Active site
A reactant
binds to an enzyme in a region known as the active site during a reaction. The active site is the
most important part of the enzyme because it is where the chemical reaction
happens. It usually contains three to four amino acids and a binding site that
binds the substrate and prepares it for catalysis.
There is no video but I found an image that has the steps to be put in the correct order. Attached is the image.
In taking the blood pressure of the patient, it is best to put the patient on seated position with his or her arms at heart level. The cuff should be placed at least 2 fingerbreadths above the cubital fossa. In using the stethoscope, it is better to use the bell of the stethoscope rather than the diaphragm as we need to hear low pitched sounds.
The first step after all the preliminary steps are done is to wrap the cuff around the arm just above the elbow. Then place the stethoscope over the brachial artery which is in the medial side of the cubital fossa. Next is to squeeze the bulb and inflate the cuff above the systolic pressure. Next is to slowly release the pressure valve. Record the number when the first Korotkoff sound appears (systolic blood pressure). Then record the number when the last Korotkoff sound disappears (diastolic blood pressure). Lastly, is to deflate the cuff.
Answer:
<u>40 seconds</u>
Explanation:
This is the answer for plato users.
Answer:
They showed how organic molecules could be made from Earth's early atmosphere.
Explanation:
Miller-Urey experiments were based on the ides of a-bio-genesis. It means the production of life through the non biological factors. In this experiment it shows that life can be produced through chemicals and molecules that were found in the early form of earth and is composition.
It kind of gives off to the evolution theory and the amino acids which are the building blocks of life and were given rise to during the simulation.
