Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle

SOLAR POWER IN TODAYS WORLD JEROME T. GARDNER COLUMBIA SOUTHERN UNIVERSITY ABSTRACT Since first discovered in the 1860s‚ the concept of storing energy from the sun to use as a source of power has been studied and pursued by many programs. Either using solar collectors or photovoltaic cells‚ the methods of using solar power are becoming more efficient and cost-effective. Solar technology is currently being used by homes and businesses‚ but is still too expensive and risky for many residents. Researchers

LED (light emitting diode) lights are programmed to deliver the wavelengths of light that plants prefer to create optimum growing conditions Plants would grow along the building’s south-facing sides to get maximum sunlight exposure. Solar panels that surround the building also provide extra power. Wind turbines which are installed at the top of the building will generate electricity to help power equipment.

However‚ as the human evolved and lost a significant amount body hair‚ the skin‚ the largest organ of the body‚ would become exposed to the strong ultraviolet rays of the sun. Ultraviolet B‚ a specific type of ultraviolet light‚ is beneficial as it effectively converts our cholesterol into Vitamin D‚ which the body cannot simply live without. However‚ too much sunlight exposure and harmful effects quickly outnumber the beneficial

where energy from sunlight is captures in Photosystem 2 and then 1‚ the electrons generated in Photosystem 1 then moves along the electron transport chain. The moving of electrons causes a hydrogen ion gradient that is used in the final step to produce ATP‚ by the ATP Synthase. The equation for this reaction is 6CO2 + 6H2O C6H12O6+6O2 or‚ carbon dioxide +water sugars + oxygen . This reaction takes place on the thylakoid membrane of the chloroplast and uses energy from sunlight to produce compounds

The European Tree Frog‚ is a very common species of tree frog that resides in the terrestrial (forested) areas of Europe and West Asia. Also known as Hyla arborea‚ this frog belongs to the class Amphibia. The European Tree Frog utilizes trees and large plants as habitats. Due to this‚ the frog has round‚ adhesive toes that help enable climbing. This frog is genuinely amazing. All living things have structures‚ and each of those structures has a specific function. A structure is basically a part of

The first step in the chain invovles the producers‚ or autotrophs like the phytoplankton. These producers convert sunlight into organic compounds through photosynthesis. The herbivorous consumers such as the beetle larvae (invertebrate grazers) feed on the algae and will be later consumed by

The Sun (Star of the Family) Planet word comes from Greek ‚which means „wandering star“. Sun is the heaviest among Solar System. If we take total mass of whole Solar System‚ the Sun would be 99.86% of the total. Sun is a ball of hot‚burning gases. Sun is the nearest star to the Earth. Sun is the source of all energy for life on Earth. On the Sun’s surface‚ there are dark patches known as sunspots. These are patches of gas that looks dark since they are cooler than their surroundings. The light

I. INTRODUCTION Today‚ every country draws its energy needs from a variety of sources. We broadly classified this source as conventional and non conventional. 1.1] CONVENTIONAL SOURCES 1) Fossil fuels‚ 2) Hydroelectric power‚ 3) Nuclear fission‚ 1.2] NON-CONVENTIONAL SOURCES 1) Solar energy‚ 2) Wind energy‚ 3) Bio mass and bio gas‚ 4) Ocean thermal energy‚ 5) Tidal energy‚ 6) Geothermal energy. Energy is the prime mover of economic growth and is vital to the survival of a modern economy
