Title: The effect of salt concentration on osmosis in potato. Introduction: 1. The purpose of doing this lab is to observe the effects of various solute concentrations on osmosis in a potato. 2. During osmosis‚ water moves from the side of the membrane where they are most concentrated to the side where they are less concentrated. If the concentration is equal on both sides‚ there will be no movement. 3. I hypothesize that the mass of the potato will decrease as the salt in the solution

is the largest increasing factor in our world. This factor is the cause of many events in our world. Poverty hunger and war are just some of the immediate effects of increasing population. Among these extreme causes the less immediate events will be seen with air pollution‚ land degradation‚ which is the effect that’ll have the longest term effect on the world. But how can these events are avoided? Is there any hope of stopping this from occurring any further? The largest‚ most identified reason for

LABORATORY EXERCISE 8-A: Preparation of Bacterial Smear and Simple Staining I. INTRODUCTION Bacterial smears are prepared for the purpose of viewing microorganisms under the microscope. Visualization of microorganisms in the living state is very difficult‚ not just because they are minute‚ but because they are transparent and almost colorless when suspended in an aqueous medium. A bacterial smear is a dried preparation of bacterial cells on a glass slide. Smears may be made from a dry culture

Introduction Over the course of several weeks‚ myself and my fellow classmates have been researching and conducting an experiment that focuses on the effect of ascorbate peroxidase (a.p) as well as salt stress at different levels of concentrations on Abelmoschus esculentus (okra). Okra is a plant that is composed of 87.1% of water. In addition to being made mostly of water this highly nutritious vegetable is also composed of 0.2% of fat‚ 9.7% of carbohydrate‚ 2.2 % protein‚ 1.0 % fiber‚ and 0

Salt and Its Uses As we know‚ salt is the most useful resource found on earth. In Ancient Rome‚ salt was used as part of the salary to the soldiers. From this‚ we can see that salt was as valuable as gold in the past. In our daily life‚ besides making nutritious food more palatable‚ salt is very useful in making bakery products‚ canned and frozen foods. Salt is a good preservative that retards the growth of micro-organisms to make food storage possible for a long period of timie

Effects of Rapid Population Growth While population growth is at times a beneficial thing for a species‚ there are many factors that define when growth becomes detrimental. When population growth becomes "rapid" there is a great chance that the counter-productive level has been reached. The most accurate index is the balance between population and sustainability. 1. Rapid Growth o Rapid growth is a quick increase in population. The number concerned when calculating the population is the number

The Effect of Watering on the Plant Growth 1. Problem/Question: Sarah observes the small garden in their house. She ask her mother why are the plants needed water but it has fertilized already. Their plants aren’t grow . So she decided to experiment on what is the effect of watering on plant growth. 2. Observation/Research: She water them every day‚ they have good soil‚ and they’re in the shade. 3. Formulate a Hypothesis: Sarah think plants will grow better if they’re in the sun
