microorganisms. An antibiotic should be selectively toxic to pathogenic microorganisms‚ should not incite an allergic response in the body‚ should not upset the normal microbial population of various body sites‚ and should not foster the development of drug resistance. Penicillin. Penicillin prevents Gram-positive bacteria from forming peptidoglycan‚ the major component of the cell wall. Without peptidoglycan‚ internal pressures cause the bacterium to swell and burst. Penicillin is not one antibiotic‚ but

in a religious magazine about the need for nonviolent resistance. Cesar Chavez chooses the rhetorical strategies of historical allusions‚ juxtaposition of violence and nonviolence‚ pathos‚ and assertive diction to persuade agricultural and other labor workers that nonviolent resistance is the right path to fair treatment and equal rights. Cesar Chavez uses historical allusions to persuade labor workers of the use of nonviolence resistance for achieving their fight for fair treatment. Allusions

the negative side of the battery would have a higher flow rate than the other wires. However‚ in the steady state the long bulb was actually brighter‚ and all the wires had the same flow rate. The new data allowed me to understand how different resistances in bulbs affects the brightness of bulbs in the circuit. Before this activity I knew that round

disobedience is the act of disobeying the law but in a peaceful manner while accepting the consequences. Many people feel it is wrong and disruptive; however‚ it is what makes people free and true to themselves and what they believe in. Peaceful resistance to laws positively impacts a free society because it is truly giving the people their freedom. It does not harm anyone‚ since it’s only done to prove one’s point or to let them stand up for what they believe is right. The normal population seems

Electricity and Magnetism Electricity Circuit symbols Potential difference The energy which is delivered to an electric circuit comes from the supply. The greater the potential difference of the power supply the more energy is delivered. Potential difference is measured in volts‚ which has the unit symbol V. Cells in series The more chemical cells that are connected in series the greater the potential difference that they supply. The potential difference of a number of cells connected

If temperature changes‚ the resistivity and conductivity will change accordingly. Temperature coefficient of resistivity () is a measure how temperature affects resistivity. We cannot measure resistivity directly- however by measuring the resistance of a wire with an ohmmeter‚ we can calculate the resistivity.
