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

ORGANIC MATTER AND INORGANIC MATTE Organic matter is that which is living or has been alive‚ e.g. wood or coal. Inorganic matter is that which is not living and never has been alive‚ e.g. water or iron. Inorganic substances can be built up into organic compounds by living organisms. All living matter is made up of small units called cells. Some organisms‚ such as bacteria‚ consist of one single cell; others‚ like human beings‚ consist of many hundreds of millions of cells‚ all functioning together

Pemphigus Vulgaris Pemphigus Vulgaris is an autoimmune disorder in which there is blistering of the skin. The prefix phemphix comes from the greek work meaning “bubble”. This disorder affects the epithelial and mucous membranes. Although unlikely‚ certain medications can cause this disorder. These medications include: blood pressure medications and chelating agents. This autoimmune disease is especially rare and is limited to older adults to the elderly. A way that you can test for it is by

Ichthyosis Vulgaris Ichthyosis vulgaris is a member of a group of cutaneous disorders of keratinization and appear both clinically and histologically. Ichthyosis vulgaris disrupts this balance either because too many replacement skin cells are produced or because the skin cells do not separate well from the skin surface when it is their time to drop off. The result is that skin cells accumulate into thick flakes that adhere to the body. Ichthyosis vulgaris can be a nuisance‚ but rarely affects overall

concentrations of alcohol on the membrane structure of a beetroot a) Decide what you think will be the effect of alcohol on beetroot cell surface membranes and how this will affect their permeability. Write down your idea as a hypothesis that you can test‚ and support your idea with biological knowledge. Hypothesis “The greater the concentration of the alcohol the more red pigments (betalains) move into the solution.” Biological knowledge: The exposure of the beetroot cell membrane to alcohol makes it

This paper is going to explore acne vulgaris‚ commonly referred to as acne. Acne is a skin disease‚ caused by changes in the pilosebaceous units (skin structures consisting of a hair follicle and its associated sebaceous gland). Severe acne is inflammatory‚ but acne can also manifest in noninflammatory forms. Acne lesions are commonly referred to as pimples‚ spots‚ or zits. Acne is most common during adolescence‚ affecting more than 85% of teenagers‚ and frequently continues into adulthood. For

leaky blood vessel network irrigates solid tumors. In this context‚ vascular permeability drives tumor-induced angiogenesis‚ blood flow disturbances‚ inflammatory cell infiltration‚ and tumor cell extravasation. This can directly restrain the efficacy of conventional therapies by limiting intravenous drug delivery. Indeed‚ for more effective anti-angiogenic therapies‚

Investigate factors affecting cell membrane permeability in beetroot. Research Question: How does variation in temperature affect the permeability of cell membranes? Background Information: In this investigation I will want to identify how variations in temperature effect the permeability through the use of a beetroot. I predict that as the temperature of the water increases so will the dispersion of the pigment. Independent Variable: The temperature of water will be increased in increments of 10oC

Title L6 – Soil Permeability – Constant Head Test Introduction Permeability is measured in term of water flow through the soil in a given time. The soil permeability is a very important factor to study the behavior of soil in its natural condition with respect to water flow. The size of pore space and interconnectivity of the spaces help determine permeability‚ so shape and arrangement of grains play a role. Often the term hydraulic conductivity is used when discussing groundwater properties
