The best answer is b - experiment.
An organized process that is used to gather and analyze observations and test a hypothesis is an experiment.
An experiment is the fourth step in scientific method after observation, question and hypothesis.
An experiment is a test that is carried out under controlled conditions with the purpose of demonstrating a known truth, determine the efficacy of a yet untried thing or to examine the validity of a hypothesis.
A hypothesis is a proposed solution for an occurrence that is still unexplained and which does not fit in current accepted scientific theory.
Rainfall is measured as depth on the surface of the Earth, typically in mm. We know the volume of water in the rain gauge: 1414 cubic centimetres. We know need to know the area of the Earth that this volume fell on. This would be the area of the funnel opening that points up to the sky to catch the rain. We know the diameter is 24 cm. So we need to determine the area of a circle with a diameter of 24 cm. The equation to use is: area = pi * radius^2. Since the radius of a circle is half the diameter, the equation is:
So area is 3.14159 * 12^2
= 452.39 cm^2Volume = depth * areadepth = volume/areadepth = 1414/452.39= 3.13 cm = 31.3 mm
Answer: They teach us about the evidence of evolution
Explanation: According to https://flexbooks.ck12.org, "Structures that have lost their use through evolution are called <u>vestigial structures</u>. They provide evidence for evolution because they suggest that an organism changed from using the structure to not using the structure, or using it for a different purpose."
