In this lab we are going to be observing the decomposition of piglets over a month’s time. There are theory questions that have been given to us before and after the lab. We look back at our original theory to see where we went wrong‚ and then correct it. The lab was disgusting‚ surprising‚ and very interesting. The first questioned to be answered is which piglet decomposes faster‚ a piglet that is in its natural state‚ that is burnt‚ that is buried‚ and that is buried in a wooden box? With

Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that

Observing Protists through Hay Infusion Preparation Abstract: Protists are known to be the very first eukaryotic organisms on earth. The Kingdom Protista was first classified by Haeckel in the year 1866. Now‚ there are many known species of protists. After learning about protists in class‚ the group decided to observe the different species of protists found in pond water. The group prepared a preparation to be able to culture the protists until it was time to view them. After a few days‚ the

OBSERVING PLASMOLYSIS IN ONION CELLS (_ALLIUM CEPA_) I. INTRODUCTION Plasmolysis is the process in plant cells in which the cytoplasm is separated from the cell wall as a result of water loss through osmosis. Osmosis is a type of passive transport involving movement of water molecules across a partially permeable membrane. 1. RESEARCH QUESTION How does 15% NaCl solution affect the appearance of onion cells? 2. HYPOTHESIS If onion cells are submerged in solutions of NaCl of different concentrations

Observing the role of homeostasis in the body after exercise Biology (T): Functioning Organisms Biology Practical Report 0383210 Mrs Woinarski Due 14th November 2012 Introduction: Homeostasis plays a vital role in the maintenance of a normal environment in which bodily systems are able to function most efficiently. The importance of homeostasis can be seen in blood pressure and pulse rate‚ as measurements which are

How do bacteria affect human lives? Bacteria interact and are a constant in our day to day lives‚ perhaps more than suspected. Bacteria are often thought of as bad‚ however this is untrue‚ there is also many types of ‘good’ bacteria. ‘Good’ bacteria can benefit us by simply helping our digestive system work and helping us in the process of fermentation. Bacteria are extremely helpful in the production of many things such as fuel and medicine. But bacteria directly affect our production of

Virus vs. Bacteria Similarities – Virus vs. Harmful Bacteria Virus and Bacteria are similar. But yet they are different. Viruses and bacteria can make copies of themselves once they are inside a living organism (“J. L.”). They are both harmful bacteria and viruses. These bacteria and viruses can be helpful to the body. All diseases that people get are from virus and bacteria( Microbe Magic). Bacteria and virus are both microscopic organisms that have the same brain structure that why they are called

Explaining Bacteria Alexandra Solorzano 1E “ Hey Alex. Could you help your cousin with his homework?” “Okay‚ but I don’t understand what could be hard about fifth grade homework. Anyways‚ what are you learning about George?” “Well today my teacher started to talk about these things called Blackmeria? Or what is backferium?” “Umm I think you mean bacteria?” “Yeah! That’s it!” “Then I guess it’s your lucky day because right now in STT I’m in Cell Biology and we started to look into Bacteria too. Tell

The main objective of this lab is to see if the rate of cellular respiration will be affected if we change the food source from glucose to three different experimental variables (fructose‚ sucrose‚ lactose). Cellular Respiration is a process that generates ATP and it involves the complete breakdown of glucose to carbon dioxide and water. Carbohydrates‚ fats‚ and proteins can all be used as fuels in cellular respiration‚ but glucose is most commonly used as an example to examine the reactions and
