Answer:
B. the role of creativity in scientific discovery
Explanation:
Watson and Crick's ball-and-stick model of DNA demonstrates the importance of creativity in science. Creativity involves having a questioning mind that is always searching for answers and which employs logical reasoning to arrive at these answers. After Rosalind Franklin obtained an X-ray diffraction of DNA, Scientists Watson and Crick expanded on this knowledge by creatively organizing ball and sticks in a manner that represenseted the structure of the DNA.
This simple creative act led to more discoveries about the DNA including the facts that their was a pairing wherein Adenine paired with Thymine and Cytosine paired with Guanine. They also found that the DNA structure could be unzipped and that copying was also possible. They used the simple things around them to arrive at this conclusion. This is an example of the importance of creativity in science.
mass * temp change * specific heat
make sure the specific heat value is in Joules
Answer:
A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium.
Explanation:
While waves can move over long distances, the movement of the medium of transmission—the material—is limited. Therefore, the oscillating material does not move far from its initial equilibrium position.

Answer:
The density.
Explanation:
The density is an intensive property of fluids, defined as mass divided by volume.
This property is directly related to the intermolecular forces that are present in the substance: the stronger the intermolecular forces, the higher the density will be, and viceversa. Therefore, organic fluids usually have lower densities than water, because <u>the intermolecular forces in organic fluids are not as strong as in the intermolecular forcer in water</u> (water has very stable hydrogen bonds, whereas organic fluids have van der Waals, weaker than hydrogen bonds).
The liquid that has the lower density will be the the liquid that is on the top layer. In this case, the organic compound tert-butyl methyl ether will be on top of water.
