to resist newer antifungal drugs. Globally, fungal infections are often fatal due to the lack of access to multiple antifungals, which may be required to be utilized in combination. Single antifungals may not be enough to stop a fungal infection from causing the death of a patient.
