rate of how fast and slow contractile vacuole contracts in the Tetrahymena depends on what osmosis pressure it is in. The tetrahymena fills up with water and then contracts right before it bursts. Osmosis occurred in this experiment which affected the rate at which contractile vacuole contracts in the Tetrahymena. In a hypertonic solution, such as 500mM NaCI, water is already leaving the cell due to osmosis, a type of diffusion of water going from a high concentration to a low concentration or…
Results Table 1 showed that oral administration of Diclofenac sodium at 150mg/kg.b.w. resulted in a significant increase in renal tumor necroses factor -α (TNF-α), nitric oxide (NO) and thiobarbaturic acid reactive substances (TBARS) compared to the normal control group (p< 0.01). Rat receiving extract of any of the two doses of cranberry extract used in this study (75 and 150mg/kg.b.w.) showed a significant decrease in renal TNF-α, NO and TBARS compared to the group that received Diclofenac…
3.5. Effect of surfactant Span80/Span85 (3:1) on Ni (II) extraction Span80/Span85 are playing an important parameter and determine to appropriate surfactants can be obtained through the stability of emulsion liquid membrane for Ni(II) extraction. Span 80/Span85 as nonionic surfactants. Figure (9).The study of the efficiency of the highest extractants and reached to 98.7% after studying the surfactant concentration of span 80/span85 (3:1), the surfactant ratio an important in extraction of Ni…
Some physical and chemical properties of watermelon rind and sharlyn melon peel powders Proximate composition WAC, OAC and antioxidant activity of watermelon rind and sharlyn melon peel powders Data in Table 2 showed that the watermelon rind powder had higher moisture, ash, fat, protein and carbohydrates (10.61%, 13.09%, 2.44%, 11.17% and 56.02%, respectively) as compared to sharlyn melon peel powder. On the other hand, the sharlyn melon peels had higher content of crud fiber (29.59%) as…
Abstract In this study, a CO2-respensive GM-AD-HA hydrogel derived from electrostatics crosslinks and supramolecular bond will be produced and studied about its mechanical properties and physiological performance. It is expected to have application in restoring cartilage and controllable delivery of Epirubicin Background of research Hydrogels have crosslinked microstructure and can swell up in water without resolving. Their soft and rubbery nature minimizes inflammatory reactions of the…
Cutin,Waxes and Suberin Definition: There are lipophilic barriers in all plants that prevent the water loss and manage the movement of, solutes, and gases.Cutin waxes and suberin are these lipophilic barriers. (1) (2) Introduction: Cuticle is the protective and waterproofing covering that covers the plant organs and prevent water loss and entry of microorganism.Cuticle structural component is cutin. Suberin also act as a fence for the pressure from the environment and cutting and is formed…
4.5.3 Texture Acceptability of Mushroom Soup In term of texture, the acceptance of particle in soups was determined (Table 4.3). Generally, soup prepared from freeze dried powders had higher scores for acceptability of 4.47 ± 1.10 than oven dried and vacuum dried powder that varies between 3.80± 1.06 and 4.47± 1.43. However, there was no significant difference (p> 0.05) among the soups prepared with fresh mushroom and powders in the respect of texture. The lower texture acceptability of oven…
1959702695 Osmosis is a type of facilitated diffusion where water molecules move from high concentrations of water to low concentrations of water through a selectively permeable membrane. Osmosis is a way for water molecules to create equilibrium between a cell and its environment. For example, if the cell is a hypotonic solution and its environment is a hypertonic solution, then water will naturally diffuse to its environment to create equilibrium. The guiding question for this experiment was,…
Doherty Biology Lab Report 09/29/16 The change in concentration of sucrose affect the change in mass of potatoes cores. Introduction This experiment was focus about osmosis. If solute cannot readily move across the membrane, water will move and tend to balance the solute concentration. In this process, called osmosis, water moves across a membrane from the hypotonic compartment (with a lower concentration) into the hypertonic compartment (with a higher concentration). In hypotonic…
During my dialysis experience I found it to be very informative and interesting. We were not allowed to touch the patients or help with any care but the staff was interactive and explained was they were doing. The staff also was able to provided scenarios of different complications that happened and how they 'd respond. By the end of the first day I was able to see what the caregiver would due if a patient had muscle cramps, was short of breath and had chest pain. The first day I mostly…
