Answer:
Anomalous expansion
Explanation:
Anomalous expansion of water is the abnormal way water expands when exposed to low temperature.
At 4 degree Celsius , the density at the top layer is usually at the Maximum which makes the water sinks down and then the water in the lower layer rises up.
When the temperature drops below 4 degree Celsius, the water molecules at the top then freezes leaving the denser molecules at the bottom which doesn’t freeze as a result of their high density.
This way, organisms can survive in the water due to the lower layer not freezing.
This is an experiment where the researcher manipulates one variable, and control/randomizes the rest of the variables. It has a control group, the subjects have been randomly assigned between the groups, and the researcher only tests one effect at a time.
The right answer is D. renal regulation.
Among the many factors that modulate tension (vessels, heart strength, blood volume ...), the kidney plays a vital role because it makes an enzyme called renin that helps increase blood pressure and it regulates the outflow of sodium and water, which contribute to the elevation or diminution of blood pressure in the arteries.
