Fly Lab Shannon Ladd Introduction: Famers and herders have been selectively breeding their plans and animals to produce more useful hybrids for thousands of years. It was somewhat of a hit or miss process since the actual mechanisms governing inheritance were unknown. Knowledge of these genetic mechanisms finally came as a result of careful laboratory breeding experiments carried out over the last century and a half. A contributing geneticist named Gregor Mendel (1822-1884)‚ discovered through

franciscana are known to live in high salinity lakes that are often basic (Biology 108 Lab Manual 2015). Furthermore‚ A. franciscana feed on photosynthetic phytoplankton which inhabit areas of light availability but are also more susceptible to predation in highly-lit areas (Biology 108 Lab Manual 2015). Also‚ A. franciscana can withstand a broad range of temperature except extreme values may affect survival (Biology 108 Lab Manual 2015). In this experiment‚ the habitat

The reason for this lab was to use statistical concepts learned in lecture to analyze data and to become more familiar with the lab equipment. Repeatability measurements were taken on a bolt to get the total length‚ and

Lab Report Microscopic Study: Investigating Osmosis in Red Blood Cells Lab Report Investigating Osmosis in Red Blood Cells Introduction: The flow of water across a permeable membrane is called osmosis‚ and during this process‚ water moves down its concentration gradient. A solution surrounding a cell is hypertonic if it contains more solute particles than the inside of the cell‚ and the water will move out of the cell into the surrounding hypertonic solution by osmosis. If the solution

The different methods of measuring acids and bases in a solution By Starsky Intro to Biology September 26‚ 2011 Lab Partners: Kristen‚ Tania and Betty Introduction When using different methods to measure pH levels there are some tools that can be useful. Some more than others but by putting into action the different methods it may determine which tools will work best and give the best

1 Measuring and calculating equilibrium constants Clearly‚ if the concentrations or pressures of all the components of a reaction are known‚ then the value of K can be found by simple substitution. Observing individual concentrations or partial pressures directly may be not always be practical‚ however. If one of the components is colored‚ the extent to which it absorbs light of an appropriate wavelength may serve as an index of its concentration. Pressure measurements are ordinarily able to measure
