The Permian period, which ended in the largest mass extinction the Earth has ever known, began about 299 million years ago. The emerging supercontinent of Pangaea presented severe extremes of climate and environment due to its vast size. The south was cold and arid, with much of the region frozen under ice caps. Northern areas suffered increasingly from intense heat and great seasonal fluctuations between wet and dry conditions. The lush swamp forests of the Carboniferous were gradually replaced by conifers, seed ferns, and other drought-resistant plants.
Early reptiles were well placed to capitalize on the new environment. Shielded by their thicker, moisture-retaining skins, they moved in where amphibians had previously held sway. Over time, they became ideally suited to the desert-type habitats in which they thrive today.

Answer: This is more of a guess based on what I already know about liquid in certain temperatures but I would say it would have to be related to the blood having a harder time congealing due to the molecules moving faster because of the temperature. You probably already know that atoms move faster in higher temperatures as opposed to cooler ones, therefore the process of congealment and essentially transitioning from liquid to solid would be easier/quicker in cooler temperatures where the atoms in and around the wound would be moving slower.
Explanation:
Microscope. You would place the specimen on the glass slide and then slide the glass slide underneath the microscope.
