Based on the diagram above, which best describes the structure and function of c? a) hollow organ that contains and nourishes the embryo and fetus b) muscular tube into which egg cells are released for fertilization c) narrow passage that transports the egg from the uterus to the vagina d) sexual gland in which egg cells are formed and stored until ovulation

Answer is A.

Explanation:

C is pointing out the uterus, which is described in option A.

A is pointing out the ovary, which is described in option D.

B is pointing out the fallopian tube, which is described in option B.

Option C describes the cervix, which is not labeled in the diagram.

you must remain stopped until the stop signal is retracted and the red lights are turned off. approaching traffic in the opposite roadway of a divided highway shall not be required to stop, even if the school bus has the stop-arm extended and the alternately flashing warning signal lamps on.

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.
