Preliminary qualitative chemical tests show the presence of alkaloids, carbohydrates, saponins, steroids, terpenoids, phenolics, coumarins and fixed oil, etc.18 Desorption electrospray ionization was employed for fast and direct ambient detection of the anti-tumor drug, camptothecin, and its derivative, 9-methoxycamptothecin in Nothapodytes nimmoniana J. Graham. Different parts of the plant such as leaves, stems and bark were examined. The…

Light as a Pesticide What is a pesticide? Pesticides are substances which are used for attracting and then destroying or vindicating any kind of pests. It is a biological agent which is used to destroy pests. Pesticides are usually used for keeping pests away from plants. Pesticides are used fight insect-borne diseases and they also help to increase food production. Although pests have numerous benefits they also have few drawbacks such as possible toxicity to humans and other species. What is…

Research Question What is the effect of surface area on volume ratio over rate of diffusion of pigment regarding the agar cube, measure by percentage volume of diffusion through time? Hypothesis The experiment involves the use of agar cubes. If the cells of these cubes desire a great surface area to volume ratio in order to carry out their needs (exchanging materials with the environment, receiving oxygen, getting rid of waste products), the SA:V ratio will be larger. Consequently, the rate of…

Salinity is the concentration of salt that has dissolved in water. It is present in water and in soil. Salinity is a major issue in Australia as it has damaging effects which include damage to infrastructure, agricultural production loss and environmental costs. The Australian soil contains salt naturally, it is salt that has accumulated over time and there are many possibilities such as the evaporation of seas that are inland, parent rocks that are weathered. The salt on the surface is absorbed…

Drug is a substance that is used for diagnosis, cure, treatment, mitigation or prevention of disease. It is either a natural product, pharmaceutical preparation or chemical substance. Anti-inflammatory drugs are used for treating inflammation which is characterized by four cardinal signs: redness, pain, swelling and warmth. Most of anti-inflammatory drugs work by inhibiting prostaglandins secretion. Prostaglandins are the chemicals that responsible for promoting inflammation, fever and pain.…

The fenicol groups of antibiotics are one of the generally utilized medications which are wanted to treat sicknesses relating to respiratory and digestive systems. These days, these gatherings of antibiotics are utilized as a part of veterinary prescription adequately. Fenicol gathering of anti-microbials incorporates a few regularly utilized medications like chloramphenicol and florfenicol. As of late, utilization of florfenicol has been expanded on account of its wellbeing in nature when…

Niemann-Pick disease is a condition that affects many body systems. It has a wide range of symptoms that vary in severity. Niemann-Pick disease is divided into four main types: type A, type B, type C1, and type C2. These types are classified on the basis of genetic cause and the signs and symptoms of the condition. Infants with Niemann-Pick disease type A usually develop an enlarged liver and spleen (hepatosplenomegaly) by age 3 months and fail to gain weight and grow at the expected rate…

Movement of materials from areas of high concentration to areas of low concentration id diffusion. Osmosis is diffusion of water. Tonicity compares the environment inside of a membrane with the outside. When a membrane bound structure has a higher concentration of water on the outside of the membrane than the inside is hypotonic. Hypertonic is when a membrane bound structure has a higher concentration of water on the inside of the membrane than the outside. When something is isotonic the inside…

Question: How does the concentration of salt solution affect the percent change in the mass of potato cells? Hypothesis: If the concentration of salt is increased, then the percent change in the mass of potatoes cells will decrease. Abstract: In this experiment we will be testing how salt concentrations affects potatoes. First, potatoes were peeled and prepped for the experiment; while a salt water solution was being obtained. Potatoes were submerged and left in the solution for two hours, and…

organisms, potatoes are made up of tiny, living units called cells. Each cell is surrounded by a cell membrane assisting in the transportation of molecules as well as protecting and keeping out harmful molecules. (Tucker, 2006) The reason certain potatoes gained mass while some lose over the 24 hour period is solely affected by the relationship between the concentrations of the solute in the cell verse the concentration outside the cell. As discussion in the introduction, the increase of solute…
