The answer is c or a its one of the two
Answer:
a) The enhancer site is a distal control site many nucleotides upstream from the promoter site, and activates the initiation complex of transcription.
Explanation:
Enhancers are the regulatory DNA sequences that are generally located quite away from the coding regions of a gene. These sequences are mostly present upstream of promoter sequences. Enhancers regulate the gene expression by stimulating the formation of an active transcription initiation complex and thereby, increase the rate of RNA synthesis. Enhancers also serve as the binding site for specific regulatory proteins. These proteins bound to the enhancers then activate transcription by interacting with the proteins bound to the promoters.
California is very well known for fires so in this case I'd say go with the answer of "<span>SEROTINOUS CONES" which are special "seeds" to easier put it that only spread with the aid of fire. These cones are spread by fire/wind/gravity as time goes by the trees will grow back as a result.
Another well said answer can be secondary succession. Secondary succession "</span>reduces an already established ecosystem <span>to a smaller population of species" or series of changes that take place after disasters on forests/general like fires.</span>
