Which of the following is the primary way that recycling impacts marine biodiversity? a) by recycling as much plastic as possible, it prevents waste from entering the water. b) fishermen are encouraged to recycle their leftover catch back into the water, thereby increasing populations. c) recycling chemicals encourages higher levels of reproduction in marine organisms. d) purchasing recycled products funds conservation efforts in the ocean.

A). By recycling as much plastic as possible, it prevents waste from entering the water.

Explanation:

Marine biodiversity consists of diversity of flora and fauna which survive in brackish to saline water. The marine life is subjected to be damaged by human activities like disposal of plastics, industrial wastes, and radioactive wastes, into the marine water.

The plastic is a non-biodegradable waste which cannot be degraded or decomposed easily. The plastics will be consumed by the marine animals and this will lead to decline in the marine species.

Therefore, recycling of plastic and preventing the plastic is necessary to prevent the loss of marine biodiversity.

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.'
