Fleas are perfectly designed by\r\nnature to feast on anything containing blood. Like a shark in the water or a\r\nwolf in the woods, fleas are ideally equipped to do what they do, making them\r\nvery difficult to defeat. The bodies of these tiny parasites are extremely\r\nhardy and well-suited for their job.
A flea has a very hard exoskeleton,\r\nwhich means the body is covered by a tough, tile-like plate called a sclerite.\r\nBecause of these plates, fleas are almost impossible to squish. The\r\nexoskeletons of fleas are also waterproof of fleas are also waterproof and shock\r\nresistant, and therefore fleas are highly resistant to the sprays and chemicals\r\nused to kill them.
Little spines are attached to his\r\nplate. The spine the flea scurries through an animal’s fur in – search of\r\ngrooming pet tries to pull a flea off through the hair coat, these spines will\r\nextend and stick to the fur like Velcro.
Fleas are some of the best jumpers\r\nin the natural world. A flea can jump seven inches, or 150 times its own\r\nlength, either vertically or horizontally. An equivalent jump for a person\r\nwould be 555 feet, the height of the Washington Monument. Fleas can jump 30,000\r\ntimes in a row without stopping, and they are able to accelerate through the\r\nair at an incredibly high rate – a rate which is over ten times what humans can\r\nwithstand in an airplane.
Fleas have very long rear legs with\r\nhuge thigh muscles and multiple joints. When they get ready to jump. They fold their\r\nlong legs up and crouch like a runner on a staring block. Several of their\r\njoints contain a protein called resilin, which helps catapult fleas into the\r\nair as they jump, similar to the way a rubber band provides momentum to a\r\nslingshot. Outward facing claws on the bottom of their legs grip anything they\r\ntouch when they land.
The adult female flea mates after\r\nher first blood meal and begins producing eggs in just 1 to 2 days. One flea\r\ncan lay up to 50 eggs in one day and over 2,000 in her lifetime. Flea eggs can\r\nbe seen with the naked eye, but they are about the size of a grain of salt. Shortly\r\nafter being laid, the eggs begin to transform into cocoons. In the cocoon\r\nstate, fleas are fully developed adults, and will hatch immediately if\r\nconditions are favorable. Fleas can detect warmth, movement, and carbon dioxide\r\nin exhaled breath, and these three factors stimulate them to emerge as new\r\nadults. If the flea does not detect appropriate conditions, it can remain\r\ndormant in the cocoon state for extended periods. Under ideal conditions, the\r\nentire life cycle may only take 3 weeks, so in no time at all, pets and homes\r\ncan become infested.
Because of these characteristics,\r\nfleas are intimidating opponents. The best way to control fleas, therefore, is\r\nto take steps to prevent an infestation from ever occurring.
Using the information in the passage\r\nas a guide, it can be concluded that
