I. Introduction: The purpose of this lab report is to differentiate between of Newton’s Third Law and Newton’s Second Law. Newton’s Third Law states that all forces come in pairs and that the two forces in a pair act on different objects and are equal in strength and opposite in direction. Newton’s Second Law states that the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object being accelerated. Using calculation equations for acceleration

Introduction The aim of this practical 1 is to determine the rate of photosynthesis by measuring the rate of oxygen production‚ which is a direct consequence of PSII activity. Results Graph 1 Graph 2 Discussion i. It took 2 minutes before any increase in the O2 concentration of the chamber was observed‚ it took 2minutes‚ after illuminating the leaf. ii. There are 2 main parts of the photosynthesis‚ light dependent part and light independent part‚ the O2 is released in last part which is light-independent

Introduction In this lab we had to design a system that would test if changing the mass‚ angle of release and length would have any effect on the period of a pendulum. Hypothesis As the length‚ mass and angle of release change‚ the period (T) will change for each one of these factors. Materials Lab stand Protractor Cardboard Fishing line Stopwatch Weights Hook for weights Tape Ruler Weighing scale Logger Pro Variables Independent Angle of release Dependent Period Length

these flasks. These flasks were incubated at 280± 20C on the shaker at 120rpm for 7 days. Mycelium growth was observed in each of these flasks. The mycelium growth was measured by filtering the contents using Whatman Filter paper No.1 from each of the flasks. The filter paper was washed with deionized water and then dried at 750C in a hot air oven till completely dried and was weighed in a pre-weighed Petri dish to obtain the residual fungal mass. The lowest concentration at which the fungal mycelium

encoded by EZH2‚ the EZH2 gene encodes part of the Polycomb group which make protein complexes that help to maintain genes transcriptional repressive state over successive cell generations. http://www.ncbi.nlm.nih.gov/gene/2146 Throughout this lab report template DNA that contains the gene EZH2 was provided‚ this will be amplified by a PCR and cloned into a vector. This Polycomb group proteins help maintain the cell identity during progress through chromatin

Michele Baden Bio 100 – 05 ALLELOPATHY INTRODUCTION The purpose of this lab was to observe the effects of chemical warfare among plants. Plant seeds compete with other plants and seeds‚ for sunlight‚ and nutrients in order to germinate. In order to win dominance over other seeds‚ and reduce competition‚ plants produce and release a chemical in order to prevent other seeds from germination. This type of chemical warfare is referred to as allelopathy. Allelopathy exists in many parts of the plants
