If the amount if algae in the ocean decreases by 50% the population of its consumers, goby fish will? A. Go extinct
B. Decrease to its carrying capacity
C. Increase by 50%
D. Increase to its carrying capacity

B. Decrease to its carrying capacity

Explanation:

Goby fish feed over algae for their survival and growth but if 50% of algae in the ocean decreases then the population of goby fish will decrease to its carrying capacity.

This is so because then the goby fish will be dependent on the left number of algae and maximum population size will depend on the rest 50% of food or algae available.

Hence, the correct answer is "B. Decrease to its carrying capacity".

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.'
