Thanks to this incredible ability, some dogs are now being trained to save at-risk animals by sniffing (嗅) out their droppings. At the University of Washington’s Conservation Cannes facility,20specially trained dogs have successfully tracked killer whale droppings, which only float briefly on the ocean’s surface. Analyzing these samples enables scientists to monitor the health of killer whale populations, which are under significant stress from food shortages, pollution, and boat traffic.
Beyond tracking animal droppings, conservation dogs are also trained for live animal detection, further showcasing their abilities. They can locate rare species in their natural habitats. Additionally, they are now used to tackle the non-native species that threaten the survival of the local wildlife. Dogs also take on other important roles. For example, at Kenya’s Mombasa port, dogs sniff out illegal wildlife products such as rhino horns and ivory. Across Africa, they work on the frontlines against illegal hunting, serving as a powerful security force enhancer.
While dogs may not be the ultimate solution to every conservation challenge. their incomparable abilities make them invaluable companions in the fight to protect our planet’s biodiversity.
12. Why are the figures mentioned in the second paragraph
A. To highlight the superiority of dogs’ sense of smell.
B. To suggest the amazing accuracy of dogs’ analysis.
C. To recognize the importance of conservation work.

D、取少量该溶液，降温至10℃时，有KCl晶体析出，但在20℃时不知道有无晶体析出，无法证明该溶液已经饱和，选项不符合题意。
故选B。
12．B
A、蒸发溶剂，使某溶液中有晶体析出，则原溶液可能不饱和，正确；
B、析出晶体后的溶液一定是饱和溶液，错误；
C、析出晶体后的溶液可能是浓溶液，也可能是稀溶液，如氢氧化钙溶液析出晶体后，是稀溶液，正确；
D、该物质的溶解度随温度的变化特点不知道，故降温不一定有晶体析出，正确；
