reproductive. Orientation is when the organism is placed in their beneficial environment consisting of two behaviors‚ taxis (movement directly towards or away something) and kinesis (random movement). Reproductive is detected using drosophila in this lab‚ it consists of finding courting and mating with another of the species Agnostic behavior is found in a situation where the animal feels threated by another‚ leading to the organism looking bigger or more threatening to the opponent. Within the Agnostic

& Ohm’s Law Abstract: In this lab‚ students were introduced to the field of electrical engineering. The objectives of the lab were to determine the resistance of a resistor using various methods and to also verify Ohm’s Law. In the lab‚ the students were instructed to calculate the resistance by using color codes‚ measuring the resistance using a Digital Multi Meter‚ calculate the average resistance from 10 voltage and current measurements‚ and find the graphical resistance using a trend

Peaceful resistance to laws is a positive impact a free society because for example like Rosa Parks she helped the colored people a lot. She fought for what she thought was the right thing to do because the colored people were being pushed around without having their ideas spoken out. She was taken out the bus she was riding in because she didn’t want to move from the seat she was sitting in and she was pushed out the bus and was told a lot of bad racist things that I don’t think any one deserve

transformations are that light must be absorbed by a compound in order for a photochemical reaction to take place‚ and that for each photon of light absorbed by a chemical system only one molecule is activated for subsequent reaction. This "photo equivalence law" was derived by Albert Einstein during his development of the quantum (photon) theory of light. Absorption of visible and/or ultraviolet light by a molecule transfers all the energy of the photon to one molecule. This is sufficient energy to excite

Introduction! ! The Michelson Interferometer is commonly used to determine the wavelength of light or measure very small distances. It was invented by Albert Abraham Michelson and is commonly used in optical interferometry‚ a branch of physics involving a family of techniques one could use to extract information about waves by superimposing them. ! ! The original application of the Michelson Interferometer was to the famous Michelson-Morley experiment in 1887. Prior to Einstein’s
