Osmosis/Plasmolysis Lab Name: Problem: How do solutions of various salt concentrations influence osmosis in relation to an onion cell? Materials: (per student group): red onion epidermis forceps‚ dropper distilled water NaCl solution paper towels microscope slide cover slip Procedure 1. Make a wet mount of the red onion epidermis. 2. Examine under low power. When you have a clear view of several cells‚ switch to high power. Make a labeled drawing

Hello‚they call me Blue‚cause well I’m a carbon dioxide infused blood cell‚isn’t everybody?. I was made in the bone marrow along with all my brothers and sisters. Todays my 1st in the heart‚ and well I guess my first day to be alive really‚ I’m so excited. The heart would be my first trip well‚ anywhere really it’s truly amazing wait‚ unless you count the bone marrow. Did you know? I was only made about 5 seconds ago in your own bone marrow and now I’m headed for you’r heart. Okay so I’ll admit

BSC 120 Glucose Effect on Diabetic and Non Diabetic Blood Abstract: This lab was developed to investigate blood glucose and diabetes. Diabetes is a lifelong chronic disease in which there are high levels of sugar in the blood (Diabetes). The spectrophotometer was applied to this lab to determine the absorbance of blood glucose in diabetic and non-diabetic blood samples. In order to prove this‚ tests were conducted by taking the blood samples at different times right before a meal was eaten then

Investigation of Factors Affect Osmosis in Potatoes Aim The aim of the following experiment was to investigate the effect of varying the concentration of sucrose solution on osmosis in a potato. Preliminary Experiments One preliminary experiment was done before the main experiment. From the preliminary‚ we were trying to find out how osmosis actually occurred in potatoes‚ and gave us a vague idea on what the main experiment would be like. This preliminary will aid my prediction

Lindsay Turner 4/20/01 White Blood Cells Bacteria exist everywhere in the environment and have continuous access to the body through the mouth‚ nose and pores of skin. Further more‚ many cells age and die daily and their remains must be removed‚ this is where the white blood cell plays its role. According to this quotation‚ without white blood cells‚ also known as leukocytes‚ we would not be able to survive. White blood cells are our body ’s number one defense against infections. They

White blood cell (WBC)—A white blood cell is one of the three main types of blood cells. They are produced in the bone marrow and released into the blood. White blood cells are responsible for fighting infection. There are several kinds of white blood cells‚ including monocytes‚ lymphocytes‚ neutrophils‚ eosinophils‚ and basophils. White blood cells‚ or leukocytes (also spelled "leucocytes"; from the Greek word leuko- meaning "white")‚ are cells of the immune system involved in defending the body
