Effects of Crossing Over in Sordaria fimicola Abstract Sexual reproduction in organisms is a cause for genetic variation. This can be seen through the process of meiosis in Sordaria fimicola because of the effects of crossing over and independent assortment that occur in meiosis I. Before performing this experiment we hypothesized that we would be able to see that crossing over did indeed occur in the S. fimicola. We tested our hypothesis by growing our own culture and observing it under a

Lab Report Background Information: Magnesium is an alkaline earth metal that has the symbol Mg. Magnesium is a fairly strong‚ silvery-white‚ light-weight metal (one third lighter than aluminum). In a powder‚ it heats and ignites when exposed to moisture and burns with a white flame that is harmful to the eyes. It is difficult to ignite in bulk‚ but once ignited‚ it is difficult to extinguish. Magnesium Ribbon is a long strip of magnesium metal about 3 millimeters wide and 10 meters long with

In this lab we tested to see if the amount of sunlight exposed to the basil seed‚ would affect the growth. The null hypothesis for this experiment was that there would be no statistical difference between the green‚ yellow‚ and red basil seeds’ growth. Three alternate hypotheses are: If we expose the green seed to 48 hours of sunlight and the yellow seed to 24 hours of sunlight‚ then the green seed with grow more than the yellow. The opposite of this hypothesis would alternate 2. Another alternate

Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab‚ we sometimes can observe only the physical part of the experiment‚ or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However‚ in order to understand and achieve more from just simply doing the experiment‚ we write lab report to more profoundly understand the internal meanings of the experiment we do‚ and

Gere Science - Perry 7-3 Kober Balloon Lab Report Problem: The goal of the balloon lab was to get a balloon attached to a line all the way across the room. One limitation was that we could only use one balloon‚ two straws‚ and tape. The circumference of the circle at its largest point couldn’t be larger than 100 cm. Procedure/Results: Trial Number | Distance Traveled (CM) | Time (sec) | Velocity (CM/sec) | 1 | 346 | 1.02 | 339.2 | 2 | 471 | .79 | 596.2 | 3 | 356 | .8 | 445 |

Chemistry Lab Report Water Hydration Introduction: A hydrated crystal or hydrated occurs when water becomes tightly attracted to a metal salt base on it’s polarity. The water molecules maintain integrity as molecules‚ however they are considered to be part of the formula of the hydrate. When the hydrate metal salt crystal is heated‚ the attractions to the water are broken by the heat energy and the water escape from the crystal. After heating the salt crystal is called as anhydrous‚ which

Safety Concerns in the Laboratory Safety goggles must be warn at all times during a lab session. This is very important because they protect your eyes from harmful matter such as chemicals‚ glass‚ and fumes. It is very important to note that they must be goggles and not glasses. Safety glasses may protect the eyes from flying debris and splashes but may not protect the eyes from gas fumes or splashes from underneath. Also‚ wearing contact lenses in a chemical laboratory without proper coverage
