    Aim: To investigate how effect of Detergent Concentration (cont.) has on Membrane permeability of Beetroot cells. Hypothesis: I predict that as detergent concentration increases‚ the solution will become less clear‚ plus mass increases. The increases in mass will indicate that the water potential of the Beetroot cell is lower than that of the surrounding sucrose solution. The Beetroot discs will become flaccid and decrease in mass if the water potential of the surrounding solution is lower than

    Abstract The objective of this study was to observe and record the effects that exercise has on cardiovascular functions such as mean blood pressure‚ cardiac output‚ and total peripheral resistance by comparing each numerical function’s numerical data before and after exercise. Before exercise‚ the mean blood pressure (MPB) was 84.03 mmHg with a standard deviation of 10.3. After exercise‚ MBP was 92.19 with a standard deviation of 10.5. The cardiac output (CO) before exercise was 5.45 Liters/minute

    CELL THEORY – STEM CELLS Stem cells are a large focus of study in today’s biomedical world. “They are cells that exist in an undifferentiated state‚ and transform into differing tissue types depending on what the cells surrounding them are‚“ (National Institute of Health‚ 2012). Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition‚ they also serve as an internal repair mechanism inside many tissues‚ dividing without

    affect the cell membrane‚ thus would then releases the purple pigments out of the vacuole which causes the leakage of the purplish liquid.  Background Information The outermost layer is the cell wall‚ which is present only in plant cells and is made up of a carbohydrate called cellulose and also has other protein substances embedded within it. The cell wall is a rigid layer and gives structural stability to the cell and also limits the permeability of large substances into and out of the cell. Within

    Chemical Properties of Egg Tempera Art is traditionally viewed as a creative process far removed from science. However‚ beyond the imaginative efforts that contribute to the creation of a work of art are the physical materials that are used as the medium. While science is not an essential part of the thought and design process‚ an understanding of the chemical properties of different art media is integral to creating a work of art that will not only match the artist’s vision but will also stand

    Stem cells -are biological cells found in all multi cellularorganisms‚ that can divide (throughmitosis) and differentiate into diverse specialized cell types and can self-renew to produce more stem cells. In mammals‚ there are two broad types of stem cells: embryonic stem cells‚ which are isolated from the inner cell mass of blastocysts‚ and adult stem cells‚ which are found in various tissues. In adult organisms‚ stem cells and progenitor cells act as a repair system for the body‚ replenishing
