An Introduction to Thermal Physics 1
Problem 13P Use a Maxwell relation from the previous problem 1 and the third law of thermodynamics to prove that the thermal expansion coefficient ? (defined in Problem 2) must be zero at T = 0. Problem 1: Functions encountered in physics are generally well enough behaved that their mixed partial d

Why are action potentials usually conducted in one direction? a. The nodes of Ranvier conduct potentials in one direction. b. The brief refractory period prevents reopening of voltagegated Na+ channels. c. The axon hillock has a higher membrane potential than the terminals of the axon. d. Ions can fl

Human Heredity: Principles and Issues 11
How does DNA replication occur in a precise manner to ensure that identical genetic information is put into the new chromatid? See Figures 3 and 4. FIGURE 3 In DNA replication, the two polynucleotide strands uncoil, and each is a template for synthesizing a new strand. A replicated DNA molecule con

Households in Metro differ in their demand for public schools: Half are low demanders (L ) and half are high demanders ( H ). In addition, houses differ in value: Half are expensive (E ) and half are cheap ( C ). The location choices of households are based on property taxes and spending on public sc

Biology: The Dynamic Science 5
When tetrapods first ventured onto the land, what new selection pressures did they face? What characteristics might have fostered the success of these animals as they made the transition from aquatic to terrestrial habitats?
