Parland’s alligator population has been declining in recent years, primarily because of hunting. alligators prey heavily on a species of freshwater fish that is highly valued as food by parlanders, who had hoped that the decline in the alligator population would lead to an increase in the numbers of these fish available for human consumption. yet the population of this fish species has also declined, even though the annual number caught for human consumption has not increased. which of the following, if true, most to explain the decline in the population of the fish species? (a) the decline in the alligator population has meant that fishers can work in some parts of lakes and rivers that were formerly too dangerous.(b) over the last few years, parland’s commercial fishing enterprises have increased the number of fishing boats they use.(c) the main predator of these fish is another species of fish on which alligators also prey.(d) many parlanders who hunt alligators do so because of the high market price of alligator skins, not because of the threat alligators pose to the fish population.(e) in several neighboring countries through which parland’s rivers also flow, alligators are at risk of extinction as a result of extensive hunting.

C) The main predator of these fish is another species of fish on which alligators also prey

Explanation:

The only reasonable explanation as to why the species of fish experiences decline in number despite the fishing being the same, and the number of alligators that preyed on the fish going down, is another species of fish which preyed upon the fishes that are fished, but the alligators were also preying on them. Since the alligators have been mostly removed from the ecosystem, the fish that preyed on the other fishes experienced significant increase in its numbers, and since it feeds upon the other fish, that resulted in constant decline in the population of those fishes. The decline in number will only stop when the carrying capacity is reached for the predatory fish in the ecosystem.

transcription is a process in which information is rewritten. it is something our cells must do, in a more specialized and narrowly defined way. in biology, transcription is the process of copying out the dna sequence of a gene in the similar alphabet of rna. it needs to happen in the nucleus because that's where the dna is. dna is always inside the nucleus unless the cell is dividing.

transcription is the first step in gene expression, which involves copying a gene's dna sequence to make an rna molecule. transcription is performed by rna polymerases. it has three stages: initiation, elongation, and termination. rna molecules must be processed after transcription in eukaryotes.

explanation:

long version:

the protein synthesis consists two processes which are, transcription and translation. transcription takes place in the nucleus. it uses dna as a template to make an rna molecule. rna then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. transcription is the first part of the central dogma of molecular biology: dna → rna. it is the transfer of genetic instructions in dna to messenger rna (mrna). during transcription, a strand of mrna is made that is complementary to a strand of dna.  

these three stages are:

  initiation: in which   is the beginning of transcription.occuring when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

    elongation: in which is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

    termination: in which is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
