Materials & Procedures: Material: In this experiment‚ the we used: tape‚ 2 water bottles‚ scissors‚ 6 different cotton balls‚ 1 chamber‚ about 20 fruit flies‚ water‚ lime water‚ banana‚ vanilla extract‚ and ammonia. Procedure: Cut the bottom ends off of two water bottles‚ and tape them together. I labeled each cap with letter “A” and “B.” I then inserted the fruit flies in through one end. For each new substance‚ we dropped a few drops of it onto the

the distribution is roughly 71% hydrogen‚ 24% helium and 5% other elements by mass. The atmosphere contains trace amounts of methane‚ water vapor‚ ammonia‚ and silicon-based compounds. There are also traces of carbon‚ ethane‚ hydrogen sulfide‚ neon‚ oxygen‚ phosphine‚ and sulfur. The outermost layer of the atmosphere contains crystals of frozen ammonia.[17][18] Through infrared and ultraviolet measurements‚ trace amounts of benzene and other hydrocarbons have also been found.[19] The atmospheric

materials include wood shavings‚ sawdust‚ peanut hulls‚ shredded sugar cane‚ straw‚ and other dry‚ absorbent‚ low-cost organic materials. Sand is also occasionally used as bedding. The bedding materials help absorb moisture‚ limiting the production of ammonia and harmful pathogens. The materials used for bedding can also have a significant impact on carcass quality and bird performance.[1] There are specific practices that must be followed to properly maintain the litter and maximize the health and productivity

Separating Substances: Identifying Food Dyes with TLC Background The color of food is an integral part of our culture and enjoyment of life. Who would deny the mouth-watering appeal of a deep-pink strawberry ice cream on a hot summer’s day or a golden Thanksgiving turkey garnished with fresh green parsley? Even early civilizations such as the Romans recognized that people "eat with their eyes" as well as their palates. Saffron and other spices were often used to provide a rich yellow color

This composes the upper 25% of the planet. Next‚ the hydrogen thins out into the gaseous atmosphere which is 1000 km (620 miles) deep. It is composed mainly of hydrogen and helium with trace amounts of methane‚ water‚ ammonia‚ and hydrogen sulfide. Some scientists believe that there are also polysulphur compounds and phosphine which lend their colors to the clouds. Jupiter also has a faint ring system. It is comprised of one main ring‚ with fuzzier "gossamer" rings farther

Chlorine in the pool reacts with organic matter‚ such as urine‚ sweat‚ and saliva‚ to produce disinfectant by products (chloramines). The main chloramines found in pools is nitrogen trichloride (NH3 + 3 HOCl → NCl3 + 3 H2O) ammonia (NH3). Nitrogen trichloride is the most vaporous chloramine and is easily released into the air‚ this gas causes reactions experienced by some swimmers. Recent studies suggest that long-time exposure to these chloramine compounds can cause the skin

The natural gas industry in Trinidad and Tobago began with the discovery of gas on land at Mahaica in 1955 by Dominion Oil‚ however the first major natural gas discovery (One Trillion Cubic Feet (Tcf)) was off the East coast of Trinidad by Amoco in 1968 in the Teak offshore field. This was followed up in 1973 by a 2 Tcf find in the South East Galeota acreage. There was however production and utilization of gas before this date. Although the dates referred to mark the first large finds of natural
