1. In 1889, August Weismann, a German biologist, conducted an experiment attempting to produce mice without tails. He cut the tails off adult mice and then allowed them to mate. All offspring had long tails.
He repeated the experiment many times, always with the same results. This experiment helped to
disprove the concept of
a. Inheritance of acquired traits
b. Survival of the fittest
C. Overproduction in a species
d. Struggle for existence

inheritance of acquired traits

Explanation: I took the test and aced it so I hope this helped!!

because the light is a great source of energy for the plants to survive. (i hope this )

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.
