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 the experiment, we observed that the Paramecium tetraurelia change their speed depending on whether the electrophoresis unit was either on or off. On this experiment our hypothesis …show more content…

First one is the independent variable which was Magnesium chloride (Mgcl2) that we would be changing. The dependent variable was the speed of the Paramecium and to see how Magnesium chloride will change it. We had two treatment levels they were our control group without Magnesium chloride and experimental group with Magnesium chloride. Our experiment was replicated twenty times. In our control group sample size, we added drop of Paramecium on 217 ml dryl’s solution. In our experimental group sample size, we added drop of Paramecium on 217 ml dryl’s solution with 15 ml of Magnesium chloride. In the beginning of our experiment, we took our sample size in a small container and then each was put in a separate depression slides and then we observed it under the microscope, as all of our group members observed we took down notes on what the speed of the Paramecium was. We measured the speed by putting a slide of a millimeter grid under the depression slides. Then we measured how many squares in the grid they moved within 10 seconds. To measure how fast, they were moving per second, we divided the squares by the seconds and that calculation give us their individual speed. Each square in millimeter grid was one millimeter. In this experiment, we predicted the speed of Paramecium will increase if we add Magnesium

Alka Seltzer Dissolve Lab Report

1721 Words | 7 Pages

For example, an experiment similar to this one could be how pressure could affect the time it takes for an Alka-Seltzer tablet to dissolve. Using A flask and rubber stoppers, you can compare the amount of time it takes for and Alka-Seltzer tablet to dissolve in regular room temperature water and room temperature water in a flak but with a rubber stopper stopping the air flow into the flask. This is related to the experiment performed above because the increase in pressure from the rubber stopper stopping the air flow in and out of the flask may affect the time it would take for the Alka-Seltzer tablet to dissolve. Another example of an experiment related to the one performed above is how the amount of water used to dissolve an Alka-Seltzer tablet effects the time it takes for one to dissolve. This also relates to the experiment performed above because it also affects how fast the rate of reaction is.

The “tail” segment measured initially at six millimeters and showed little signs of movement. Throughout the two week observation period, the “tail” segment did not grow at all and showed very few signs of vitality, but by the second week, a new head had started to form on the “tail” segment. Comparing the results of the experiment to my initial hypothesis, I was incorrect, the “head” segment grew more than the “tail” segment, although not by much. There could have been some error with the measurements because the tail segment did not really move at all and tended to shrink up

Dahpina Magna Feeding Rate Lab Report

1054 Words | 5 Pages

Introduction: In this experiment the rate of Daphina magna feeding was tested by the concentration of algae they were being fed. This experiment was performed in a three-hour lab period and was performed in groups of three. In this specific experiment the concentration of algae was what was being looked at. Many studies have been performed testing a similar study, the three studies that were relevant to this paper were studies regarding the concentration of algae and how it directly affected the feeding rate of the Dahpina magna. Each of the studies had other studies involved including temperate, swimming patterns and much more, but the concentration of food affecting feeding rate is what was focused on throughout these studies.

Sypharochiton Pelliserpentis Research Paper

1250 Words | 5 Pages

Sypharochiton pelliserpentis S. pelliserpentis has a dorsal shell that is made up of eight shell parts known as valves. These eight valves are bound together by a girdle which is strong and flexible and circles the valves. This particular species of chiton has its plate overlapping to resemble snake’s skin, thus, being colloquially referred to as the snakeskin chiton. The valves of S. pelliserpentis are very hard and allows the chiton to lay flat against a rocky surface. S. pelliserpentis has many miniscule holes in their valves which have delicate tentacles that can be extracted and are light sensitive.

Mean time fram will be deciided after allwing them to reach one of the ends of samll y- shaped open box. The Y-shaped box's both ends will be in same in distance from where the daphnia is placed constantlywith the help of dropper. This will minimize the chance of going to the nearest that is available. Light source is provided with the help of torch at one of the ends of the box and the other end will be covered with balck tape or paper in order to create darkness. Later based on the mean time that is recorded, each individual organism is placed at perticular place on water, within the mean time frame, the movement of the the individula towards a particular end is recorded.

Using the spines, individuals can send and receive a signal from each other, by its vibration reflection (Endo et al. 2010). It was stated that Hemicentetes semispinosus species have unique mechanism of recognition vibrations (Endo et al. 2010). It was received that typical adults have the spines, which are 16.8 mm in length and 8.55 mm in width (Endo et al. 2010). Spines serve as a protective «repellent» mechanism against predators (Speed and Ruxton 2005).

The Animalia Kingdom of Protista, is one of the most complex kingdoms to be discovered. Its organisms are greatly complex and unique, including but not limited to Euglenoid. For this investigation cells of Euglena gracilis were exposed to one of two different environments, before being observed for structural and behavioural differences under light microscopy. The E. gracilis were grown in a synthetic pond water ( 0.06g 〖CaCl〗_(2 ),1.00g NaCl and 0.04g KCl in 1L of DI water) and placed into either a sunlight exposed transparent container, or an opaque container kept in a dark surrounding. During testing the organisms were placed into a methyl cellulose solution to slow cell movement for accurate observations.

C Quinquecirrha Characteristics

The way that the medusa swims depends on the amount of prey around its environment which is why experts define them as a cruising predator. Its swimming patter is directional and at times the C. quinquecirrha may swim against the current making the C. quinquecirrha form into colonies. Additionally, a unique behavior of the C. quinquecirrha is that its swimming bells pulsates which helps provide the C. quinquecirrha with a supply of oxygen and it is a behavior that is inhibited by the

What is the effect of surface area to volume ratio on the rate of diffusion of the colour from the agar jelly cube? INTRODUCTION: Diffusion is the movement of spreading particles from high concentration to low concentration in an environment such as a cell. This major procedure is used in cells to source them with nutrients, water, oxygen, and to transport unwanted wastes such as carbon dioxide out of the cell or to different cellular organelles.

Compare And Contrast Earthworm And Jellyfish

580 Words | 3 Pages

The kingdom Animalia has a broad variety of members, such as the earthworm, the lion, and the jellyfish, who belong to different classes and are, therefore, placed all over the spectrum regarding complexity. By comparing the various body systems of these classes, it can be concluded that the Mammalia class is the most advanced. The earthworm, which is a member of the Clitellata class, is very primitive in regards to its respiratory system. The earthworm does not have a specialized system for respiration, but rather relies on diffusion to absorb oxygen.
