Electricity could be discovered using batteries based on zinc or lead, but without copper wiring it would remain little more than a scientific curiosity. Electric motors and generators require large amount of wiring, so they are impossible to build on large scale in this world

A verdict of not guilty constitutes an acquittal. In other words, to find a defendant not guilty is to acquit. At trial, an acquittal occurs when the jury (or the judge if it's a judge trial) determines that the prosecution hasn't proved the defendant guilty beyond a reasonable doubt
Answer:
The correct answer is "Renin".
Explanation:
The secretion of the enzyme renin by the kidney is one mechanism used by the kidneys for blood pressure regulation. The secretion of renin is the first step leading to angiotensin II production, in what is known as the renin–angiotensin system (RAS). Renin catalyzes the conversion of angiotensinogen to angiotensin I, which is subsequently converted to angiotensin II by the angiotensin-converting enzyme (ACE).
