Bobcats are predators but that does not mean they have no enemies. One of the reasons bobcats are nervous around people is because they have the role of prey as well as hunter. At 2 to 3 feet long, bobcats…
Because science offers a way to answer questions about the cosmos in a clear, rational manner, with evidence to support it, a reliable procedure is necessary in order to obtain the best information. That procedure is commonly called the scientific…
