A researcher writes a grant proposal to repeat an experiment that was recently published by another researcher. Which of the following statements best supports the grant proposal?
Repeating the published work will provide independent confirmation of the results.
Repeating published work with changed variables will extend the previous results.
Funding this important research will benefit science in the long term.
Funding this grant proposal will allow this laboratory to continue to study this topic.
The Correct Answer is A
The statement that best supports the grant proposal is a. Repeating the published work will provide independent confirmation of the results. Independent confirmation of results is an important part of the scientific process. By repeating an experiment that was recently published by another researcher, the researcher writing the grant proposal can provide additional evidence to support or refute the original findings.
B. Repeating published work with changed variables will extend the previous results, but this is not the main goal of repeating an experiment.
C. Funding this important research will benefit science in the long term is a general statement that does not specifically support the grant proposal to repeat an experiment.
D. Funding this grant proposal will allow this laboratory to continue to study this topic is also a general statement that does not specifically support the grant proposal to repeat an experiment.

Correct Answer is D
Explanation
The opening of potassium channels allows potassium to leave the neuron. Repolarization of a neuron occurs after an action potential when the neuron's membrane potential returns to its resting state. This is achieved by the opening of potassium channels, which allows potassium ions to flow out of the neuron. This movement of positively charged ions out of the neuron helps to restore the negative membrane potential.
A. The inhibition of sodium and potassium pumps would not allow for repolarization because these pumps are necessary for maintaining the resting membrane potential.
B. The opening of sodium channels would cause depolarization, not repolarization.
C. The closing of both sodium and potassium channels would restrict ion movement, but it would not allow for repolarization.
Correct Answer is B
Explanation
Urea is a waste product that is formed when proteins are broken down in the body. It is excreted by the kidneys in urine, but small amounts can also be excreted by sweat glands in sweat. The other options are not substances that are excreted by sweat glands in response to the breakdown of proteins and the formation of ammonia. Lysozymes are enzymes that break down bacterial cell walls, water is a component of sweat but is not specifically related to protein breakdown, and sebum is an oily substance produced by sebaceous glands to lubricate the skin.
