Here are the sentences with the appropriate words filled in:
Plant leaves are the ideal model for a lot of solar technology, so it only makes sense that manmade solar panels would look to Mother Nature to improve the efficiency of their designs. Over time, solar cells wear down — just like amber due to degradation caused by ultraviolet light. A team of researchers revealed this week that they have created a new type of solar cell that can repair and reinvigorate itself by mimicking the functioning of organic vascular systems found in nature.
In 1996, Dieter Gurtler and his colleagues from the Mercedes Technology Center in Germany, were looking for a model for a holistically conceived bionic car, respecting at once physics, design, and aerodynamics. The team's first instincts were to use streamlined sharks, penguins, dolphins, and tunas. But on a visit to the Rosenstein Museum in Stuttgart, with its huge collection of preserved fish, it became clear that their "ideas of tunas and sharks were not useful to design cars, which contain a cubicle for passengers, while swiftly-swimming fishes are compressed." It was their idea to choose a slowly but steadily swimming fish, and the kingfisher was the first option.
The "architecture" of termite mounds creates a natural air-conditioning system that runs all by themselves. Termites are amazing little critters. They are tiny, even by insect standards, yet they build towers as high as 7 meters to house colonies that can consist of several million.
So, the words are filled in as follows:
- Plant leaves
- Kingfisher
- Termite mounds
