During meiosis, the chromatids of homologous chromosomes have just undergone crossing over. which of the following phases will the cell enter next?

Metaphase of meiosis I

Explanation:

Crossing-over is a process where a segment of one chromosome is exchanged with its homologous pair. It occurs between the non-sister chromatids of homologous chromosomes after they must have paired up side by side. This process of crossing-over occurs in the Prophase stage of meiosis I.

After crossing-over, which may or may not occur, the spindle fibres (developed from the centrosomes) begins to attach to centromeres of each chromosome and move them towards the center of the cell (metaphase plate). The microtubules attaches to chromosomes in a way that homologous chromosomes and not the individual chromosomes are lined up at the Metaphase plate i.e. center. This process of homologous chromosomes aligning at the Metaphase plate occurs in Metaphase of meiosis I.

It is important to note that the random manner in which the chromosomes (homologous) likes up determines which chromosome gets separated into each cell in the next stage (anaphase).

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.
