Name: Avishak Deb Roy Partners: Leevell Penn, Varugh, Butler Bio 101 Lab Report #1 02.22.2018 Swimming speed of paramecium tetraurelia in different levels of treatment. Introduction Paramecia is a unicellular Protista which are naturally found in aquatic habitats. It is easily cultured in the laboratory. It is oblong shaped and covered with short hairy structure called cilia. Paramecia does not pose any health or ethical concerns and the population can be maintained if there is a food source such as Enterobacter (Biological Foundation 7).
During this experiment, mitochondria were isolated from 20.2 grams of cauliflower using extraction buffer, filtration through Miracloth, and centrifusion. Twelve samples containing various volumes of mitochondrial suspension, assay buffer, DCIP, sodium azide, and citric acid cycle intermediates were prepared to be read by a spectrophotometer. The inclusion of the dye DCIP allowed for the absorbance of the reactions between the mitochondrial suspension and the TCA cycle intermediates succinate, malonate, and oxalate to be measured, as DCIP turns from blue to colorless as the activity of succinate dehydrogenase increases. Experimental Findings Increasing the number of mitochondria in the reaction did increase the reduction of DCIP relative to the amount of mitochondrial suspension present.
In this experiment we are observing how colder water is associated with the respiration of goldfish. Respiration, also known as breathing, is the process in which the body exchanges gasses and supplies oxygen. Goldfish use their gills to receive oxygen and get rid of carbon dioxide. Oxygen is an essential part to life because it is broken down to create ATP. ATP gives the goldfish energy to carry out it’s everyday goldfish activities.
Purpose/Question Does higher or lower than natural cricket environment temperatures affect carbon dioxide emissions from cellular respiration? Background A cricket’s ideal living temperature is about 21.1 to 32.2 degrees celsius, depending on the breed and location. If a cricket is in an environment that is at an ideal temperature, its heart rate will most likely speed up and it will be much more active, which will speed up the cellular rates of respiration. This is because crickets are ectothermic, or cold blooded.

Year 11 Stage 1 biology Bird Beak Summative Practical SACE# 798905X Aim: The aim of this practical investigation is to simulate the idea of adaption and evolution in times of drought in both valley and mountainous areas, through four common utensils representing four different types of bird beaks. Common dietary foods consumed by birds were substituted for toothpicks and beans. Hypothesis: In the valley were the toothpicks are found, the tweezer beaked bird will be the most affective at collecting food. This is due to the toothpicks resembling that of worms.
Abstract The purpose of this experiment is to test for mitochondrial activity by isolating different organelles using the differential centrifugation process. Studying mitochondria is extremely important because they control the death and life of the cell by regulating the apoptotic signals (Frezza et al 2007). Also they are responsible for the metabolic reactions (aerobic respiration) and the production of ATP (Frezza et al 2007). Three hypotheses were formed based on my knowledge.
Cell Respiration Lab Research Question What is the optimal temperature for germinating pea-seeds where the rate of respiration is the greatest? Background Information Cell Respiration refers to the biochemical process conducted by the cells of an organism that combines glucose and oxygen to produce energy in the form of ATP, along with two by-products, water and carbon dioxide. The equation representing this chemical reaction is shown below. C6H12O6 + 6 O2 6 CO2 + 6 H2O
My doctor said my vital signs showed I had a normal temperature of 98.6, a blood pressure of 140/90, a heart rate of 100, and an oxygen level of 80%. I took multiple tests, such as a chest examination where my doctor used a stethoscope to listen to my chest. Apparently I have crepitation’s. He can also hear me wheeze, and that it is clear I have difficulty breathing. I also took a spirometry test.
The Effect of Sugar Concentration on CO2 Production by Cellular Respiration in Yeast Introduction In this lab, our main focus was to find how sugar concentration affect yeast respiration rates. This was to simulate the process of cellular respiration. Cellular respiration is the process that cells use to transfer energy from the organic molecules in food to ATP (Adenosine Tri-Phosphate). Glucose, CO2, and yeast (used as a catalyst in this experiment) are a few of the many vital components that contribute to cellular respiration.
Your breathing rate is regulated by neural and chemical mechanisms. Respiration is controlled by neural messages from the brain to nerves that stimulate respiratory muscles. The main respiratory muscle is the diaphragm, which is controlled by the phrenic nerve. The rate, at which the nerves are sent messages from the brain, is controlled by the level of oxygen and carbon dioxide in the blood. There are chemoreceptors in the brain and the heart that sense the amount of oxygen, carbon dioxide and acid present in the body.
Cellular Respiration One of the main essentials of life that all organisms need in order to function in our world is, energy. We receive that energy from the food that we eat. Cellular respiration is the most efficient way for a cell to receive the energy stored in food. In cellular respiration, a catabolic pathway, which breaks down the molecules into smaller units, in order to produce adenosine triphosphate, also known as, ATP. ATP, is used by cells in the act of regular cellular operations, it is a “high energy” molecule.
Experiment 3: Cell Viability Testing and Counting with Trypan Blue Exclusion Method Anna Coretta R. Santos I. Introduction Cell viability assay plays a crucial role is in the cells of the cell culture. This assay can be used to identify the relationship of cell count from the cell’s behavior (Stoddart 2011). This test help researchers to determine the number of viable and non-viable cells in a cell culture. This assay helps in estimating the cell count of a cell culture and to determine if there is sufficient amount of viable cells in the cell culture that a person will use for future research (Riss et al. 2013).
Ventilation of a person through various activities Camila Gonzalez. This lab was made with the aim of proof that making different activities can alternate the ventilation rate, also is to see the variation of work our respiration system makes. We can see the different things and situations that can affect the normal process of ventilation and respiration, like the weather and the clothes that were limitations for doing this experiment because first the weather was so hot, so the person get tired early and began to ventilate faster and second the clothes wasn't appropriate for making the activities, because they also make weight and makes that the person get more tired. We use more than one person to make a comparison of the ventilation
