Observational research is required to be conducted if someone wants to see whether, when seated next to their closest friends in the cafeteria, students were more likely to spill ketchup on themselves or not.
Moreo about Observational research:
In observational research, people and phenomena are observed in their most natural environments. Instead of using organised environments like study labs or focus groups, this allows researchers to observe how their participants make decisions and respond to circumstances in their everyday lives.
The study of non-experimental circumstances in which behaviour is observed and noted is referred to as observational research. The phrase "what really is going on or what's he doing" could also be used. The variables are neither controlled nor manipulated, hence the study is categorised as non-experimental.

You are being charged a retainer if you are paying for the real time your lawyer spends working on your case.
<h3>What does "lawyer on retainer" mean?</h3>
Retainers are a sort of remuneration arrangement with lawyers that can be used to reserve their services or pay for upcoming work. The standard sort of retainer where a lawyer promises to take on a case or other future concerns for a client is called a general retainer. You are "on-call" for a predetermined amount of hours each week or month if you are on retainer. Regardless of whether he assigns you work, the customer has agreed to pay you for these hours. Service providers typically charge clients a lower hourly cost in exchange for the security that a retainer provides. By default, a retainer is non-refundable and not refunded. It is applied to the total instead. Consider a cleaning deposit for a rented event space or a security deposit for an apartment (separate from the actual fee for the event cost itself). These costs are additional to the overall amount.

Answer: Radioactively-labeled materials
Explanation: nuclear medicine is a medical specialty that uses radioactive tracers to diagnose and treat different diseases. Radioactive tracers are materials that can vary according to the purpose of the method. For most diagnostic, the radioactive tracer is administered by intravenous injection. However it may also be administered by inhalation, by oral ingestion, or by direct injection into an organ.
SPECT scans are primarily used to diagnose and track the progression of heart disease, and the major purpose of PET scans is to detect cancer and monitor its progression, response to treatment, and to detect metastases. This two methods are the most used in nuclear medicine.
