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?

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.

d. planting trees

the trees take in carbon to make oxygen.

she will be charged $6

step-by-step explanation:

48 dollars divided by 200 beads equals .24 dollars a bead

.24 multiplied by 25 more beads equals 6 dollars as the total cost
