How has biodiversity been affected in areas where green crabs have been introduced? a. additional predators have migrated into the area to feed on the crabs, causing an increase in predator diversity. b. native shellfish populations have dramatically decreased as they are outcompeted by the crabs, causing a decrease in biodiversity. c. the amount of predation on crabs by seabirds has gone up, but biodiversity has not been affected. d. the overall number of crab species has dramatically increased, increasing overall biodiversity.

allowed for the prediction of the properties of missing elements.

carbon atoms, hydrogen, oxygen, and nitrogen.

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.'

i think the answer would be a. after sentence 14! i hope i at least a little
