The diagram provided shows the carbon and nitrogen flow through a man-made mussel bed in the ocean. What evidence would support the law of conservation of mass for this ecosystem?

A. A The amount of carbon and nitrogen removed during harvest equals the amount seeded as biomass.
B. B Carbon and nitrogen enter and leave the ecosystem only through man-made processes.
C. C The mass of scavengers, decomposers, and feces equals the mass absorbed from phytoplankton and detritus.
D. D The total amount of carbon and nitrogen entering the ecosystem equals the total amount leaving the ecosystem.

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.

e) all of the above

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.'

d. organisms have cells with different shapes and functions.
