Earthworm Lab Report
Introduction: There are times when it is necessary to go through something both inside and outside, literally, to learn. This was exactly the case with virtual lab #11 where the experiment called for an examination of an earthworm’s exterior anatomy and interior anatomy. The earthworm as a whole is considered the dependent variable as we cannot change it. However, the labels to be placed can be moved so they are the independent variables. My hypothesis is quite elementary. I believe that after studying the anatomy of an earthworm I will be better educated about it.

Procedure:
1. Begin by reading about earthworm activity by clicking the Earthworm Guide
2. For the external anatomy, move each of the corresponding labels to its correct “?”

    The independent and dependent variable for this experiment was the male fruit fly and the female fruit fly and the off springs. The controlled variables in this experiment were temperature, media, yeast, to much of the yeast would kill the fruit fly’s so the class had to make sure that to much was not poured into the vials. this had to be controlled well. 6- 10 ten grains of yeast with water and media. A change in temperature could also tamper with the experiment as well as messing with the vials all of these variables had to be controlled in order for the experiment to do…

    Purpose: In this lab, I will observe macroscopic changes that occur when mixing together certain chemicals and household cleaners. The mixing of the chemicals provided with each other and with acid/base indicators demonstrates how matter can change, and how chemistry can be seen with the naked eye. By mixing household cleaners with an acid/base indicator I hope to demonstrate how these changes can be related to everyday life.…

    The circulatory system is important in circulating blood, nutrients, oxygen and chemicals to the body. A circulatory system commonly consists of the fluid it contains, such as blood, a pumping vessel such as a heart, and the vessels, which carry the fluid through the body. In a closed circulatory system, the fluid, blood, is contained within the vessels as it circulates through the body. The Lumbriculus variegates, or blackworm, is commonly found in stagnant water along the edges of marshes and ponds. Blackworms have a closed circulatory system, which in the blackworm includes a large dorsal blood vessel [1]. Glucose is the most common carbohydrate and is classified as a monosaccharide and is a reducing sugar. Glucose is called blood sugar as well because it circulates in the blood. When blood glucose is high, the pancreas releases insulin, which then helps to transport glucose into muscle or liver cells. There, it's used for energy. If there's more glucose present than needed, insulin helps the glucose to be stored in adipose tissues as fat for potential future energy needs. One immediate effect of the breakdown and conversion of glucose into cellular energy is an increased metabolism, which can manifest itself in the form of increased heart rate, high blood pressure or some other form of arousal such as heightened mental alertness [4].…

    This report discusses an experiment to study the rate of aerobic cellular respiration in aquatic organisms which are Elodea (aquatic plant), Snail, and Goldfish, by measuring carbon dioxide production. Because ectothermic organisms (Elodea, snail, and goldfish) were placed in completely covered beaker, each organism would produce different amount of carbon dioxide. The objective of the experiment is to measure carbon dioxide production in three aquatic organisms, and to determine and compare the rate of cellular respiration in each organism. Aerobic respiration is the process which body obtains energy by using glucose + oxygen; this reaction takes place in mitochondrion in a cell; And the result of the reaction are carbon dioxide, water, and energy in the form of ATP ( adenosine triphosphate) (Hoefnagels, 2012). According to Biology 6th Edition, plants use light to convert atmospheric carbon (CO2) into carbohydrate (Johnson, 204). So I predicted snail would respire at the fastest rate and produce more CO2 because its weight was heavier than other two…
