The correct answer is option D, difficulty of redesigning workable ecosystems
Reason -
The area that was redesigned into an ecosystem actually failed to attract the endangered species of clapper rails in California because of the following two reasons –
a) Failed attempt of restoration of Cord grass ( a tree which is a dominant tree in the nesting habitat of clapper rail) . Even if few such trees were there they could not grow to their full height and thus were incapable of providing adequate nesting cover
b) Due to the lack of predatory insect, some herbivore insect in the ecosystem attacked the green grasses thereby making the nesting inadequate.
A laparoscopic cholecystectomy is the removal of gallbladder using a laparoscope which is a narrow tube with a camera and compared to the open cholecystectomy, it only has small incisions instead of a large one. The patient's stomach as part of the procedure will be inflated with carbon dioxide and will be deflated right after the procedure. The nurse should inform the patient then that it is a normal side effect of the carbon dioxide placed into the stomach prior to the start of the procedure and it would just be gone yet patient would just feel a little bit discomfort.
The correct statement is that the concentration of acetylcholine will be inhibited by enzymes and can cause several diseases as follows:
- Alzheimer's disease-related to damage to brain cells,
- memory loss,
- and thinking ability.
How to reduce the symptoms of these diseases is to use drugs that contain cholinesterase inhibitors.
<h2>Further Explanation
</h2>
Acetylcholine is a neurotransmitter that plays an important role in the functioning of the autonomic nervous system. Acetylcholine is one of the most commonly recognized neurotransmitters or nerve stimulating chemicals. These neurotransmitter compounds can be found in the nervous system.
There are several side effects of the acetylcholine drug, which are as follows:
- Can cause a lot of sweat
- Excessive salivation
- Stomach ache
- Headache
- Blood vessel dilation
- Nausea and vomiting
- Diarrhea is a sign of an increase in parasympathetic tone.
