how do environmental scientists use technology to track gray wolves?
a. they use gel electrophoresis to analyze wolf dna.
b. they use acoustics to identify wolves by their howls.
c. they use unmanned aerial systems to photograph wolves.
d. they use biostimulation to promote wolf movement.

• Gel electrophoresis (Option A) is used for DNA analysis, not tracking.
• Biostimulation (Option D) promotes biological activity, not tracking.
• Unmanned aerial systems (Option C) for photographing is not the main tracking method.
• Acoustics to identify by howls (Option B) is a valid tracking - related use of technology.
