The purpose of lab number thirteen was to examine the response of the daphnia to a chemical stimulant. Also examined was how human resting heart rates differed from the daphnia’s. Stimulants are any substances that raise the levels of activity in the body. Stimulants could be a number of things such as physical or chemical. Physical stimulus usually deal with something that affects the five senses such as sight‚ hearing these could be attributed to loud noises or too much light going into your eye

Abby Goldschmidt Honors Biology 2° Mrs. Gempel September 3‚ 2015 Daphnia Lab Results Paper Abstract The goal of the study was to observe the effects of multiple chemicals on a Daphnia magna’s heart-rate compared to a control (pond water). The different chemicals were caffeine and alcohol. The heart-rate was the main variable in this experiment. The Daphnia’s heart-rate was observed for 15 seconds and then multiplied by 4 to show its heart-rate in one minute. This was repeated 4 times for each

These differences are perhaps most highlighted in the medical field where stereochemistry of a molecule can be the difference between having a medically active‚ effective drug and a toxic‚ potentially

Lab Report 1: Measurement Lab Date: January 17‚20XX Lab Partners: XZ Report Date: January 24‚2014 Report Written by: XXXXXX Introduction: Measurement is a form of quantitative observation. The ability to make accurate and precise quantitative observations is crucial to science. Accuracy in this sense refers to the closeness of the measured result to the hypothetical “true” value (Motzny 2014). Having a precise measurement implies its exactness.

Purpose: In this lab‚ a mixture of naphthalene (C10H8)‚ common table salt (NaCl)‚ and sea sand (SiO2) will be separated using the separation techniques in order to demonstrate the properties of mixtures and their ability to be separated by physical means. INTRODUCTION: This lab was based on the separation of the components of a mixture. A mixture can be defined as a physical combination of two or more pure substances. Separation techniques are used to separate components that are not chemically

As you can see in table 1‚ the percent bound of BSA-PR at pH 4 (61.543%) was highest compare to other pH. pH 6 has the percent bound of 3.569%‚ pH 8 has the percent bound of 2.330%‚ and pH 10 has the percent bound of 2.309%. pH 6‚ 8‚ and 10 do not have an optimal binding for bovine serum albumin and phenol red because they have very low percent bound (refer to table 1)‚ mostly is the free phenol red. Therefore it matches with the prediction

AP BIOLOGY Lab 5 Cellular Respiration Objective: To calculate the rate of CR from the data. To then relate gas production to respiration rate. Then test the rate of CR in germinating versus non-germinating seeds in a controlled experiment and then test the effect of temperature on the rate of CR in the germinating versus non-germinated seeds in a controlled experiment. Analysis: 1. The CR is higher in the germinating peas in the cold water rather than in the beads or non-germinating peas
