List the five characteristics all organisms on Earth share - correct answer 1. Energy 2. Cells 3. Information (Regulates reactions/Info from the environment) 4. Replication 5. Evolution Explain why the first four are required for life - correct answer -to stay alive and reproduce -cells to grow; membrane regulates the passage of materials b/w exterior and interior spaces -genetic information, responding to the environment, and adjust to maintain homeostasis -population continues ...

What must be constant for a living organism to maintain a homeostatic condition that is far from equilibrium? correct answers constant input of energy What do living systems abide by? correct answers the Laws of Thermodynamics; the spontaneity of biochemical reactions is expressed as ΔGo' in kJ/mol energy charge correct answers a measure of [ATP], [ADP], and [AMP] in the cell and reflects the amount of ATP for metabolic reactions The energy available from redox reactions due to what? ...

What is the most important thing change in Gibbs free energy tells us? What does a negative value mean and what does a positive value mean? - how spontaneous a reaction is negative delta G = spontaneous, energy is released, exergonic positive delta G = non-spontaneous, energy is consumed, endergonic what does enthalpy represent? what does it mean when it's positive vs negative? - delta H is change in enthalpy, which is the heat content of the reacting system. It reflects the number and ...
