1) if you were lost at sea and you drank salty seawater, what would you expect to happen to the cells in your body? (shrink, swell, or stay same size )why do you think that?
2) a large-mouth bass is taken from a fresh water lake and transplanted into the river. if the conditions for survival are optimal, would you expect the cells in the fish to shrink, swell, or stay same size why do you think that?
3) if a sea star egg is taken from the ocean and put into elk lake would you expect the egg to shrink ,swell, or stay same size why do you think that?

the correct answer: the index of refraction of the second medium is lower i tried this persons answer and it was wrong this person is lying

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.

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.
