Question 4 expressways have fewer collisions than highways because a fewer vehicles use expressways b speeds are slower c they are well designed and maintained

c they are well designed and maintained

Explanation:

The expressway is a fast and uninterrupted traffic lane. It is clear to any driver that there are fewer accidents on expressways than on urban roads, this is explained by the almost complete absence of intersections, the absence of traffic lights, the modern layout of these roads, which are the result of a well-structured project that maintains the expressways. .

However, since we know that speed directly influences the severity of the accident and knowing that we need to speed up the expressways even for safety reasons, since we have to keep up with the other vehicles, all we have to do is know some basic safety rules to navigate these roads without exposing our lives and assets to risk.

we would need to see the picture to answer it

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.
