and time. Pre-Lab Questions: 1. Power is the rate at which work is done. The work divided by the time it takes for the work to be done equals power. 2. The unit for power is the Watt which is Joules/second. 3. One horsepower (hp) is 746 watts. Procedure: In this lab‚ we calculated the work performed and the power that person creates when he or she climbs and runs a set of stairs. Each step in the stair had a vertical distance (height) of 0.166 m. since there was a total of 10 steps; the total

Lab 11: Animal Behavior Introduction Ethology is the study of animal behavior. There are two specific categories of behavior: learned ad innate. Orientation behaviors place the animal in their specific environment. Animals move away from sensory input in taxis where as behavior is the response to sensory input. Stimulus’ of light‚ heat‚ moisture‚ sound‚ or chemicals are mostly found in taxis. Kinesis is the movement that does not result in orientation with stimulus. When animals respond to each

during meiosis I when pairs of homologous chromosomes split apart into different daughter cells. This haploid condition continues during meiosis II when sister chromatids split apart during the formation of four daughter cells. Score for incorrect answer: 0 General feedback 1 (May include media. Include graphic and file name): Remember that a diploid cell has pairs of chromosomes—each pair represents one chromosome that came from the organism’s male parent and another that came from the organism’s

Lab 1‚ Exercise 1 • Based on the information in Table 2‚ what patterns do you observe? The number of fish that I observed in a body of water increases until the dissolved oxygen was at 12 ppm. After that point‚ the number of fish declines slightly. • Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. When the dissolved oxygen levels increase‚ the number of fish that

Lab 5 DECOMPOSITION (Nov 2‚ 2011) Introduction: Decomposition is the breakdown of organic material into its smaller molecules and elements. (This term is generally considered as a biotic process but one may find it also used to describe an abiotic process‚ e.g.‚ due to weathering.) The decomposing organisms may use the release of elements for nutrients and by breaking apart the carbon-carbon bonds in organic matter this can release energy for them. These smaller molecules and nutrient elements

In this lab‚ we will be analyzing alum by doing three different tests. The first will be to find the melting point‚ the second to find the amount of water in alum‚ and the third is to find the percent sulfate. We expect the values to be close to the actual.
