Q: Answer the following question given this paragraph: Endothermic reactions absorb energy from the surroundings as the reaction occurs. When 1 mol of calcium carbonate decomposes into 1 mol of calcium oxide and 1 mol of carbon dioxide, 177.8 kJ of heat is absorbed. The process is shown visually in Figure above (B). The thermochemical reaction is shown below. Q: What kind of reactions absorb energy from their surroundings as they occur? A: | OPTIONS:
- exothermic
- hydrostatic
- autotrophic
- endothermic
A: endothermic

Q: Answer the following question given this paragraph: Q: The logistics of carrying out cellular metabolism sets limits on what physical property of the cell? A: | OPTIONS:
- surface
- composition
- layer
- size
A: size

Q: Answer the following question given this paragraph: 12.4 Viscosity and Laminar Flow; Poiseuille's Law Laminar flow is characterized by smooth flow of the fluid in layers that do not mix. Turbulence is characterized by eddies and swirls that mix layers of fluid together. Fluid viscosity is due to friction within a fluid. Representative values are given in Table 12.1. Viscosity has units of. Q: What property is characterized by eddies and swirls that mix layers of fluid together, unlike laminar flow? A: | OPTIONS:
- combustion
- compression
- evaporation
- turbulence
A: turbulence

Q: Answer the following question given this paragraph: In the chest, the trachea divides as it enters the lungs to form the right and left bronchi . The bronchi contain cartilage, which prevents them from collapsing. Mucus in the bronchi traps any remaining particles in air. Tiny, hair-like structures called cilia line the bronchi and sweep the particles and mucus toward the throat so they can be expelled from the body. Q: In the chest, the trachea divides as it enters the lungs to form the right and left what? A: | OPTIONS:
- alveoli
- ventricle
- atrium
- bronchi
A: bronchi
