Comparison of Studies: Effects of Fluoride concentration in Drinking Water

- Since the implementation of artificially introducing fluoride into water, a great amount of resistance has taken place. Many people claim that fluoridating community water sources can cause not only dental fluorosis, but a multitude of adverse systemic conditions. This perception has led to many political battles on the subject. The problems associated with fluoride ingestion tend to present when concentrations are higher that generally accepted. In communities with natural high fluoride concentrations, adverse effects have range from dental and skeletal fluorosis to decreased birth rates, increased kidney stones, impaired thyroid function, and lower intelligence (Chen, 2013, p....   [tags: fluoridation, community water, dental caries]

The Effect of Water Concentration on the Mass of Potato Tissue

- The Effect of Water Concentration on the Mass of Potato Tissue Aim: The aim of this investigation is to discover the effect of water concentration on the mass of potato tissue, and also to investigate the movement of osmosis through potato tissue. Scientific Knowledge: When a substance such as a sugar dissolves in water, the sugar molecules attract some of the water molecules and stop them moving freely. This, in effect, reduces the concentration of water molecules. Water Potential: The water potential of a solution is a measure of whether it is likely to lose or gain water molecules from another solution....   [tags: Lab Report]

Investigating the Concentration of Water in Potato Cells Through Osmosis

- Investigating the Concentration of Water in Potato Cells Through Osmosis Introduction Osmosis is defined as the movement of water molecules from an area of high water concentration to an area of low water concentration, across a semi-permeable membrane. I will be experimenting to find the concentration of water in potato cells through Osmosis. Aim The aim of this investigation is to analyze and experiment in order to study the concentration of water in potato cells through Osmosis....   [tags: Biology Lab Report]

The Effect of Changing the Concentration of Sucrose on the Movement of Water into a Potato

- The Effect of Changing the Concentration of Sucrose on the Movement of Water into a Potato Introduction Aim 1. To use different concentrations of sucrose solution to determine the internal concentration of the potato. 2. To use different concentrations of a solution more dilute than the internal concentration of the potato to find out what the effects of different sugar concentrations have on the movement of water into the potato. Theory ====== Osmosis is the movement of water from a dilute solution to a more concentrated solution, through a partially permeable membrane, until the concentrations are equal....   [tags: Biology Lab Report]

The Human Body : A Miracle Of Ways

- The human body works in a miracle of ways. Every minimal action makes dramatic differences or is significant to the continual task of the human body. One thing ends up leading to another, much like a domino effect, therefore every little detail plays an enormous role. In the case of diffusion and osmosis, both are two important figures that deeply contribute to the successful progress of the body through equilibrium between two concentrations. Mutually, the factors assist the human body in maintaining homeostasis through similar aspects....   [tags: Osmosis, Concentration, Diffusion, Water]

The Effect of Concentration of Water in a Saline Solution On the Process of Osmosis in a Potato

- The Effect of Concentration of Water in a Saline Solution On the Process of Osmosis in a Potato Aim The aim of this experiment is to find out what effect the concentration of water in a saline solution has on the process of osmosis in a potato. Osmosis is a specialised case of diffusion involving water diffusing through a semi-permeable membrane. Semi-permeable membranes are very thin layers of material that allow some things to pass through them but prevent other things from passing through....   [tags: Lab Report]

An Investigation to Show How Water Temperature and Alcohol Concentration Affect Membrane Permeability

- An Investigation to Show How Water Temperature and Alcohol Concentration Affect Membrane Permeability Aim The aim of the experiment is to show the cell’s membrane permeability is affected by being placed into different temperatures of water. Also the effect of placing beetroot in to different concentrations of alcohol. Beetroot cells contain a red sap, which leaks out of the cells if their membranes are damaged or altered. Cell membranes are made up of a bilayer of phospholipids, which also contains proteins....   [tags: Biology Lab Report]

What Different Groups Who Drank Bottles Of Fluid For Each Kg Of Body Weight

- 1. Compare the different groups who drank 7.5ml of fluid for each kg of body weight. Which group had the highest average urine production rate. Why. o The group with the highest average urine production rate of 7.5 mL of fluid for each kg of body weight was the diet caffeine free group. Diet caffeine free uses NutraSweet instead of glucose as the sweetening agent. NutraSweet causes high filtrate osmolality, which decreases reabsorption and moves water from out of the tissue into the urine, increasing urine output....   [tags: Concentration, Mass, Solution, Water]
