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.

The answer that best describes the relative refractory period in the neuron is The resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.
The refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. Thus, because Na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
Answer:1.Yes plants take in carbon dioxide for "air" they need water to keep hydrated sunlight helps it make food.
2.Then the entire process of photosynthesis would crash. If no carbon dioxide the plant would not be able to breath and die, No water and it dies of thrist and no sunlight and the plant shivers and dies.
1. Both processes release energy
2. Both start with the breakdown of a nutrient (glucose)
3. Both yield byproducts
4. Both take place in a cell
5. Both involve pyruvate (pyruvic acid
