Lab Report 3: Daphnia‚ Human and Crayfish Cardiac Activity Introduction An electrocardiogram‚ abbreviated as ECG in this report‚ is a visual representation of an organism’s atrial and ventricular depolarization and repolarization. Previous research has shown that although there is variability in the amplitude and shape of the waves of ECG‚ dependent on the subject’s health‚ it follows a universal pattern that can be used effectively for biometrics. The experiments discussed in this lab report were

fillings‚ and sodium chloride. To remove the iron fillings from the mixture I used a magnet and scanned it across the entire mixture and the magnet forced picked up all the iron pieces. Then to separate the sand from the rest of the mixture I heated the mixture with water in a beaker and when I poured the heated liquid into a cup the sand remained in the bottom of the beaker. Lastly to separate the benzoic acid and sodium chloride I used a filtration system and the sodium chloride and water drained

Throughout the week in the toxicology lab‚ I was acquainted with distinctive sort of tests and I got the opportunity to find out about the following: 1- hTSH test (Human thyroid stimulating Hormone): - Add calibration and +/- controls‚ before starting the punching process. - Add hTSH assay buffer + stock solution. - Put the plate on a fast quick shaking for 10mins‚ and afterward 4 hours moderate shaking at room T° -Add washing solution. -Add enhancement solution‚ and read the result.

Stoichiometry lab 1 Purpose: The purpose of this lab is to find the limiting reactant‚ also to find the percentage yield and percentage purity of the reaction that happens between Calcium Chloride and Sodium Carbonate. The other purpose was to know how the reaction can be balanced and created. Hypothesis: In this lab we are going to see a precipitation reaction. This is a reaction where two soluble salts Sodium Carbonate and Calcium Chloride are added together and the result is the precipitation

Lab #1 ‐ Introduction to the Microscopy & Observation of Prokaryotic and Eukaryotic Cells Introduction Many of the cells and organisms that you will be studying are at the lower limits of visibility of light microscopes; therefore‚ it is extremely important that you attain critical lighting and focussing. It is also important to handle the microscope competently to avoid damaging either the microscope or the preparation you are studying

BIOLOGY OSMOSIS LAB REPORT 1. Research Question/ Aim How do the different sodium chloride concentrations of solutions affect the length (measured in mm) and mass (measured in grams) of potato cores placed in them overnight (approximately 10 hours)? 2. Hypothesis Alternative hypothesis: As the concentration of sodium chloride in the solution increases‚ the mass of the potato cores will decrease. If the solution they are in has a lower water potential than the potato cores‚ there will be
