Help plz i will mark the brainlest plz anyone help A scientific hypothesis should be specific and demonstrate the relationship between the independent variable and the dependent variable. Which of the following is the best hypothesis written in the correct format? Question 5 options: Cars on different surfaces skid at different speeds. If surface type affects friction, then cars on concrete will skid slower than cars on ice. If cars on concrete skid slower on ice, then concrete is the best surface I think a car on the concrete will skid the slowest.

If surface type affects friction, then cars on concrete will skid slower than cars on ice.

Explanation:

This answer choice addresses both the independent and dependent variables. Surface type is the Independent variable, and the dependent variable is the speed the car skids.

hope this helped!

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.

the wetland preservation movement began in the u.s. in earnest with the clean water act (cwa) of 1972. although not specifically written to protect wetlands, the cwa is comprised of a series of regulations designed to prevent pollutants from contaminating u.s. waters.
