Between 1962 and 1971, the United States Army Corps of Engineers (USACE) channeled the Kissimmee River and created a 30-foot deep, 300-foot wide, 56 mile long drainage canal (C-38). This project converted 44% of the floodplain to pasture, draining approximately 31,000 acres of wetlands. Before channelization, the River was a haven for wildlife, including at least 39 species of fish and 38 species of water birds.
Kissimmee River Restoration began in 1992 and has been the most successful ecosystem restoration initiative to date. By re-channelizing the River to replicate its natural paths, birds and other wildlife responded more quickly than anticipated and demonstrated the resiliency of nature. This success has been used all over the world to justify the value of ecosystem restoration. When Kissimmee River Restoration is completed in 2015, more than 40 square miles of the River-floodplain ecosystem will be restored, including almost 20,000 acres of wetlands and 44 miles of historic river channel.
Latitude is not a factor in marine life divisions.
Answer:
A
Explanation:
The pulmonary artery carries de-oxygenated blood from the right ventricle of the heart to the lungs. It is the only artery that carries de-oxygenated blood. This blood is usually from the tissues and has a lot of carbon dioxide from the cellular respiration of cells around the body. The blood is pumped to the lungs to be oxygenated and the carbon dioxide expelled.
Answer:
See below.
Explanation:
A star's energy comes from the combining of light elements into heavier elements in a process known as fusion, or "nuclear burning". It is generally believed that most of the elements in the universe heavier than helium are created, or synthesized, in stars when lighter nuclei fuse to make heavier nuclei. The process is called nucleosynthesis.
Our Sun is currently burning, or fusing, hydrogen to helium. This is the process that occurs during most of a star's lifetime. After the hydrogen in the star's core is exhausted, the star can burn helium to form progressively heavier elements, carbon and oxygen and so on, until iron and nickel are formed. Up to this point the process releases energy. <u>The formation of elements heavier than iron and nickel requires the input of energy. </u>Supernova explosions result when the cores of massive stars have exhausted their fuel supplies and burned everything into iron and nickel. The nuclei with mass heavier than nickel are thought to be formed during these explosions.
24.) C - a change in DNA coding can lead to a change in the protein that is produced, which changes structure, and therefore, function.
28.) C - recombinant DNA is artificial, and the other examples can occur naturally
29.) B - if DNA enters and successfully is produced within a plant cell, but is not originally from the plant cell, then the cell has been transformed.
