The cichlid Cynotilapia afra, introduced at West Thumbi Island in Lake Malawi in the 1960s, has split into two genetically distinct populations, located at the north and south ends of the island. How can scientists determine whether these populations are now different species, according to the biological species concept?

Determine whether individuals from one population will interbreed with individuals from the other population when introduced into each other's native habitats

Explanation:

According to the biological species concept, organisms can be considered to be of the same species if they can interbreed successfully together to produce a viable and fertile offspring.

Therefore, to determine whether these populations are now different according to the biological species concept, scientists should introduce both individuals from each population to each other. If they are able to interbreed and produce viable and fertile offspring, it means they are of the same species, but if they are unable, it means they are not of the same species.

i think its the first one

step 1: initiation

initiation is the beginning of transcription. it occurs 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.

step 2: elongation

elongation 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.

step 3: termination

termination 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.
