Which of the statements represent the laws of thermodynamics? select all that apply. a) matter cycles in the biosphere, but energy flows. b) the energy available to do work decreases as energy is transformed from one form to another. c)enzymes lower the activation energy requirement of reactions. d) the amount of energy in the universe is constant. e)all cells arise from pre-existing cells.

b) The energy available to do work decreases as energy is transformed from one form to another.

Explanation:

Option b) agrees with the second law of thermodynamics which states that energy transferred from one body to another will increase the entropy of the universe and reduce the quantity of usable energy available to do work.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
