determine how different concentrations of salt water effect plants. The test that will be performed will prove which concentration will have the worst effect. The hypothesis is that by measuring the plants growth each day‚ the largest concentration of salt will harm the plants the most. First‚ the plants were purchased and the water was prepared with the salt concentrations. Second‚ the plants were watered each day with the different concentrations of salt. Third‚ the plants’ growth were observed

Plant hormones are specialized chemical substances produced by plants. They are the main internal factors controlling growth and development. Hormones are produced in one part of a plant and transported to others‚ where they are effective in very small amounts. Depending on the target tissue‚ a given hormone may have different effects. Plant hormones play an integral role in controlling the growth and development of plants. A plant hormone is generally described as an organic compound synthesized

Christine Otieno Estimating Osmolarity of plant Cells(potato and celery)by percentage change in weight Using different sucrose concentrations Introduction The purpose of this experiment was to estimate Osmolality of plants cells i.e. Potato and celery by converting the observed change of weight in different sucrose concentrations. The hypothesis assumes that the solute concentration of the plant samples would be indirectly proportional to the weight; there would be decrease

Neale Hurston. In the essay How It Feels to Be Colored Me‚ Zora explores her own sense of identity through a series of striking metaphors. After realizing that she is of color‚ Hurston never really places a significant emphasis on the racial inequalities that exist in America. “At certain times I have no race‚ I am me.” Zora Neale Hurston did not have any separate feelings about being an American and colored. “But I am not tragically colored. There is no great sorrow dammed up in my soul‚

Effects of Cold Weather on Incandescent Light Bulbs Abstract Cold weather hasn’t previously been known to have much of an effect on incandescent light bulbs. But colder temperatures do make electricity flow more smoothly and easily. In this experiment‚ it was concluded that cold weather‚ does in fact‚ affect an incandescent light bulb in a circuit. The tests in this experiment showed that when a light bulb circuit is placed in cold temperatures‚ the incandescent light bulb seems to glow brighter

A2 Practical Investigations Title: The effect of Temperature on the growth of Aspergillus oryzae Develop a Hypothesis This particular investigation is to discover how a range of temperatures effects the growth rate of the fungi Aspergillus oryzae. Most fungi’s tend to survive within the temperature range of 5-35oC‚ with the optimum depending on their normal environmental temperature. The fungi Aspergillus oryzae is heterotrophic which means they taken in their food from dead organic matter and cannot

example‚ is a well-balanced nitrogen-rich quick-reacting liquid fertilizer. It contains nitrogen‚ potassium and phosphorus and other nutrients depending on the diet. The health risks associated with use of human urine in plant production are generally low‚ that is why it’s an adequate plant fertilizer. On another note‚ Indian tree (Polyalthia longifolia) is a small-to-medium-sized evergreen tree growing up to 15 meters. Its leaves are long‚ narrow and oblanceolate‚ dark green‚ glossy and have wavy margins
