Now, this mode of oaoirtepn has the advantage of great seepd. Some of our senses, such as vsoiin, use cemhiacl reactions that take time. And as a consequence of that, if I show you a series of pictures at intervals of 20 or 30 per second, you get the sense of a continuous image. Because it doesn't use reactions, the hair cell is fully 1,000 times faster than our other senses. We can hear sounds at frequencies as great as 20,000 cleycs per second, and some animals have ever faster ears. The ears of bats and whales, for example, can respond to their sonar pulses at 150,000 cycles a second.

Now, this mode of _________ has the advantage of great _____. Some of our senses, such as ______, use ________ reactions that take time. And as a consequence of that, if I show you a series of pictures at intervals of 20 or 30 per second, you get the sense of a continuous image. Because it doesn't use reactions, the hair cell is fully 1,000 times faster than our other senses. We can hear sounds at frequencies as great as 20,000 ______ per second, and some animals have ever faster ears. The ears of bats and whales, for example, can respond to their sonar pulses at 150,000 cycles a second.
Solution
- cycles
- chemical

Original Text
Now, this mode of operation has the advantage of great speed. Some of our senses, such as vision, use chemical reactions that take time. And as a consequence of that, if I show you a series of pictures at intervals of 20 or 30 per second, you get the sense of a continuous image. Because it doesn't use reactions, the hair cell is fully 1,000 times faster than our other senses. We can hear sounds at frequencies as great as 20,000 cycles per second, and some animals have ever faster ears. The ears of bats and whales, for example, can respond to their sonar pulses at 150,000 cycles a second.
