The answer is B. circulatory, respiratory, and nervous systems
Although all systems in the body are interrelated and impact one another, the systems that have the most important roles in regulating blood pressure are the ones in B. The circulatory, obviously, is the most important because it consists of the heart, blood vessels, and blood. When the heart pumps blood, it creates pressure on your arteries. These processes are communicated throughout your body using the brain or nervous system. The respiratory system also works closely with the circulatory system because when oxygen enters the blood, it travels to the heart and is pumped to the rest of the body.
Answer:
Because the promoter region is initiation sites for transcription to occur.
Explanation:
Transcription is the first process of gene expression in both eukaryotic and prokaryotic cells. Transcription involves the synthesis of a complementary RNA strand from a DNA template. It is carried out by an enzyme called RNA polymerase which binds to the DNA molecule and adds nucleotides based on the sequence it reads on the DNA.
On the DNA molecule, are sequences of nucleotides which the RNA polymerase recognizes and binds to in order for the transcriptional process to start. These sequences are called PROMOTER regions. They are located upstream i.e. after initiation site, of the DNA. Without these promoter region, RNA polymerase cannot bind to the DNA molecule and hence transcription cannot occur.
The option that would most likely happen to a unicellular organism if it was exposed to a hypotonic solution for an extended period of time is that it would swell and then burst.
Over the next decade the Ogallala aquifer will be completely depleted and will affect portions of the central and southern High Plains Aquifer (HPA). The Ogallala Aquifer is one of the largest bodies of water in the United States and is is generally used by farmers for irrigation of crops. As the continuous depletion of the aquifer occurs, it may become problematic for agricultural industries to sustain their farming.
