Answer:The anesthetic may cause a severe headache, which is treatable."
Explanation:
Spinal anesthesia is a type of anesthesia which is administered locally using a fine needle between L3 and L4 space or L4 and L5 space in order to avoid injury to the spinal cord. This procedure is usually carried out by a trained health personnel such as:
- a nurse anesthetists and

Answer:
To reduce systematic error.
Explanation:
The researchers would have used random allocation in order to decreases systematic error in the experiment. If we don't apply random allocation to the experiment, there is high chances of systematic error in the experiment and the result is not of high quality. Independent variables is a type of variable whose variation does not depend on another factor while on the other hand, dependent variables is a type of variable whose variation depend on another factor.
Cells have thousands of enzymes to act as biological catalysts.
