A student wanted to study the effect of temperature on algae levels in a local stream. Which items are most useful for gathering data and most appropriate for communicating the results of her observation?

Nucleic acid certain protein cell membranes certain carbohydrates

Based on the diagram, which of the following best describes ways in which the physical appearance of h. neandertalensis and h. sapiens differ?

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.
