You are growing plants hydroponically (rooted in an aqueous solution rather than soil). the solution for the control group of plants contains normal levels of salts and nutrients, while the solution for the treatment group has a high concentration of large molecular weight solutes that are excluded by roots. you find that the plants in the treatment group are on average smaller than those in the control group, but there is no significant difference between the groups in the amount of co2 being fixed by the average plant. what differences at the cellular level between groups would you expect to make an important contribution to the difference in size of the shoots? the girth of cells in the elongation and mature zones would be larger in the control group. the length of cells in the elongation and mature zones would be larger in the control group. the total number of cells in the treatment group shoots wo

because it does not have the potential to be entirely used up

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
