Temperature is considered an biotic limiting factor. The correct answer is A.
Cheese because it is made of mold and mold is good for you, sometimes. Hope this helped!
Answer: Promoter
Explanation:
Transcription is the first step in gene expression which consists of copying the DNA sequence of a gene to produce a RNA molecule. There are enzymes called <u>RNA polymerases which perform this process of transcription</u>. These enzymes bind nucleotides (the monomers which are part of the nucleic acids) to create a RNA strand using a DNA strand as a mold.
A promoter is a region of DNA that controls the initiation of transcription of a given portion of DNA to RNA. Therefore they promote the transcription of a gene. <u>The promoter region is composed of a specific sequence of DNA located just where the starting point of the DNA transcription is</u> and contains the information needed to activate or deactivate the gene it regulates. <u>The promoter has a binding site for the RNA polymerase enzyme </u>in charge of mRNA synthesis and when it recognizes this site, transcription begins.
The burning of fossil fuels can cause smog and acid rain.
Answer:
Just by the way they look.
Explanation:
They have the same kind of bone structure, and the only real difference would be in size/shape of the bones, and the color of the fur.
