1. The process by which a water molecule is removed and a subunit is attached to form a macromolecule is called
A) dehydration synthesis
B) hydrolysis
C) condensation
D) both A & C
E) Both B & C
2. The ability of these organisms to perform oxygenic (plant-like) photosynthesis is
thought to have converted the early reducing atmosphere of earth into an oxidizing one,
which dramatically changed the life forms on Earth and provoked an explosion of
biodiversity. These organisms are
A) fungi
B) acidophiles
C) algae
D) cyanobacteria
3. A Dictyostelium (slime mold)
A) spends most of its life as an amoebe
B) begins to migrate and aggregate with others when nutrients are diminished
C) can differentiate into a stalk and spore mass
D) has spores that will scatter to give rise to another generation of amoebas.
I'm think the answer to number 1 is A, number 2 is D and number 3 is B but i just want to make sure. For number 3, A and B both seem to be correct... Thanks!
