pressure in the maggots’ chamber decreases‚ causing air to be drawn into the chamber‚ and therefore displacing the fluid. This double chambered respirometer‚ allows you to measure the pressure changes‚ due to the presence of a control tube. The rate of oxygen intake is measured by recording the distance the dye moves up the scale. We then calculate the mean and multiply by ?r².

Photosynthesis notes -sunlight brings energy to Earth -the energy in sunlight is packaged in photons -the photosystems in the thylakoid membrane capture photons -pigments in the photosystems have an antenna complex that actually grabs the photons -chlorophyll b captures the photons and transfers the energy to chlorophyll a (the reaction center) -when the reaction center receives the energy it donates an electron -the donated electron will move down the electron transport system (ETS) -ETS

ABSTRACT: By exposing Brassica rapa seedlings to UV-C light‚ the effect of the growth and development of Brassica rapa seedlings was tested. The experimental group of Brassica rapa seedlings was exposed to 254 nm UV-C light for thirty seconds after one week of growth. Throughout the duration of one month‚ the height‚ number of leaves and stem diameter were measured sporadically. After one month‚ the biomass of the seedlings was recorded. A starch analysis test was also performed. According to the

HIIT or high intensity interval training is basically has a succession of intervals of intense and light exercise. Always starts by heating 2-10 minutes. Then followed the dismissal of the interval (from 20 seconds to 2 minutes) intense exercise and light exercise. Number of pairs interval (fast-slow) depends on the fitness exercisers‚ how long it is this kind of training‚ the duration of the interval and the intensity of exercise in "fast" interval. HIIT training is only one of a modification of

needed for photosynthesis. The process of photosynthesis occurs in all plants‚ plants absorb sunlight through the leaves using the chlorophyll pigments in the leaf cells. The carbon dioxide diffuses through the stomata‚ under the leaf. The roots of the plants absorb the water from the soil and then the xylem will transport the water and nutrients upward to the leaves. As well as that the roots also store nutrients and anchor the plant. Plants also need Nitrogen to allow them to photosynthesis. Plants

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

Factors of Channel Intensity Decisions There are eight factors for channel intensity decisions and the first is channel competition to prevent complacency in this a manufacturer has to place its brand or product in different stores. This helps the business to expand its profits‚ and keeps them in competition with other brands. The book tells us how weaker brands may do this by contracting with large retailers such as Wal-Mart in order for their product to be show cased; but this may not always be
