Abstract For this experiment we tested the effects of different adrenalin concentrations (0.001%; 0.01%; 0.1%) on the daphnia flea. The daphnia was placed on a slide with cover slip in order to examine its heartbeat by using the microscope. Aim In this Lab we will study the effect of different concentrations of adrenalin on the heart rate daphnia‚ the water flea. It is expected to recognize a threshold of the daphnia in its reaction the three different adrenalin concentrations‚ in terms of heart

Microscopes and Microscopy Introduction The purpose for including a lab on microscopy in his course is because it is a very important tool in making detailed observations. This lab helps the average person realize that there is much more to things than what you see with the naked eye. In the field of human biology microscopes are very important for many reasons. In the late 1500’s a scientist named Zacharias Janssen created the first microscope of it kind and now we have several microscopes

Shannon Yeh October 28‚ 2013 Animal Dentition Laboratory Assignment (Figure 1.) Tooth Sharpness (degrees) (Figure 2.) Relative Tooth Width (mm.) Results: The dental formula is a convention used by mammalogists to determine the tooth number and tooth arrangements. The dental formula is calculated by counting the number of incisors‚ canines‚ premolars‚ and molars present in the upper jaw (one side) and counting the number of incisors‚ canines‚ premolars‚ and molars

Version 2: Identifying Dominant Plant Species 1- Hypothesis Based on the results‚ the bunchberry plant‚ with a scientific name of Cornus canadensis‚ was most frequently seen in station four‚ the ecotone‚ and second most in station five‚ the forest which is most likely in the lower forest since it has a similar environment to that of station four‚ and third most in station three‚ the bog. It was not as frequently seen in areas of higher elevation such as the old field. It should be noted that

Biology 102 Lab Report: Ventilation and Oxygen Consumption in Fish Methods: The lab consists of two experiments repeated over a period one hour with fifteen minutes interval‚ in order to determine the effect of weight and temperature on ventilation and oxygen consumption of Carassius auratus‚ commonly known as goldfish. Each experiment was carried out by five groups. Measurement of ventilation was determined by recording operculum movement of the fish. Oxygen consumption was measured using oxygen

Molecular Biology Lab Report Mapping DNA using Restriction Enzymes Ava II and Pvu II to cut Bacterial DNA Abstract The objective of this project is to map bacterial DNA‚ which is derived from E. coli‚ using restriction endonucleases with gel electrophoresis. The DNA fragments‚ after cutting has occurred‚ are separated using agarose gel electrophoresis. The DNA fragments are placed in the gel‚ and an electric current is run through the matrix of the gel-like agarose. Migration of the fragments
