That was fast: The influence of light intensity on the growth and development of Wisconsin Fast Plants Introduction It is common knowledge that plants need light to grow and develop. This is done by the conversion of light energy into usable sugars during photosynthesis. Light absorbing molecules‚ known as pigments‚ absorb only specific wavelengths of visible light‚ mostly blue and red wavelengths (1). Whatever wavelength isn’t absorbed is reflected and the reflection is the color of plant we

A study of the osmoregulatory capabilities in Nereis virens and Phascolopsis gouldi: osmoregulators vs. osmoconformers Introduction Water is essential for life as we know it on this planet‚ and according to Campbell et al. (1999)‚ water is the major constituent of cells. Reactions vital to life occur under aqueous conditions in the body and cells of all organisms‚ and the concentrations of reactants necessary for these reactions depend upon the amount of water present (Pough et al. 2004)

separate water into hydrogen and oxygen and then they combine hydrogen and carbon dioxide to make sugars. 2. What happens to food energy during photosynthesis? During cellular respiration? In Photosynthesis light energy along with carbon dioxide are used to make molecules or (food energy). In Cellular Respiration food energy is broken down to form ATP. 3. Why is photosynthesis important to you? Photosynthesis is important because plants‚ bacteria‚ and small animals use photosynthesis

experiment was to determine the effect of temperature on the rate of movement of Porcellio scaber. Our prediction was that P. scaber would have faster rates of movement in hotter temperatures. We expected this response as P. scaber is an ectotherm. Hence‚ its body temperature is directly determined by the temperature of its environment (Mellanby 1939). Løkke and van Gestel (1998) stated that the rate of the metabolism is controlled by the environmental temperature for ectotherms. As seen by Wieser

Optic nerve sheath diameter (ONSD) The anatomy of the optic nerve sheath : The intraorbital section of the optic nerve extends from the globe‚ where it inserts medially‚ to the optic canal located in the lesser wing of the sphenoid bone. It is encased by a meningeal sheath consisting of dura mater‚ arachnoid mater and pia mater. Cerebrospinal fluid is contained in the trabeculated subarachnoid space and is continuously and slowly filtered. As a result the optic nerve sheath is in direct

for cellular respiration and photosynthesis are almost exact opposites. Photosynthesis is anabolic; it builds up glucose‚ or sugar‚ from light energy‚ water and carbon dioxide. The chemical equation for photosynthesis is: 6CO2 + 6H2O + Light Energy C6H12O6 + 6O2. Cellular respiration‚ on the other hand‚ is catabolic. It breaks down glucose to form carbon dioxide and water. The chemical equation for cellular respiration is: C6H12O6 + 6O2 6CO2 + 6H2O + 38 ATP. Cellular respiration and photosynthesis

PURPOSE What sugar will get the most rise out of yeast‚ so you can get the best bread or baked goods possible. Sugar when mixed with yeast and water will produce carbon dioxide. The carbon dioxide from the yeast sugar and warm water will make the balloon on top of the water bottle blow up. I hypothesize that brown sugar will make the balloon blow up the most HYPOTHESIS If I were to mix brown sugar‚ with yeast‚ and warm water together it should have a different reaction as opposed to other sugars
