CHOKE COIL IN TUBE LIGHTS… We saw in the last section that gases don’t conduct electricity in the same way as solids. One major difference between solids and gases is their electrical resistance (the opposition to flowing electricity). In a solid metal conductor such as a wire‚ resistance is a constant at any given temperature‚ controlled by the size of the conductor and the nature of the material. In a gas discharge‚ such as a fluorescent lamp‚ current causes resistance to decrease. This is

process in which a bacterial cell takes up extracellular DNA. This can be especially useful for bacteria in order to acquire certain traits such as: antibiotic resistance‚ synthesis of catabolites‚ or any other trait that would help improve its survival. However‚ not all bacterial cells are naturally competent (able to naturally take up extracellular DNA). There are several techniques that can make cells artificially competent‚ some of which will be discussed later. Bacterial transformation was

Cockroaches and Hemolymph Concentration in the Body Abstract This lab was conducted to determine the concentration of hemolymph in the body of a cockroach. It was done by making serial dilutions to make a standard graph by injecting a dye into a cockroach and determining the concentration at different times with the use of a spectrophotometer to find the optical density which is measured in absorbance. Results showed that the concentration was not within the pre-experiment research range

When I was skimming pages when I saw this big painting the one that caught my eye right away. "The Tube Train" by Cyril E.Powers about 1934 (pg.203). I was so fascinated with this image‚ the urban theme and the nice colors. I notice the use of complementary colors; most of the picture is done in yellows and dark violets and reds which are all on opposite sides of the color wheel. The moment when I glanced at this painting my first question was “where are these people heading?” I believe they
