What do we call living things that share characteristics including processes that make life possible? Question 5 options:

organisms

structure

energy

chemical properties

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.

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.

its temperature is increasing. this causes molecular vibrations to increase.

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added
