Explanation:
It occurs when the carboxylic group of one molecule reacts with the amino group of the other molecule, linking the two molecules and releasing a water molecule.
Chronic tissue hypoxia in children can be observed in patients who have history of tetralogy of Fallot, which is a condition of congenital heart disease that has abnormalities occurring simultaneously. Skin color changes, tachycardia, rapid breathing, wheezing, confusion, sweating, and coughing are also seen commonly in chronic hypoxia patients and this should be a hint in assessing the condition of the patient.
The answer is Osteon. Osteons<span> are several millimeters long and about 0.2 millimeter in diameter; they tend to run parallel to the long axis of a bone. The </span>osteon<span>units of bone are made up of Haversian canals (HC) and Volkmann canals (VC), which run perpendicular to the long axes of </span>osteons<span> and connect adjacent Haversian canals.</span>
Answer:
A genetic sequence, the TATA box, is a transcriptions start site and initiates transcription through the formation of RNA polymerase. Negative regulation may inhibit the initiation of transcription and/or repress gene expression.
Explanation:
proteins called transcription factors bind to the TATA box, this triggers RNA polymerase to start synthesizing RNA to DNA
