The sister chromatids separate and begin moving toward opposite poles of the cell during which phase of mitosis?

Explanation:

Cell cycle is divided into two main phases: i) inter-phase and ii) mitotic phase

Inter-phase is further divided into three phases named as G1, S and G2 phase, it is the phase where DNA replication and other duplication processes occurs, and in this phase cell prepare itself for division.

Mitotic phase, this phase is further divided into four sub-phases named as prophase, metaphase, anaphase and telophase.

In anphase, during cell division, sister chromatids are separated as they are pulled apart by spindle fibers  towards opposite poles.

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.
