Answer:
A reaction that joins the nuclei of two atoms into one
Explanation:
Think of the words "nuclear fusion".
Nuclear = "relating to a nucleus"
Fusion = "joining"
So, nuclear fusion is the joining of two nuclei into one.
A and B are wrong, because chemical reactions involve electrons.
D is wrong, because the splitting of a nucleus is fission.
Answer:
For this receptor, the stimulus begins with an explosion of action potentials.
that would be the correct option.
Explanation:
A tonic receptor is one that is activated when the action potentials were maintained over time and during the signaling of the receptor.
Tone receptors require continuous stimulation over a period of time to trigger a response and deliver it to the central nervous system.
It keeps the nervous system constantly active in the environment that surrounds it.
They are slowly adaptable, an example of these receptors are the merkel and ruffini receptors.
The nurse should obtain the specimen from the catheter.
One of the tests from urinalysis that frequently got contaminated is about infection. The area near the orificium of uretra is near the skin, so there will be microbes around it that can contaminate the sample. The contaminated sample will give a false positive and the result will show the urine are infected.
Taking the specimen from catheter will prevent that contamination, thus giving a better sample.
Answer:
pushing iron out
Explanation:
Excess iron will be push out of the cell to regulate the internal environment of cell, this active transport involve osmosis.
if this type of reaction occur in a plant cell, the plant cell will shrink which may/will leads to death of the plant.
Hope it is helpful
don't mind my grammatical blunders.
Thank you.
