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].…

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 independent variable is the one that is changed by the scientist. To insure a fair test, a good experiment has only one independent variable. As the scientist changes the independent variable, he or she observes what happens.…
The Hypolimnus Pedderensis is a Lake Pedder Earthworm. It lived in Tasmania Australia but went extinct in 1971. (Lake Pedder Earthworm). It only lived in a sandy, waterlogged habitat. Also, it fertilized soil as a niche. It was a segmented earthworm that has 129 body segments, was 50mm in length and 1.6mm in diameter. (Australia). Due to a flood at Lake Pedder, this earthworm is now extinct.…
My hypothesis is if the water temperature is hot then the life saver will dissolve quicker because the hot water has a greater chemical effect on the life saver than the other temperatures. I believe this is because the hot water is creating a chemical change and is changing the solid object into a liquid.…

Termites produce special chemicals within their bodies called pheromones. Because termites are usually found inside dark areas, pheromones help them communicate in these places. Past studies have suggested that ink inside ballpoint pens contains pheromones, causing termites to follow any trail created by the ink. If a pathway is drawn with an ink pen, then a termite will be attracted to the path and trace it due to the pheromones. To test the behavior of termites in relation with the presence of ink, we outlined two shapes with two different writing utensils and timed how long out of a sixty second time period that the termite spent on each path. The results showed that termites spend a substantially longer amount of time following the path of an ink pen than paths made from other writing utensils. The tested termites spent an average amount of 26.9 out of 60 seconds on paths made by the ink pen, but an average of only 2.4 of 60 seconds on a path made by a Sharpie marker. The p-value for the data is 0.00309 for the pen and 0.000214 for the Sharpie marker. The results suggest that termites are attracted to the pheromones contained in ink. This contributes to understanding how termites communicate and travel in areas without light.…
Pinworms are the most common type of worm infection, estimating that 10% of the population in the Untied States is infected and 30% of children worldwide. Pinworms are usually easily treated but the infection itself is very easily spread, making it persistent. This small…

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…
