What kind of electrochemical cell might likely be used for a task such as electroplating?
a. a plate cell
b. a voltaic cell
c. an electrolytic cell
d. a thermoelectric cell

what kind of electrochemical cell is capable of using energy from an external source in order to cause a non-spontaneous redox reaction to occur?
a. a plate cell
b. a voltaic cell
c. an electrolytic cell
d. a thermoelectric cell

First one is "C" and the second one is also "C". The second one can not be B)a voltaic cell because a voltaic cell is spontaneous and its asking for a non-spontaneous redox reaction which would be an electrolytic cell.

a researcher conducts an experiment on the secretion of a particular hormone in mice. scientists inject mice with a substance that stimulates the production of the hormone. the scientists then test the levels of hormones produced by the mice. the tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. this tool makes measurements, but the measurements aren't .

explanation:

no u

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.
