.... handle twinning, in order for it to be successful for them. Many agencies see twinning as an economic move upward. The American Breeder Service has made efforts to produce semen as well as embryos with high predicted breeding values available to producers. They have been recorded based on twinning probabilities and ovulation rates. A large amount of work on twinning has also been done by the Meat and Animal Research Center. Since the early eighties, they have located cattle with a high frequency of twinning and been forming a breeding foundation based on this characteristic. “ .....

.... year, 17.6 million American adults suffer from a depressive illness. That is 10% of the population. (Pfizer, Dealing) Depression is a whole-body illness, including mind, mood, body, and thoughts. It effects everything from the way you sleep to the way you feel about yourself. It effects how you react and how you see things. Depressive illnesses often interfere with normal functioning and cause pain and suffering not only to those who have the disorder but also to the ones who care about them.

.... has grown from about 3 billion in 1960, and around 2 billion in 1925. Today it increased by almost 90 million each year, and is likely to reach 10 billion by 2025(Corson 4). The reason we currently have an atmosphere crisis is because of human impact on the gases which make up our atmosphere. Our atmosphere, which is made up of four distinct layers blankets our planet and protects up in many way. One way it protects us if from the harmful rays the sun radiates on our planet. Each layer differs from the others in temperature, density, composition and in the way it absorb .....

.... at 17,500 miles per hour, only to have to move within three inches and two degrees of a quickly moving, very fragile object in space. One small thrust of a poorly aligned engine could cost one of four space-worthy shuttles and the world's first and only long-term space station. Docking was over with soon, and was followed by the cosmonauts of Mir greeting the astronauts of Atlantis. Gifts of flowers, candy and fruit were given by the Americans, who in return, following a Russian tradition, received gifts of bread and salt. Knowing the importance of the mission, the Rus .....

.... the rapid uptake of contaminants by marine organisms to name but a few. Oil spillages either by tankers or offshore ridges cause devistating effects on the local environments. Oil is extremely dense which means it floats on top of the water and can kill fish and birds, ruin beaches but nothing as yet has been invented to deal with this major problem. Dangerous metals such as mercury, arsenic and lead are also dumped into the sea. All of these examples have the ability to kill and damage the environment around it. Agricultural Environments : Unwanted plants or insects .....

.... the deadly radiation. The planet will become a barren rock devoid of all life. Global warming is the predicted result of the greenhouse effect, created by so-called greenhouse gases, such as carbon dioxide and methane, in the atmosphere. The increase in these gases is thought to be caused by industrialization, especially by the use of fossil fuels such as coal and oil. These gases act much like the glass in the greenhouse: They let sunlight in and keep the heat from escaping. As these gases increase in our atmosphere, concern has grown that temperatures will increase around .....

.... species, and soil quality, to determine the best method of pest control. Tactics employed include better tillage to prevent soil erosion and introduction of beneficial insects that eat harmful species. Many pests that are attached to crop residues can be eliminated by plowing them underground. Simple paper or plastic barriers placed around fruit trees deter insects, which can also be attracted to light traps and destroyed. Weeds can be controlled by spreading grass, leaf, or black plastic mulch. Weeds also may be pulled or hoed from the soil. Many biological controls are also .....

.... and add ~ 10 mL of distilled water. Stir the mixture, all the while adding ~ 8 mL of 6M of NaOH to the beaker. Check with litmus paper to ensure that it is slightly basic. Fill the beaker with up to 100 mL mark with distilled water. Heat the solution and allow it to boil for 5 minutes. Prepare a squirt bottle with hot water. Filter the solution and rinse the beaker with the hot water. Rinse the filter cake with hot distilled water. Transfer the filter paper into a clean beaker. Add ~ 10 mL of 3M sulfuric acid to the beaker in order to dissolve the filtrate. Remo .....
