Reverse osmosis

Mycelial discs (5 mm diameter) were inoculated in potato dextrose broth as above and incubated at 28+1°C for 7 days. The mycelial inoculum of M. phaseolina was centrifuged at 5000 rpm for 10 minutes. Supernatant was decanted and pellets were washed and re-suspended in sterile distilled water. At 15th days after sowing, the soil was inoculated in Set-II by drenching the soil near plant roots. On 8th day ten seedlings from three replicates were chosen randomly for measurements of shoot and root…

The materials given were three raw chicken eggs, vinegar, maple syrup, tap water, and table salt. Prior to beginning the experiment, the raw chicken eggs were saturated in vinegar for two days, in order to remove the outer shell. Also before beginning the experiment, the mass of the glass dish was obtained, via a triple beam balance, for measuring/zeroing purposes. On the day of the experiment, the three raw eggs were removed from their vinegar bath and rinsed under a stream of tap water,…

INTRODUCTION In this assignment we are going to elaborate on the role of aqueous humor and vitreous humor in maintaining the pressure of the globe, the structures related to the humor, functions of the humors, origin and also pathology related to them. PHYSIOLOGY OF THE AQUEOUS HUMOR The aqueous humour is a transparent fluid similar to plasma, but containing low protein concentrations. It is secreted from the ciliary epithelium (a structure supporting the lens). It is located in the…

Two experiments were conducted in the span of three days, with the plastic bag membrane experiment taking two days to conduct and the egg shell membrane experiment taking three days. The two experiments took place during the same span of days, with the egg membrane lab carried out first. The materials used during the egg shell membrane experiment include: one white egg, a plastic cup labeled “egg”, vinegar, distilled water, corn syrup, a tape measure, saran wrap, a triple beam balance, a…

How ADH Helps Regulate Water Reabsorption The kidneys are highly specialized organs that regulate water homeostasis in the human body. They are composed of functional units called the nephrons. Within the nephron, the majority of water homeostasis takes place in the collecting duct, as this component is responsible for water excretion (Sands & Layton 2017). The crucial hormone that is released in the collecting duct and is responsible for stimulating water retention is the antidiuretic…

diffusion is known to be osmosis, which is known to be the diffusion of water through a water allowing or permeable membrane. Only water should be able to move through most oftenly. Therefore, the diffusion of one or more other substances along with water should not come in, such as solutes. An everyday example of osmosis is from the result of proned fingers. The bathtub that the person is showering is less concentrated in comparison with your body, thus, it is using osmosis to get into our…

Cholesterol has a unique structure that includes four linked hydrocarbon rings forming the steroid structure. The hydrocarbon tail links to one end of the steroid and a hydroxyl group linked to other end. While the hydroxyl group is able to form hydrogen bonds with nearby carbonyl oxygen of phospholipid. Additionally, cholesterol is an amphipathic macromolecule because it has a water-soluble polar region that dissolves in water, but almost the entire is non-polar which does not dissolves in…

~~~Science Project~~~ Experiment 1: Materials~ 2 eggs Needle Scale Bowl Marker Question? What is the difference between weight and mass, and can two objects that have the same mass be different weights? Hypothesis The difference between weight and mass is that mass is the measurement of how much matter is in an object and it will remain constant regardless of gravity. Weight is how heavy an object is depending on the gravitational pull on the object. Step 1: Zero out the scale. Step 2:…

Instead it depends on the permeability. When using active transport molecules go from a high to a low concentration gradient. There are 3 ways for passive transport which are osmosis, diffusion, and facilitated diffusion. Osmosis is when water moves a selectivity permeable membrane. There are three types of solution of osmosis. One of them is isotonic solution where water crosses the membrane at the same rate. Hypertonic is where it loses water to the surroundings. Hypotonic is where water will…

concentration is placed in one of the model cells then the rate of osmosis will increase was supported by the data in this study. To start with, the tap water without any sucrose concentration (M) started at 4.87g and ended with almost the exact same mass after 60 minutes had passed. On the other hand, when 1.20 M of Sucrose Concentration was emerged in water for 60 minutes and pulled out, its mass went from 6.48g to 9.03g.. Osmosis is the net flow of water through a semipermeable membrane. It…
