The chrysanthemum is one of the most popular ornamental plants, whose petal colors are primarily determined by pigment proteins. To develop various petal colors, scientists exposed multiple chrysanthemums to gamma rays (radiation) over a period of time. This resulted in offspring that produced new petal colors compared to previous generations. This is an example of

This is an example of mutation breeding or variation breeding.

Explanation:

Basically, the process of radiating a plant or organism (believe me, this is actually done to animals) is known as mutation breeding. They are hoping to use radiation to induce a mutation that will create different characteristics in offspring.

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.
