BSCI 207 Exam 1 Questions and
Answers
Morpho-space - Answer-Distribution of shapes where living systems actually exist

Enthalpy (H) - Answer-Total energy of a system,∆ H is change

Gibb's Free Energy (G) - Answer-Energy available to do work. ∆G = -T (∆S)

Entropy (S) - Answer-Measure of disorder, ∆S is change

First Law of Thermodynamics - Answer-Energy is neither created nor destroyed

Second Law of Thermodynamics - Answer-Determines direction in a reaction

Endergonic - Answer-The reaction has a positive ∆G, it's storing the energy for later use

Endothermic - Answer-We're absorbing energy

Exergonic - Answer-Negative ∆ G, release energy

Exothermic - Answer-Giving off energy

Fick's First Law of Diffusion - Answer-J = -D (∆C / ∆ x)
Flux = - diffusion coefficient (delta concentration gradient / delta distance)

Fick's Second Law / Einstein's Time to Diffuse - Answer-t = x^D
time = distance squared / 2* diffusion coefficient

Stability - Answer-Constancy of information content

Fidelity - Answer-Accuracy of information readout

Entropy - Answer-Degradation of information content

Redundancy - Answer-Number of information copies. Maintains stability & fidelity;
correct reading errors; reconstructs damaged codes

Aperiodic - Answer-Genetic material is an "aperiodic crystal"

RNA - Answer-1. Carry genetic information
2. Catalyze reactions
3. Self-replicate
