Exocytosis Lab Report Rough Draft Abstract: In Paramecium caudatum‚ trichocysts are 10^3 secretory vesicles that are released from the cytoplasm. We first observed how the presence of Alcian blue dye triggers normal secretion of trichocysts‚ and we then tested four different hypotheses in order to determine how the presence of Ca++ ions in the extracellular and intracellular environment affects the secretion of trichocysts. Our first our hypothesis tested whether extracellular calcium is

The sizes of Paramecium September 17‚ 2008 Wednesday Lab I am writing about the testing of sizes on Paramecium caudatum and bursaria and how they differentiate from one another. In comparing the two specimen’s size I found that the Paramecium caudatum was larger in size than the bursaria. Paramecia are unicellular organisms and are usually less than 0.25mm in length and covered with minute hair-like projections called cilia. They are characterized by their cilia which are

difference in invertebrate diversity between the mainland and Cow Island at the Queen’s University Biological Station. This was done by setting up multiple transect lines in both locations‚ all running 60 metres long with sticky traps and pitfall traps every 15 metres. The point-quarter transect method was used to record surrounding tree species and diameter to provide further information about the areas biotic diversity. It was hypothesized that there would be a difference in invertebrate diversity

The organic pollutants in the wastewater are used by the bacteria to grow and transform it to energy‚ water‚ CO2 and new cell material. Activated sludge systems are suspended-growth type and are used in conventional high-tech wastewater treatment plants to treat almost every wastewater influent such as ‚ brownwater

Wastewater recycling‚treatment in industry Purpose- Industrial activity worldwide uses 22% of the roughly 3.8 billion m3 of water consumed by human activity. So industry has a great need for water but given the tensions over water and the tougher legislation‚ it cannot continue to drain all this water from our planet’s resources. This is why the recycling of wastewater has become one of its top priorities. Water is often an essential part of industrial production. In the context of an ever more

Paramecium movement assignment: Answer the following questions and hand in at the beginning of the next lab. 1. Describe how Paramecium moves in aquatic environments? For the paramecium to move forward‚ its cilia beat on an angle‚ backward in unison. The paramecium moves by spiraling through the water. For the paramecium to move backward‚ the cilia beat forward on an angle at the same time. If the paramecium runs into a solid object‚ the cilia changes its direction and beats forward‚ which
