Answer: .OH, O2-, H2O2
Explanation:
Reactive oxygen species (ROS) are chemically reactive and unstable species containing oxygen. ROS are formed when oxygen is partially reduced, thus they are all radicals with very high reactivity, attacking membrane proteins such as ion channels etc
Examples include peroxides (H2O2), superoxide (O2-), hydroxyl radical (.OH)
The following are the steps the nurse would take to treat the infiltrated site:
1. Stop the infusion and remove the catheter
2. Elevate the extremity
3. Encourage an active range of motion
4. Apply a cold or warm compress depending on the solution infusing
5. Restart the infusion proximal to the location or in another extremity
Now, in order to address hydration requirements of the client, the nurse will have to begin a novel peripheral intravenous in another extremity or to again start the infusion if intravenous access has been created.
In the event of an acid spill, a base can be poured onto the acid to neutralize the acid to allow a safer cleanup.
Answer:
C) are sequence-specific DNA endonucleases
B) degrade foreign DNA that enters a bacterium.
Explanation:
Restriction enzymes are the proteins that cut the DNA at a specific sequence.
<u>Restriction enzymes are also known as restriction endonuclease produced by bacteria that recognizes a specific sequence on DNA and split it by catalyzing the hydrolysis or addition of water molecule. </u>So, Restriction enzymes are sequence-specific DNA endonucleases.
The biological role of restriction enzymes is to restrict the entry of foreign DNA into the bacterium. <u>Restriction enzymes have the ability to restrict the number of bacteriophage strains that affect bacteria.</u>
Hence, the correct options are "C and B"
