What aquatic species is the least susceptible to acid rain? (Refer to the chart in the lesson to answer this question.) a bass
b Baetis mayflies
c Bullfrogs
d Rainbow Trout

The correct answer is

a gamma ray

In fact, only electromagnetic waves can move through empty space, and gamma rays are an example of electromagnetic waves. In fact, gamma rays are the electromagnetic waves with greatest energy, since they are the electromagnetic waves with highest frequency (and the energy of an electromagnetic wave is proportional to the frequency, following the relationship

where h is the Planck's constant and f the frequency).

Therefore, gamma rays can move through vacuum and carry a lot of energy.
