Effects of water pollution. The water pollution is very harmful to humans‚ animals and water life. The effects can be catastrophic‚ depending on the kind of chemicals‚ concentrations of the pollutants and where there are polluted. Below‚ we shall see a summary of the effects of water pollution. The effects of water pollution are varied and depend on what chemicals are dumped and in what locations. Many water bodies near urban areas (cities and towns) are highly polluted. This is the result

Biology Investigation Aim: to investigate the effects of light and gravity on the growth of sunflower seeds. Background Info: Tropism is directional movement in response to a directional stimulus eg light or gravity. Plants are not able to relocate if they happen to start growing where conditions are nor perfect but they can alter their growth towards more favorable conditions. Plants respond to light (phototropism) where the stems grow towards the light and the roots grow away from

Bioassay of Radish Seeds Bioassay is a type of scientific experiment used in the development of new drugs and monitoring pollutants. It estimates the potency of a substance‚ by testing its effect on living matter. In other words‚ it determines how much of the substance is needed to poison an individual‚ without testing it on any humans or animals. From here the TC50 of the substance can be adjusted for dealing with humans and animals over plants. In this lab we attempted to find the potency of

1 October 2010 Salt Water Pool Systems vs. Liquid Chlorine Pool Systems I currently utilize a salt water pool system called an Aqua Rite System. If you’re in the market for a pool‚ it can be a bit overwhelming to choose a type of system that is right for you. The salt water pool vs. chlorine pool battle has been raging over the last decade‚ and today‚ many home owners are building these systems right from the start or converting their old chlorine pools into a salt pool. But what is the real

During the Toxicity of Morton Salt on Radish Seeds experiment‚ we measured the levels of iodized Morton Salt to the growth rate of radish seeds. Each six packets had ten radish seeds with different level of iodized salt solution. The packet with no iodized salt solution grew the longest in a period of days‚ compared to the other packets that had iodized salt. Solutions 100% and 10% had no growth progress within the past five days. As for solutions 1%‚ .1%‚ and .01% grew‚ yet not as much nor fast

increase by adding table salt. The problem it is trying to explain is‚ how does table salt affect the boiling temperature of water? does it increase or decrease? or does it stay the same? Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess” about what will happen in the experiment. What hypothesis can you generate about the effect of adding salt to water? Adding table salt to boiling water will cause the water to boil at a higher temperature

Poppy Seed in daily life (Kas Kas) Kas-kas or it’s scientific name Semen Papaveris also known as Opium Poppy in English‚ is an erect annual herb‚ growing up to a meter and a half in height with large hairless‚ almost grayish-green‚ serrated leaves. Poppy seed‚ tiny dried seed of the opium poppy‚ used as food‚ food flavouring‚ and the source of poppy-seed oil. Poppy seeds have no narcotic properties‚ because the fluid contained in the bud that becomes opium is present only before the seeds are fully

Abstract Moringa seeds are known to contain an antimicrobial substance‚ which gets rid of microorganisms that suppresses growth. This investigatory project aims to prove that Moringa seeds can be used to purify contaminated water. The benefits of this investigatory project is that the purified water may be used in our everyday lives‚ may help in the preservation of water‚ fewer expenses would occur and adds knowledge towards the purification of water. In this experiment‚ Moringa seeds‚ a mortar‚ a clean

The Effect of Salt Concentration on Osmosis in Potato Cells We should first explain what Osmosis is. It’s a passage of water from a region of high water concentration through membrane to a region of low water. Semi membrane is a very thin layer of material‚ which allows some things to pass through them but prevent other things from passing through. The cells allow small molecules like Oxygen‚ water‚ Carbon Dioxide‚ Ammonia. But will not allow larger molecules like Sucrose‚ Starch‚ or protein‚ etc

The dandelion population will probably grow. Eventually‚ dandelions might take over the lawn. 3a. A population grows exponentially when it has all of the resources it needs and disease and predation do not occur. 3b. Exponential growth shows a “J shaped” curve because with each generation‚ the number
