this map shows the amount of groundwater (gw) in parts of pakistan. farmers in pakistan once relied on rivers and canals for their water supply, but as cities expanded and
populations grew, more farmers used groundwater for their crops. when this map was made, there were no laws restricting how many wells could be built in pakistan to remove
groundwater.
what would be the best solution to pakistan conserve their water supply?
a.
increase the number of groundwater wells in all three regions.
b.
build more wells in region 3, and restrict building in all other regions.
c.
pass laws restricting well building in region 1, but increase wells in regions 2 and 3.

i think that d. wind is the answer.   i missed the question when i answered a. currents.

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'

idk what happened..you tell
