Answer:
Loose of body hair, reduction of body fat percentage and changes in life habits.
Explanation:
One of the most notorious changes would be the loss of body hair, due to the temperature increase. The amount of hair that polar bears now posses, helps them with keeping their body warm in very cold temperatures, as well as the body fat, which would also be reduced because of the excess of heat. Finally, their life habits could also change, as for example, part of the body fat helps them with hibernation, so these periods could be reduced or even lost.

Answer:
In the apical layer of the pseudostratified ciliated columnar epithelium.
Explanation:
The sustentacular cells work as metabolic and material assistance for the olfactory epithelium. Analogous to neural glial cells, maintaining non-neural cells in the olfactory epithelium that are found in the apical zone of the pseudostratified ciliated columnar epithelium. The olfactory epithelium, located inside the nasal cavity, consists of olfactory receptor cells, which possess functional cilia expansions. The cilia trap odor molecules as they cross beyond the epithelial exterior. Data regarding the molecules are then forwarded from the receptors to the olfactory bulb in the brain. There exist two types of maintaining cells in the olfactory epithelium: sustentacular cells and microvillar cells.
