In the lab with germinated and dry peas along with glass beads, determining the rate of respiration in each different type of seed was the goal. The hypothesis stated that since the germinated peas were still alive, they would contain a higher rate of respiration needed to remain healthy compared to the dried peas and glass beads.…
Experiment two observing the respiration of dry ungerminated peas. Based on the class data collected it is clear the ungerminated peas consumed very little oxygen. The ungerminated peas require…
The purpose of this lab was to explore the growth and developmental differences in different liquids when exposed to a lima bean over the course of 10 days. by looking at the results it is evidence that the pond water is the greatest factor of liquids compared to milk and sprite. My hypothesis of pond water being the best liquid to grow a lima bean plant was correct the lima bean had grown to 13 centimeters but while doing this experiment I was surprised with the results of milk hoping it to be better and hoping for more growth due to its nutrient content before completing this lab I had the impression that milk would be the second most growth in the plants due to it protein and nutrient content. But I believe that these results were not…
Materials and Methods This experiment required 30 Alaskan Pea seeds, 3 pots (4 1/16in x 2in), two 60in Vigoro Sturdy Bamboo Plant Stakes, one API Nitrate (〖NO〗_3^( -))Test Kit, one API Phosphate (PO_4^(-3)) Test Kit, half of one bag of 3.7L bag of Earthgro: The Natural Choice Potting Soil, 10 Red Wriggler Earthworms (Eisenia foetida), 2 mesh strainers (1 small, 1 big), one 400mL beaker, 4 glass tubes, one 12in ruler, Garden Clippers, Greenhouse, Greenhouse Thermometer, Greenhouse Watering Can, and a Sink, 4 Paper Towels, and a 3inx2in rectangular container. I labeled the 3 pots with orange tape, 1 was labeled experimental phosphate, 1 was labeled experimental nitrogen and the last one was labeled control. First I obtained 3 pots and one 3.7L…
Examining the activity rate using DCIP and a spectrophotometer of succinate dehydrogenase isolated from Brassica oleracea mitochondria via mechanical disruption and differential centrifugation Introduction Mitochondria are important cellular organelles located in the cytosol of cells and is believed to have originated through an endosymbiotic relationship. The unique double layered membrane structure is responsible for the production of the primary energy currency of the cell; adenosine triphosphate or ATP. Small amounts of ATP that the cell can immediately use as an energy source are available during glycolysis of glucose to pyruvate, but the amount of ATP derived from pyruvate can be greatly increased through further processing. Through reduction-oxidation reactions and the electron…
Lima beans are edible flat whitish beans and are good to use for any experiment because they represent the human body in that they both go through all of the same processes of growth and development. This lab uses lima beans in order to determine whether they were viable or not. If a bean is viable, it means that it is alive: able to grow and develop. The two ways to find out whether a bean is viable or not, are a tetrazolium test and germination test. Tetrazolium is a chemical that turns red in the presence of hydrogen ions. All living organisms release hydrogen ions every day and therefore, it was possible to see whether the lima beans were viable or not using tetrazolium. This is a result…

Structured questions 11 The apparatus below is a simple respirometer. Some students in a CAPE™ Biology class used it to determine the rate of oxygen uptake by germinating mung beans. coloured water a b c d capillary tube meniscus attached graph paper or ruler soda lime Explain how the apparatus shown in the diagram can be used to measure the rate of oxygen uptake in mm3 min−1 g−1. Apart from lack of a control, describe two other limitations of the procedure described in a. Describe a control which should be set up to obtain valid results. The results in the table below were obtained by the students when measuring the uptake of oxygen by the mung beans.…
Culture often times can impact one’s perspective on things in the world. Culture does inform the way we view the world and others. There are many factors that influence a person's perspective, culture is one of the most important elements in shaping the way he/she views the world. We are surrounded by culture and see differently everyday. Many believe that culture influences how we judge and see things around the world.…
3.Describe and explain the relationship between the amount of oxygen consumed and time? The amount of oxygen consumed was greatest in germinating peas in warm water. The oxygen consumption increased over time in germinating peas.…
What happens when a person of one culture tries to enter another one completely different? Our cultural background has a huge influence on how we see the world. It's a very complicated task for these people to get involved in a completely different environment than the one they are used to, since they were raised one way they see the world in a particular way. For example; the Muslims that have a totally different culture than ours think that we live among sin because of how we dress, the things that we do, etc. On the other hand us Americans are a bit more open minded because of our very extended cultural mixture.…
In this lab the rate of germination in relation to temperature was observed testing the hypothesis, if the seeds are exposed to cold temperatures then they will not germinate. In the standard germination test a total of one hundred corn seeds were divided into four groups of twenty-five and each group was used to make a ragdoll. The rag dolls were germinated in room temperature. In the cold test one hundred corn seeds were placed on four layers of moist paper towels in the bottom of a metal tray, covered in moist soil and then were placed outside for eight days. After eight days they were allowed to germinate at room temperature for six days.…
The goal of this experiment was to explore how temperature would influence the rate of cellular respiration of beans. It was hypothesized that as the temperature of the beans increased, the rate of cellular respiration would increase as well. In this experiment, the independent variable was the temperature, which gradually increased as time went by, and the dependent variable was the rate of cellular respiration, which was shown by the change in the amount of CO2 and O2 in the container. During the experiment, 25 cooled beans were put into a breaker, and another 25 cooled beans were put into a plastic container. Then, a temperature sensor was put into the breaker to measure the change in temperature of the beans, and two gas pressure sensors…
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…
