An organism's activity is dependent on the activity of its independent cells. B. Metabolism and biochemistry occur within cells. C. Hereditary information is stored in cells and is shared between cells during cell division. D. All cells contain a nucleus for the storage of genetic material. E. All cells in organisms of similar spec...

Aquifer - answer-underground geologic unit that is saturated with water which contains sufficient permeability to yield the water to wells. Unconfined aquifer - answer-Water surface is at atmospheric pressures. Confined aquifer - answer-Aquifer that is confined by an impermeable material, such as clay or shale, resulting in the aquifer being under pressure. Permeability - answer-A measure of the ability to transmit fluids based on the material within the aquifer. Transmissivity - ans...

Thermodynamics The study of energy and itrs transformations Thermochemistry The relationships between chemical reactions and energy changes Electrostatic Potential arises from the interactions between charged particles Eel = k(Q1xQ2)/d k = 8.99x10^9 J-m/C^2 the charges of Q1 and Q2 are typically on the order of magnitude of the charge of an electron (1.60x10^-19 C) When Q1 and Q2 are of the same charge, they will repel, making Eel a positive number When Q1 and Q2 are opposite...

Gravitational Field - ANSWER-A region in which an object that has mass experiences a force Field Lines - ANSWER-Arrows which indicate the direction and relative strength of a field. Arrows show the way in which a rest mass would experience the force of attraction. Equipotentials - ANSWER-Lines drawn to indicate points of equal potential. Cross field lines at 90 degrees Newton's Law of Gravitation - ANSWER-Every particle in the universe attracts every other particle with a force that is ...

ME 2334 Thermodynamics Exam 1 1.19) a large fraction of thermal energy generated in the engine of a car is rejected to the air by the radiator through the circulating water. should the radiator be analyzed as a closed or open system? - Answer- Open because air goes in and out and there is energy exchange with the surroudings 1.36) temperature of a system rises by 130°C during a heating process. express this rise in T in K. - Answer- 130 K 1.55) the barometer of a mountain hiker reads...

BIOL 213 FINAL EXAM BANK: EXAM 1: EXAM 1 HW: 1. If phosphorus-32 has an atomic number of15, how many neutrons does it usually have? - 17 2. The seed of a desert plant may be dormant for many years without growing, but is still considered to be alive because it? - Possesses heritable information 3. A “rogue” scientist is featured in many movies, but actual scientific discovery and advancement is done as a community, involving lots of dedicated scientists. Once a hypothesis has been supported ...

CHEM 103 MODULE 3 NOTES. 3.1: THERMOCHEMISTRY Thermodynamics is the study of the relationship between heat and other forms of energy, particularly mechanical work. Thermochemistry is the part of thermodynamics that deals with the quantity of heat given off or absorbed during a chemical reaction. The quantity of heat given off or absorbed during a physical change or temperature change can also be studied, and we will refer to this process as calorimetry. In order to adequately discuss thermoch...
