During an investigation, sam observes the number of hummingbirds that come to his large bird feeder at different times of day
he fills the feeder to the top the first day and counts the number of birds at 6 a. m., noon, and 6 p. m. over ten days. what are
the independent and dependent variables in sam's investigation?

the number of birds is the independent variable, and time is the dependent variable.
time is the independent variable, and the number of birds is the dependent variable
the type of bird food is the independent variable, and the number of birds is the dependent variable.
the number of birds is the independent variable, and the type of bird food is the dependent variable.

Time is the independent variable and the number of birds is the dependent variable.

Explanation:

it is the because the number of birds relies on the time of day.

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.
