During electron transport reactions Question 8 options: OH- accumulates on the outside of the membrane while H accumulates on the inside. both OH- and H accumulate on the inside of the membrane. both OH- and H accumulate on the outside of the membrane. OH- accumulates on the inside of the membrane while H accumulates on the outside.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

if you add everything up correctly you should get 69 i got this because 50 plus 19 is it

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.'
