How do environmental scientists use technology to track the invasive species silver carp? a. they use unmanned aerial systems to photograph carp. b. they use biostimulation to promote carp feeding. c. they use acoustics to identify carp sounds. d. they use gel electrophoresis to detect the presence of carp dna.

Environmental scientists use gel electrophoresis to detect the presence of carp DNA. Option D is correct

Natural resource agencies have established surveillance programs which use environmental DNA  for the early detection of bighead carp Hypophthalmichthys nobilis and silver carp Hypophthalmichthys molitrix before they establish populations within the Great Lakes. This molecular monitoring technique must be highly accurate and precise in order to achieve a confident interpretation as well as efficient, both in detection threshold and cost

the right answer is 6

life 2200 right now look pretty good because on how quickly humans are advansing, life will be a breeze. most by by then would have out lawed disese.most wouldn't have to work anymore beacuse everything would be free. the econamy for most countires would be really good, also by then u.s.a would have probably would have expaned its borders.

so that counculeds my thoghts of how 2200 is you for reading
