Answer:
Hydrogen bonding between water molecules allows water to be <u>cohesive.</u> This property of water allows it to rise from a plant's roots to its highest branches.
Explanation:
Cohesion is that force of attraction between molecules that holds the particles of a substance together with others of the same type. It is said that a liquid has more or less cohesion, depending on whether its molecules are more or less attracted to each other. In water, the cohesion force is high because of the hydrogen bonds that hold the water molecules tightly bound together, forming a compact structure. For example, in plants, it is essential that the water column be kept continuous, so that the tension of the xylem (conductive plant tissue) is transmitted to the root. The water column is held together thanks to the powerful cohesion forces that attract water molecules together.

Answer:
Vainas sinoviales tendinosas
Explanation:
Las vaina tendinosas o vainas sinoviales son mangas de tejido de protección que se encuentran alrededor de las articulaciones o rodean a los tendones. Estas vainas permiten que los tendones se deslicen suavemente, produciendo un líquido (líquido sinovial) que mantiene al tendón lubricado. De este modo, las vainas tienen como función evitar el roce entre el tendón y el hueso. Las vaina tendinosas conforman un revestimiento de dos capas: una interna unida al tendón y una externa de tejido conectivo.
