What is a medulla? what do forensic scientists use this for?

medulla is a set of cells that runs through a hair.

Explanation:

The medulla is typically different depending on the species that the hair came from, which makes it one way to distinguish between animal and human hair. Forensic scientists may also look at the shape and color of pigment in the hair and whether or not the hair has been dyed or bleached. As hair grows about one centimeter a month, it may be possible to determine how long it has been since the hair has been dyed or bleached by looking at the natural end of the hair. Forensic scientists also examine hair for any abnormalities or deficiencies that may help them determine whom the hair came from.

answer; i believe that the correct answer is; ///bodies of water store heat during the day and release it at night;

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
