Electric Eels. Electric eels and electric fish generate large potential differences that are used to stun enemies and prey. These potentials are produced by cells that each can generate 0.10 V. We can plausibly model such cells as charged capacitors. (a) How should these cells be connected (in series or in parallel) to produce a total potential of more than 0.10 V? (b) Using the connection in part (a), how many cells must be connected together to produce the 500-V surge of the electric eel? 24.16 . For the system of capacitors shown in Fig. E24.16, find the equivalent capacitance (a) between b and c, and (b) between a and c.
BSCI201: Anatomy &Physiology Chapter 4 (Tissues) Notes- Part 1 by Mehrnaz Ighani .Individual body cells are specialized which means each type performs specific functions that maintain homeostasis . Tissues: groups of similar cells that perform common and related function . Histology: study of tissues . 4 basic tissue types: (Fig. 4.1) 1. Connective: supports and binds other tissues together 2. Muscular: movement 3. Nervous: internal communication 4. Epithelial: forms boundaries between different environments . Epithelial tissue: a sheet of cell that covers body surfaces or cavities 2 main types: 1. Covering and lining epithelia: an external/internal surface Ex. Skin 2. Glandular epithelia: secretory tissue in glands Ex. Salivary gland
