The kinetic energy of a moving car is less than the amount of chemical potential energy that is released when fuel is burilied in the engine. Which
statement best explains why this is so?
O A. The force of gravity transforms some kinetic energy into
gravitational potential energy.
O B. More of the car's energy is transformed into potential energy the
faster it goes.
O C. Some chemical energy is transformed into potential energy as the
particles in the fuel are rearranged.
D. Friction causes some of the energy released by the fuel to be
transformed into thermal energy.

integrated circuit (ic) is defined as a set of electronic circuits on one small flat piece of semiconductor material, normally silicon. a functional electronic circuit requires transistors, resistors, capacitors, inductors, etc., and the connections between them.

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
