study the image. a graph showing energy taken in and released for two chemical reactions over time. in a reaction with no enzyme, the energy of the reaction rises somewhat to form the activated complex before dropping to form the products. with an enzyme, the peak of the activated complex is significantly lower, though the energy of the products and the reactants remain the same. which answer choice correctly describes the labeled graph? (select all that apply.)

a. the activation energy is much lower with an enzyme present.
b. the activation energy is much higher without an enzyme present.
c. the activation energy is much higher with an enzyme present.
d. the activation energy is much lower without an enzyme present.

a covalent bond, specfically triple bond

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.

passive transport is a movement of biochemicals and other atomic or molecular substances across cell membranes without need of energy input. unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy.

so, according to what that says, i believe it's hypertonic and hypotonic.

good luck!
