As trees get larger and the number of leaves increases, transpiration rates rise and demand for water increases. how do mature plant stems meet this added demand for water?

cells of secondary phloem adjacent to the vascular cambium differentiate into xylem cells.

vascular cambium continues to divide, and cells of its inner surface differentiate to form additional secondary xylem cells.

cells of the xylem continue to divide and produce more cells that transport water.

cells present in the pith closest to the xylem differentiate into xylem cells.

Elements and compounds are pure substances that cannot be broken down physically into a simpler substance. a physical change doesn’t break the bonds between atoms of a substance or form new ones. compounds can be broken down by a chemical change. a chemical change breaks chemical bonds and/or forms new ones between atoms of a substance. what simple substance would a compound break into? the basic elements that make it up! for example, if you passed a very strong electric current through water you’d break the chemical bonds in water and be left with oxygen and hydrogen. which of the following is an example of a chemical change? a separating water into different glasses b breaking frozen ice cubes with a hammer c running an electric current through water d boiling water to evaporate it on a stove

For this question look at the hydropic diagram water that is heated by the sun evaporates. select the number that represents it.

Which example would the nurse consider to be a part of systems thinking theory?
