shrimps (UNT Lab Manual‚ 2017). They normally inhabit fresh to partly salty water and feed on fish‚ carrion‚ plants‚ and detritus. Because they are completely aquatic‚ they rely on their gills for breathing‚ but can spend short periods of time out of the water if their gills will not dry. Like most crustaceans‚ they have a hard‚ calcified exoskeleton. The heart is located in the upper portion of the cephalothorax‚ which is located just in front of the first abdominal segment (UNT Lab Manual‚ 2017)

Kiley O’Toole Lab Report 3 Purpose The purpose of this lab was to uncover the number of layers of zinc atoms around a piece of galvanized iron. This was done by pouring the hydrochloric acid onto the galvanized iron‚ thus removing the zinc from the piece of metal. Laboratory Procedure 1. Measured and recorded the mass of a piece of galvanized iron using a centigram balance and a ruler 2. Measured and recorded the length and width of the galvanized iron using the ruler 3. Put the

simple mechanisms used to convert rotary motion into oscillating linear motion and vice-versa. The first of these is the slider-crank - a mechanism widely used in engines to convert the linear thrust of the pistons into useful rotary motion. In this lab we will measure the acceleration of the piston of a lawn mower engine at various speeds. The results exemplify a simple relation between speed and acceleration for kinematically restricted motions‚ which will discover. An adjustable slider-crank apparatus

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 part. Also it takes

Introduction The aims of the lab session was to familiarize with the principles‚ operation and application of a light spectrophotometer. This report discusses an experiment to study the relationship of absorbance and concentration‚ the interaction of electromagnetic radiant energy(ERE) and matter which is an important aspect of the Beer-Lambert ’s Law. This law states that the absorption of a compound is directly proportional to the concentration of that particular compound. This is because (a &

a definite relationship between the light intensity onto the leaf’s surface and the surface area of the leaf. Hypothesis I think the light intensity could affect the surface area in the following way: ·A higher light intensity could make the surface area of the leaf larger. The reason I think a higher light intensity could make the surface area larger is the fact that there would be a larger amount of chlorophyll‚ containing chloroplasts‚ for photosynthesis. By having leaves of a larger surface

Introduction: During this unknown lab report various test were performed to differentiate microbes from each other and to compare metabolic and biochemical process. The gram stain distinguishes between Gram positive and Gram negative bacteria based on the composition of the cell wall. The Gram stain procedure distinguishes between Gram positive and Gram negative groups by coloring these cells red or violet. Gram positive bacteria stain violet due to the presence of a thick layer of peptidoglycan
