How Does Salinity Effect Osmosis in Plant Cells? Introduction Osmosis is a type of diffusion but is the movement of water molecules in and out of the cells from a high concentration to low concentration through a semi permeable membrane. The aim of the experiment is to investigate the effect the salinity of solutions has on the process of osmosis and net weight gain/ loss by potato cells. This would be done by using similar size potato cubes and covering them with different concentrations of saline

Soil‚ which is one of the most important natural resources‚ is often less heeded. The importance of soil conservation is relatively less talked about as compared to the conservation of water and other natural resources. The almost-omnipresent soil is mostly taken for granted. Its omnipresence is ironically the reason behind us‚ human beings‚ taking it for a ride. We rarely even think of it as a natural resource that needs to be conserved‚ a part of the natural wealth that needs to be preserved.

excess carbon dioxide in the atmosphere that we don’t see or feel because its effects are happening underwater. When carbon dioxide is absorbed by seawater a chemical reaction occurs that reduces the seawaters pH‚ carbonate ion concentration‚ and saturation states of biologically significant calcium carbonate minerals. It decreases the pH of seawater‚ meaning it increases the seawater’s acidity. Over the past 250 years‚ ocean acidity has increased by 30 percent. At least one-quarter of the carbon

Shallow-water Acoustics and Relevant Physics By: Elizabeth Fortlage Underwater Acoustics is a complex phenomenon. Leonardo da Vinci simplified the concept in 1940‚ two years before Columbus discovered America‚ by saying “If you can cause your ship to stop and place the head of a long tube in the water and place the outer extremity to your ear‚ you will hear ships at a great distance from you.” (5‚ p.2) There are many factors that contribute to the complexity of underwater acoustics and sonar

potentially hazardous chemicals. In addition‚ the impacts of pH‚ salinity‚ sodium‚ phoshphorus and sulphur are not addressed in advertising. Moreover‚ most product labels do not state the ingredients meaning that purchasers can never be sure what is actually in the product. Considering these issues‚ this project has been set out to analyse the effect of the greywater irrigation by addressing several factors such as the pH‚ salinity‚ electrical conductivity‚ hydraulic conductivity‚ surface tension

“What’s that Awful Smell”? - Bromine There are 118 known elements to man‚ and each of them differ in its own way. They vary from weight‚ structure‚ color‚ and much more‚ but many of them are similar to others and can be grouped accordingly. One element that varies drastically from others is one whose stench is so horrible‚ that the original name of the element was changed from muride to bromos‚ which means “stench” in Greek. Thus‚ bromine was named. Like many other known elements‚ bromine was discovered

of brine shrimp per jar whilst keeping algae concentration and volume of seawater in each jar constant. There will be three groups of jars with each group containing 3 jars each; group 1 will have one brine shrimp‚ group 2 will have two brine shrimps‚ while group 3 will be the control‚ already filled with the required concentration of algae and containing no brine shrimp. Fill the group 1 and 2 jars with 46.68 mL of seawater and 3.32 mL of algae‚ taken from the 25‚000 cells/mL jar of algae. Be sure

In our search for prosperity‚ growth and success‚ we are destroying the system that we as human are completely dependent upon. Population growth‚ water-intensive agriculture and economic development are using water faster than it can be replenished. Our Earth is a place where beauty exists‚ a place where 6.6 billion people and 15 million other species live‚ a place filled with 1.4 cubic kilometers of water. Although 70% of the planet’s surface is blanketed with deep oceans water‚ freshwater only
