Atp synthase is the protein complex
a. transfers electrons to oxygen in the final step of the respiratory chain.
b. rotates when atp is hydrolyzed in the mitochondrial matrix.
c. captures the potential energy of the proton gradient in the intermembrane space as the chemical energy in phosphate bonds of atp.
d. transfers electrons from the inner mitochondrial space to the mitochondrial matrix. e. creates a proton-motive force when glucose is oxidized.

Consider darwin's first writings on the theory of natural selection. an important point of darwin's essay on the principle of population, written in 1798, was a peer's observation that in nature plants and animals produce far more offspring than can survive, this observation can be attributed to a) charles lyell. b) thomas malthus. c) jean-baptiste lamarck. d) johann friedrich meckel.

Subduction zones form when an oceanic plate collides with another oceanic plate or continental plate. the continental crust is lighter and less dense than oceanic crust. continental crust's density is approximately 2.7 grams per cubic centimeter. oceanic crust is thinner and the average density is about 3.3 cubic centimeters. when the two crustal plates converge the oceanic plate always bends and subducts beneath a continental plate. once the oceanic crust subjects, the rocks are subjected to changes in heat and pressure. because of this, we would expect to find rocks in the area of a subduction. a) clastic b) igneous c) metamorphic d) sedimentary
