None of the above. Neurotransmitters are chemicals like serotonin, norepinephrine and dopamine inside the brain and thus deal with the specialties of medicine, neurology and psychiatry. Hope that helps!
ANSWER: CASE-CONTROL STUDY
EXPLANATION:
An epidemiology expert will make use of a Case-control Study for proper determination of association or linkage between the oil spill and the disease outbreak (arthritis).
Case-control Study provides an observational experiment between two existing groups (two reservoirs) differing in outcome (affected and not affected), they are highlighted and compared on the basis of a context (disease outbreak; arthritis).
However, the known group is regarded as the control group and it provides a substantial guide to the confirm the validity of other experimental groups in relation to the general context (outbreak of arthritis).
Prior studies have not included trauma and postoperative patients, but it has been demonstrated that therapeutic hypothermia (TH) and targeted temperature management (TTM) improve outcomes in cardiac arrest survivors. We investigated the safety of TH/TTM in surgical and trauma patients. An adult patient who presented with a cardiac or traumatic arrest in the postoperative period and had been treated with either TH or TTM had a Glasgow Coma Scale of 8 when the patient was reviewed in a retrospective cohort study at a single level I trauma center. A patient's neurological recovery is deemed positive if they were released after obeying orders.
32 cardiac arrest patients in all, 14 of whom received TH treatment and 18 of whom received TTM treatment, with target temperatures of 33°C and 36°C, respectively, were included in the study. With 26 (81%) men, the cohort had a mean age of 60 13. There were 14 postoperative patients and 18 trauma patients. Pneumonia (13%), sepsis (6%), bleeding that required transfusion (22%), arrhythmias (6%), and seizures (9%), which are similar to earlier reported series, were among the complications. All survivors had good neurological recovery, and the overall survival rate (n = 13) to discharge was 41%. Patients who had previously been excluded from TH/TTM studies due to traumatic arrest and postoperative cardiac arrest appear to have an acceptable incidence of problems compared to conventional TH/TTM patients.
What is cardiac arrest ?
When the heart unexpectedly and unexpectedly stops pumping, cardiac arrest happens. If this occurs, blood supply to the brain and other important organs is interrupted. Certain arrhythmias that stop the heart from pumping blood result in cardiac arrests. A medical emergency is cardiac arrest.

Answer: B) The number of electron in its valence shell.
Explanation:
Outermost electrons of the atoms which can participate in the chemical bond formation is known as valence electrons.
Atoms either transfer or share its valence electrons during chemical bond formation. Atoms transfer or share electrons to attain octet or in other words stability.
Generally, 8 electrons are required in their outermost shell or valence shell in order to attain stability. This rule is known as octet rule.
For example, general electronic configuration of sodium belonging to group 1 is 1s2 2s2 2p6 3s1.
No. of valence electrons in Na = 1
by loosing 1 electron, its outer shell electronic configuration become = 1s2 2s2 2p6 (Octet)
Hence, sodium and other group 1 elements are very reactive.
Similarly, halogens (ns2 np5) by gaining 1 electron attain octet (ns2 np6). Hence halogens are also very reactive.
Carbon atom belonging to group 14 has 4 valence electrons (ns2 np2) and share all 4 valence electrons to attain octet and hence reactive.
Nobel gases have octet in their outermost shell (ns2 np6), hence they are most nonreactive element.
