Which of the following is TRUE about most newborns’ hearing and vision? Group of answer choices. a) Their hearing improves during the first four months.
b)Their vision is better than their hearing.
c)Their hearing and vision are about the same.
d)Their hearing is better than their vision.

B

Explanation: At birth, a newborn's eyesight is between 20/200 and 20/400. Their eyes are sensitive to bright light, so they're more likely to open their eyes in low light.

answer: b: experiments that showed that all cells are similar in how they metabolize and in their composition

explanation:

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.
