If evolution is going to occur as a result of natural selection, what must be true about the trait that is being studied? *

All forms of the trait have the same impact on survival.
The trait is passed on genetically to the next generation.
The trait is resistant to mutations.
The trait is the same for all organisms.

How is an environment able to support different varieties of organisms?

Are salt and soap nutrients or toxins for yeast? explain.

An enzymatic hydrolysis of fructose-1-p, fructose-1-p(aq) + h2o(l) - fructose (aq) + pi (aq) was allowed to proceed to equilibrium at 25°c. the original concentration of fructose-1-p was 0.2 m, but when the system had reached equilibrium, the concentration of fructose-1-p was only 6.52 x 10^-5 m. calculate the equilibrium constant for this reaction and the free energy of hydrolysis of fructose-1-p.
