In the following data table of an experiment carried out at 4°C (39.2 F) over 4 hours

Solution in bag	Solution outside bag	Bag mass change (g):
water	Water	-0.2
20% sucrose	Water	+2.4
, 40% sucrose	Water	+4.3
, 60% sucrose	water	+5.8

Which of the following options represents the dependent variable?

It is important for new scientific findings to be published so that other scientists can review the research and either validate or disprove the findings.

This process of peer-review helps to ensure the accuracy and reliability of scientific research.

Choice A. Scientists will get paid if their findings are published is not correct because while some scientists may receive funding or grants for their research, the primary goal of publishing scientific findings is not for financial gain.

Choice B. Publishing findings will help scientists become more biased is not correct because the goal of publishing scientific findings is to share information and promote transparency, not to promote bias.

Choice D. This prevents other scientists from performing similar tests is not correct because publishing scientific findings allows other scientists to build upon the research and perform further tests to validate or disprove the findings.

Urea is a substance that is excreted by sweat glands in response to the breakdown of proteins and the formation of ammonia.

When proteins are broken down, they produce ammonia, which is a highly toxic compound for the body.

Ammonia is then converted into urea and released out of the body through sweat glands.

Choice B. Sebum is not correct because it is an oily substance secreted by sebaceous glands to lubricate and protect the skin, but it is not related to the breakdown of proteins or the formation of ammonia.

Choice C. Water is not correct because while it is a component of sweat, it is not specifically related to the breakdown of proteins or the formation of ammonia.

Choice D. Lysozymes are not correct because they are enzymes found in tears, saliva and other body fluids that have antibacterial properties, but they are not related to the breakdown of proteins or the formation of ammonia.
