Question

question 25 of 30
which of these technologies allows scientists to follow the movements of animals after placing electronic collars on them?
a. environmental dna (edna) surveillance
b. geographic information systems (gis)
c. unmanned aerial systems (uas)
d. global positioning systems (gps)

Explanation:

GPS is a technology that uses satellites to determine the precise location of an object. When electronic collars with GPS devices are placed on animals, scientists can track their movements. eDNA surveillance is for detecting DNA in the environment to identify species presence, GIS is for mapping and analyzing spatial data, and UAS are drones mainly for aerial imaging and monitoring from above. GPS is specifically designed for tracking location - based movements of collared animals.

Answer:

D. Global positioning systems (GPS)
