Original Answer: The pearl facets introduce certain body features and adaption of pearl beads when they experience extremely cold conditions. The first one is their thick fur. The dark color fur can receive more sunlight heat and it can protect the light directly on their thick skin. The second is their fur is with oil. The oil can keep water away their fur and help them to keep their warm when they are swimming.

Corrected Answer: The pearl facets The lecture (将“pearl facets”改为“the lecture”，因为原文中没有提到“pearl facets”，而是讲座的内容) introduces d (将“introduces”改为“introduced”，以保持时态一致) certain body features and adaption adaptations (将“adaption”改为“adaptations”，以保持与原文一致) of pearl beads polar bears (将“pearl beads”改为“polar bears”，因为原文中讲的是北极熊，而不是珍珠) when they experience extremely cold conditions. The first one is their thick fur. The dark colored (在“color”后面加上“ed”，使其成为形容词) fur can receive absorb (将“receive”改为“absorb”，以更准确地描述光和热的吸收过程) more sunlight heat and it can protect the light bears (将“light”改为“bears”，以保持与原文一致) directly on their thick skin. The second is their fur is with oil. The oil can keep water away their from their (在“their”前面加上“from”，以表示与水的隔离) fur and help them to keep their warm when they are swimming.

Revised Answer (140 words): The lecture introduced two key adaptations of polar bears that enable them to survive in the harsh Arctic environment. The first adaptation is their thick, dark-colored fur, which helps them retain heat from sunlight. The dark color of the fur allows it to absorb more sunlight and heat, providing insulation and warmth for the bears in the cold conditions. The second adaptation is the presence of oil in their fur, which makes it waterproof. This oily layer prevents water from soaking into the fur, ensuring that it remains an effective insulator even when the bears are swimming in icy waters. These two adaptations work together to help polar bears maintain their body temperature and thrive in their extreme habitat.
