Answer:
Regulatory gene
Explanation:
Transcription is one of the major processes that occurs during gene expression. It is the transfer of the genetic instructions in DNA to mRNA. A strand of mRNA is made using complementary base pairs.
However, there is need for gene expression to be regulated.
Gene regulation refers to the mechanism that acts to induce or repress the expression of a gene. These include structural & chemical changes to the genetic material, binding of proteins to specific DNA elements to regulate transcription. These proteins that influences transcription by binding to specific nucleotide sequences (DNA segments/gene) are referred to as REGULATORY PROTEINS and those involved in regulating transcription of genes are called TRANSCRIPTION FACTORS.
Regulatory proteins controls the rate and manner of gene expression by binding to specific genes, thus, making it easy or hard for RNA polymerase (enzyme that attaches to DNA to synthesize mRNA molecule) to bind to the promoter of that gene.
Transcription factors (regulatory proteins) that promote gene transcription are called ACTIVATORS while those that decrease are called REPRESSORS.
The bronchi are where air passes from the trachea.

They waste in the large intestine pass through the villi, where bacteria and other organisms help to digest nutrients and most oftenly absorb the water content ingested.

weathering takes it away
erosion builds up
Deposition is the geological process in which sediments, soil and rocks are added to a land form or land mass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.
the answer is deposition HOPE THIS HELPS
