Answer:
Scientists learn how climatic changes during the ice age affected life in this region by analyzing specimens found in these tar pits
Explanation:
La Brea Tar Pits are a group of tar pits in Los Angeles. Many preserved remains of ancient organisms (i.e., fossils) were extracted from the tar, including, among others, Western horses, prehistoric camels, three-toed tapirs, rodent bones, insects, mollusks, wood, plants, etc. The oldest fossils have been dated to be approximately 38,000 years ago by radiometric techniques. Moreover, the Last Glacial Period was the most recent glacial period within the Quaternary glaciation, which encompassed the period between 115,000 to 10,000 years ago. This period (LGP) encompassed the Last Glacial Maximum (LGM), which occurred about 20,000 years ago. In consequence, many of the fossils found in La Brea Tar Pits evidence how the ice age affected life in this region. Moreover, many of the fossil species extracted from the tar are still present today, thereby indicating how these species adapted to fluctuating climatic conditions, whereas certain species couldn't adapt fast enough as the environment changed and therefore they went extinct.

a. predicting weather patterns</span>. Scientific models are used in making predictions. One way to do this is by analyzing big chunks of data from the past, and see if it can predict the present with accuracy. Computers are often used to create this models because of the huge amount of data that need to be manipulated.

This neurological disorder often damages the insulating material covering nerve cell fibers. Transverse myelitis interrupts the messages that the spinal cord nerves send throughout the body.</span>
