An Investigation Into The Effect Of PH On The Activity Of Potato Tissue Catalase Aim The aim of my investigation is to see how pH affects the activity of potato tissue catalase‚ during the decomposition of hydrogen peroxide to produce water and oxygen. Catalase + 2H2O2 Catalase + 2H2O +O2 Catalase + Hydrogen Peroxide Catalase + Water + Oxygen Independent Variable The independent variable in this investigation is pH. Each individual enzyme has it’s own pH characteristic

blood plasma osmolarity. Since non-invasive methods were preferred the volume and concentration of urine was used in place of drawing blood. The results that we our anticipating are that ADH levels in the group of subjects that ingested the 6 gm. Of NaCl would increase over time in response to the increased osmolarity of the blood from all of the salt. Urine output would decrease and eventually the body would stabilize. Purpose: In this experiment‚ renal regulation of osmolarity will be demonstrated

Epithelial tissue protects your body from moisture loss‚ bacteria‚ and internal injury. There are two kinds of epithelial tissues: Covering and lining epithelium covers or lines almost all of your internal and external body surfaces; for example‚ the outermost layer of your skin and other organs‚ and the internal surface lining of your lymph vessels and digestive tract. Glandular epithelium secretes hormones or other products such as stomach acid‚ sweat‚ saliva‚ and milk. Connective tissue generally

Estimating Osmolarity by Change in Weight By: Sondus Kahil 27 February 2012 TA- Ashley Hintz Biology 200A-section 002 Abstract: My group and I conducted the experiment that estimates osmolarity by change in weight of potato tubers‚ this was conducted in order to explore the process of diffusion and osmosis and more importantly to investigate the question of “Does different concentrations of sucrose solutions have an effect on the final weight for the potato

The potato is a starchy‚ tuberous crop from the perennial Solanum tuberosum of the Solanaceae family (also known as the nightshades). The word may refer to the plant itself as well as the edible tuber. In the region of the Andes‚ there are some other closely related cultivated potato species. Potatoes were introduced outside the Andes region four centuries ago‚ and have become an integral part of much of the world’s cuisine. It is the world’s fourth-largest food crop‚ following rice‚ wheat and maize

Research Project: Potato The potato originated in the South American Andes‚ but its heartland of wild genetic diversity reaches from Venezuela‚ Colombia‚ Ecuador‚ Peru‚ Bolivia‚ Argentina‚ Chile‚ Uruguay‚ Paraguay‚ southern Brazil‚ northward into Central America‚ Mexico‚ and the southwestern United States. Potato was first cultivated between 3 and 7 thousand years ago‚ some scientists believe they may have grown wild in the region as long as 13‚000 years ago. Potato is the third most important
