What benefits are there for organisms that reproduce using mitosis instead of sexual reproduction?

A single cell dividing by mitosis is an example of asexual reproduction--you now have two identical daughter cells (usually thought of as diploid 2n) from one single mother cell.

Meiosis is important to sexual reproduction, because through events like crossing over during prophase 1 (the swapping of genetic material between sister chromatids after a process of pairing called synapsis, the exchange sites are called chiasmus) and independent assortment during metaphase, meiosis creates the variation in genetic material that is potentially advantageous to sexually reproducing organisms and can potentially be acted upon by natural selection to drive the process of evolution.

Meiosis creates haploid gametes (n) that when joined together in fertilization create a genetic combination never having previously existed

Explanation:

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.
