Answer:
The red blood cells could burst.
Explanation:
If they are given pure water, the IV fluid will be hypotonic to the blood cells. That means water will end the red blood cells by osmosis, from a high concentration outside to a lower concentration inside.
This will result in the red blood cells becoming swollen and even potential bursting.
Answer:
<u>Keys(enzymes) are specific to certain locks(substrate)</u>
Explanation:
<u>The key and lock model are used to illustrate the enzyme specificity to a substrate</u> function. Enzymes are specific in the reactions they catalyze. An enzyme will only catalyze one specific reaction or a group of closely related reactions.
For enzymes to catalyze a reaction, the substrate(s) must fit in the active site on the surface of the enzyme. This forms an enzyme-substrate complex. The enzymes speed up the formation of the products. The products formed separate from the enzymes so that other substrate molecules can fit into the active sites.
One of the reason is that Crucible tongs are specifically designed to hold the crucible. Using the crucible tongs will minimize the risk of the crucible falling and burning the handler. second reason is that The crucible is extremely hot, so it is inadvisable to handle it with bare hands, latex gloves or clumsy mittens,
