Answer and explanation;Skeletal muscles;The primary function is to attach to and move skeleton Skeletal muscles consist 40% of the body weightThey have fibers with multinucleated cells (embryonic cells fuse) Nuclei pushed off to the side Cells have obvious striations Contractions voluntarySmooth Muscles Cells spindle shaped with one central nucleus. They are grouped into sheets (often perpendicular to each other) They have no striations (no sarcomeres) Their contractions slow, sustained, and resistant to fatigue They do not always require nervous signal.They aid the process of peristalsis They provide multiple functions to organs (ex. change diameter and length of tubular organs) They are usually on organs that need sustained/regular contractionsCardiac muscles They are only located in the heart Their function: reduce size of chambers of the heart (atria/ventricles) They have a system of contractile proteins (ie. sarcomeres) and sarcoplasmic reticulum similar to skeletal muscle They differ in that; they have single cells, intercalated sics, 1-2 nuclei in center, inherent rhythmicity

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.
