Stephen Pidliskey 09/15/07 P1 Park ISOPOD BEHAVIOR LAB REPORT Background Information: In our lab we were working with isopods‚ also known as pill bugs or rollie pollies. The isopods that we worked with were land isopods. They like to live in moist places under untouched objects such as boards‚ bricks‚ rotting logs and or rocks. Basically‚ they will live anywhere! If you are lucky enough‚ you can even find them next to buildings where it is moist and if there is food. All living organisms like

its very common that with heat applied to something‚ the ’object’ expands‚ this is seen with metals. Due to this‚ we assumed that the same would happen to animal and plant cells and the cell membrane. It’s also believed that the low pH solution of vinegar (2.4) would eat away the cell wall and plasma membrane‚ which would then cause a chemical reaction to the cells structure. It was also considered that if the cell received did heat and exposure to a pH solution we would have total cell failure in

This altering between beer and apple vinegar probably contributed to his early success. Apple vinegar has antibacterial properties. Now my family comes from a long line of coal miners and moonshiners. A commonly overlooked trick from keeping your moonshine from developing a metallic‚ penny-like taste is to clean your copper pot on a regular basis. Since most cleaners are poisonous‚ I was always taught to clean your copper pot with ketchup or apple vinegar. Both products are nonpoisonous and have

This occurs because the pH of the milk has been changed. Casein‚ one of the main proteins in milk‚ is a weak soluble‚ meaning it doesn’t dissolve well in water. When vinegar is added to the milk‚ it causes the milk to become more acidic‚ and the protein casein to unfold. By tampering with the usual shape of casein‚ the protein now interacts with other denatured proteins and results in clumping (Lawandi‚ 2015). These clumps

some of the basic values and beliefs of China. Dr. Snyder used a famous Chinese painting to discuss the teachings of China. This painting is called the vinegar tasters and with this painting comes a small story. In the painting three men surround a vat of vinegar and Dr. Snyder said that the vinegar represents life. All three men taste this vinegar and each have a different

pores in the membrane that allow substances to move in and out of the cell. Way Cool! Recall that the function of the cell membrane is to control the internal balance of the cell. It helps to maintain homeostasis. In this lab you will use vinegar‚ an acid‚ to dissolve the shell off of the egg to expose the membrane. When you place the egg in water you will be able to observe osmosis in action over the next few days. Remember to handle the egg with a lot of care—and don’t forget to wash your
