Work and Energy. 1. What is the work done by a force of 20 N acting through a parallel distance of 8.0 m? What force will do the same work through a distance of 4.0 m? [160 J‚ 40 N] 2. A push of 120 N is applied along the handle of a lawn mower producing a horizontal displacement of 14.0 m. If the handle makes an angle of 30.0o with the ground‚ what work was done by the 120 N force? [1.45×103 J] 3. A rope making an angle of 35.0o drags a 10.0 kg toolbox a horizontal distance of 20

Campbell’s Biology‚ 9e (Reece et al.) Chapter 31 Fungi Though fungal divisions have traditionally been based on modes of sexual reproduction‚ molecular considerations are becoming more important. Consequently‚ no emphasis has been placed on the vagaries of sexual and asexual reproduction among various fungi in this Test Bank. Instead‚ new questions assess students’ abilities to think logically about fungal morphology‚ genetics‚ and ecology. Two new sets of scenario questions deal with the biology

Chapter 2 Terms Matter - anything that takes up space and has mass. Element - substance that cannot be broken down to other substances by chemical reactions. Compound - substance consisting of two or more different elements combined in a fixed ratio. Essential Element - the 20-25% of the 92 natural elements an organism needs to live a health life and reproduce. Trace Elements - required by an organism only minute quantities. Atom - the smallest unit of matter that still retains the properties

Chapter 11: Cell Communication Concept 11.1 External signals are converted to responses within the cell. I. Evolution of Cell Signaling 1. signal transduction pathway. a specific cellular response in a series of steps 2. signaling mechanisms first evolved in ancient prokaryotes and unicellular eukaryotes‚ then adopted for new uses 3. quorum sensing. allows bacterial populations to coordinate behaviors to carry out activities only productive when performed by a given number of cells

Chapter 4 Microscopes Two important factors in microscopy are: 1) Magnification: an increase in the object’s apparent size compared with its actual size. 2) Resolving Power: the ability of an optical instrument to show two objects are separate. Three types of microscopes: 1) Light Microscope (LM) M: 1000x RP 0‚2 micrometer (small bacterial cell) 2) Electron Microscope (EM) uses a beam of electrons to resolve electrons‚ better resolving powers than light microscope M:100‚000x RP 0
