Alpha wants to change 0.54 kilometers into a smaller metric unit. she will have to multiply divide add or subtract ?

If she wants to make it into a smaller unit, she will have to A. Multiply.

The correct answer is that she has to multiply.

Explanation:

In case if Alpha desires to modify 0.54 kilometers into a smaller metric unit, then she needs to multiply. Like, if she desires to convert it into hectometers, then she has to multiply it by 10, that is, 0.54 * 10 = 5.4 hectometers. In case, if she wants to convert it into meters, then she has to multiply it by 1000, that is, 0.54 * 1000 = 540 meters. If she wants to convert it into centimeters, then she has to multiply it by 100000 = 0.54 * 100000 = 54000 centimeters.

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.
