The Water Circuit of the Plants - Do Plants have Hearts ?

There is a correspondence between the circulation of blood in all higher animals and the circulation of sap in all higher plants-up to heights h of < ∼ 140 m-through the xylem and phloem vessels. Plants suck in water from the soil, osmotically through the roothair zone, and subsequently lift it osmotically again, and by capillary suction (via their buds, leaves, and fruits) into their crowns. I...

Professional musicians and non-musicians who were matched on age, education, vocabulary, and general health were compared on a near-transfer task involving auditory processing and on far-transfer tasks that measured spat...
