The movement of molecules from an area of low concentration to an area of high concentration occurs in (blank) transport. In (blank) transport, molecules move from an area of high concentration to an area of low concentration.

During active transport, molecules move from an area of low concentration to an area of high concentration. Active transport is called "active" because this type of transport requires energy to move molecules. ATP is the most common source of energy for active transport.

hope it helps!

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
