Which of the following are chemoreceptors? hair cells in the cochlea receptors in the aortic and carotid bodies baroreceptors in
Mrac [35]

Answer:

The receptors in the aortic and carotid bodies are chemoreceptors.

Explanation:

Chemoreceptors are specialized cells that are responsible for detecting and converting chemical signals into biological signals, to relay that information to the brain, where they will finally be interpreted. Among them we find the peripheral chemoreceptors, which are the aortic bodies, located along the wall of the aortic arch and innervated by the vagus nerve, and the carotid bodies, located in the neck. . Carotid bodies are stimulated by variations in the concentration of oxygen and carbon dioxide in the blood, as well as variations in blood pH. When the pH decreases the CO2 increases and the oxygen decreases, they activate the chemoreceptors to increase breathing.

How are the Kissimmee River, Lake Okeechobee, and the Everglades related?
Taya2010 [7]
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.
