Mental experiment. Picture in your mind the velocity vs. substrate concentration curve for a typical Michaelis-Menten enzyme. Now, imagine that the experimental conditions are altered as described below. For each of the conditions described, fill in the table indicating precisely (when possible) the effect on Vmax and KM of the imagined Michaelis- Menten enzyme.

Experimental condition Vmax KM

a. Twice as much enzyme is used.
b. Half as much enzyme is used.
c. A competitive inhibitor is present.
d. An uncompetitive inhibitor is present.
e. A pure noncompetitive inhibitor is present.

Indicate whether the following statements about the biases in the fossil record are true or false. a) inland species are more likely to be preserved than marine species b) organisms with hard body parts are more likely to be preserved than are those composed soft tissues. c) species that existed over a larger area are more likely to be preserved than species existing over a smaller area. d) organisms that lived very long ago are more likely to be found as fossils than organisms that lived relatively recently e) the fossils of larger organisms are more likely to be found than the fossils of smaller organisms

Recombinant dna (rdna) creates offspring which are genetically identical to the parent is the process of breeding only organisms with desirable traits involves the removal of the nucleus of a cell combines genes from organisms of different species in a lab
