In active transport, molecules must cross the concentration gradient. in which direction would the molecules be moving?
a. down the concentration gradient
b. up the concentration gradient
c. no net movement in the concentration gradient
d. stays in the same concentration gradient

1. the energy lost to disorder metabolism     -entropy

2. related to or possessing motion potential     -kinetic

3. all of the chemical reactions in an organism required for maintenance of the processes of life entropy     -metabolism

4. possible; ability to go into action or perform work kinetic     -potential

5. the study of energy and its transformations thermodynamics     -thermodynamics

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.

all these collisions do one thing, and that thing is explained in the last option. when dusst, rocks and ice collide, they harden and form giant layers of rocks or hard ice.

d)   to harden materials to form different parts of earth’s layers

hope it ,
