[Type text] [Type text] [Type text] _An experiment on the effect of surface area to volume ratio on the rate of osmosis of Solanum tuberosum L._ BACKGROUND A cell needs to perform diffusion in order to survive. Substances‚ including water‚ ions‚ and molecules that are required for cellular activities‚ can enter and leave cells by a passive process such as diffusion. Diffusion is random movement of molecules in a net direction from a region of higher concentration to a region of lower concentration

The drinking simulation examined the effects of social pressure with alcohol. Students were able to experience different emotions‚ adjust to new social groups‚ and apply lessons to their own lives. Understanding from a point of view that all students are college students‚ we are more likely to get into situations of drugs‚ sex‚ and alcohol. The college campus and dorms along with a group of people who are around the same age‚ predicts our actions in college. In this simulation‚ Dr. Petranek and his

Filtration is commonly the mechanical or physical operation which is used for the separation of solids from fluids (liquids or gases) by interposing a medium through which only the fluid can pass. Oversize solids in the fluid are retained‚ but the separation is not complete; solids will be contaminated with some fluid and filtrate will contain fine particles (depending on the pore size and filter thickness). Filtration is also used to describe some biological processes‚ especially in water treatment and sewage

Urine Specific Gravity Each day an adult excretes between 800ml and 2000mL of urine. This amount varies depending on various conditions that can influence fluid loss and fluid intake. For example‚ the loss of fluid through heavy sweating in hot weather reduces urine amounts. The minimum volume of urine needed to remove body wastes from an adult is about 500mL/day. The specific gravity of urine can be an indicator of disease or disruption in normal metabolism. As you recall from our earlier discussions

How to Adjust Entries for a Trial Balance A trial balance is created by companies at the end of an accounting period. It contains a list of all accounts within an accounting system that have balances. Companies separate the accounts into different categories‚ which include assets‚ liabilities‚ equities‚ revenues and expenses. The accounts are listed in order‚ beginning with assets‚ and each includes a balance that is either a debit or credit. Asset and expense accounts have debit balances‚ while

` Project 3.4.3: The Blood/Urine Connection Introduction Water is obtained from food‚ drink‚ and from reactions that occur in the body. The kidneys process and balance the amount of water that enters your system with the amount that is released. The digestive system helps rid the body of solid wastes‚ but some of the wastes in the blood are the remnants of the digestion of food products. For example‚ when amino acids are broken down by the body‚ ammonia (NH3) is formed. This product is so
