If the student has mass 75 kg, and if the stairs are 3 m high, then 
<span>work = mgh = 75kg * 9.8m/s² * 3m = 2200 J </span>
<span>so I'd say "one one-hundredth." </span>
<span>Except that I think 5000 cal ≈ 20.95 kJ (not J), and that would change my answer to </span>
<span>"ten times or so".

GuDViN [60]

To confirm the above hypothesis, Maria should perform an experiment to prove that xylem is responsible for the transport of coloured water through the plant. This is called the ascent of sap.

A suitable plant having a tender, semitransparent stem should be selected. The root system of the plant should be cut off and the twig has to be placed half-immersed in a coloured solution of water for about one hour. Later, when the plant is observed, parallely running streaks of coloured water can be seen through the semitransparent stem and other parts of the plant indicating that the xylem is involved in the upward movement of water.
