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

1.What were the suggested next steps in your MyFoundationsLab Learning Path? My suggested next steps in MyFoundationsLab Learning Path was to continue on to the next module. It just said “Congratulations‚ you have mastered all available topics!”. I think i did a pretty good job on my learning path. I had to retake maybe three of the rest of them i mastered on the first try. MyFoundationsLab is a very good activity. Some of the coursework that was on there i havent seen since i was in high school

A Chromosome Study Lab An examination of the chromosomes of a cell under high magnification can give much information about an organism. Figure 1 shows the chromosomes of a somatic cell as they might appear in an organism if enlarged many times their natural size. A somatic cell is any cell making up the organism except for reproductive cells. In this investigation‚ it is expected that you: a. learn what a chromosome Karyotype is. b. prepare a Karyotype of chromosomes according to the instructions

Bleach Oxidation of 9-Hydroxyfluorene The purpose of this experiment was to oxidize an alcohol (9-hydroxyfluorene) to a ketone (9-fluorenone) using aqueous sodium hypochlorite (bleach) as the oxidizing agent‚ while introducing techniques used in microscale experiments. Reaction: Results 1. Recrystallized Product Yield Product yield = (actual yield/theoretical yield) x 100% 3mL 9-hydroxyfluorene x (1mL/1000mL) x (0.09 mol/L) = 2.7 x 10-4 moles 0.05g 9-fluorenone / (180.20g/mol) = 2.77 x 10-4
