In the book "Jurassic Park" does the Lysine Contingency actually get explained?


I was watching the movie recently and noticed that one of the characters (very) briefly mentions a safety they built into the system should any of the dinosaurs escape. They called it the Lysine Contingency saying that all the dinos have been genetically modified to depend heavily on lysine in their diet, so if any of them escape they wouldn't be able to survive without the food supplements that the park gives them.


Why doesn't the story end right there? Does the Michael Crichton book actually explain this in depth?



Answer



They found other sources of lysine, including beans and chickens.




"...This spring, in the Ismaloya section, which is to the north, some unknown animals ate the crops in a very peculiar manner. They moved each day, in a straight line-almost as straight as an arrow-from the coast, into the mountains, into the jungle."
Grant sat upright.
"Like a migration," Guitierrez said. "Wouldn't you say?"
"What crops?" Grant said.
"Well, it was odd. They would only eat agama beans and soy, and sometimes chickens."
Grant said, "Foods rich in lysine..."

harry potter - Did Dolores Umbridge Have Any Association with Voldemort (or Death Eaters) before His Return?

I noticed that Dolores Umbridge was born during the first Wizarding War, so it's very likely she wasn't a Death Eater then (but she is pretty evil -- who knows?). After that Voldemort was not around in a way that could affect many people, and most wouldn't know he was planning to rise again. During that time, and up through Voldemort's return (in Goblet of Fire ), did Umbridge have any connection with the Death Eaters or with Voldemort? Was she doing what she did on her own, or was it because of an association with Voldemort or his allies? Answer Dolores Umbridge was definitely not a good person. However, as Sirius points out, "the world isn't split into good people and Death Eaters". Remember that he also says that he doesn't believe Umbridge to be a Death Eater, but that she's evil enough (or something like that). I think there are two strong reasons to believe that: Umbridge was proud to do everything according to the law, except when she trie...

futurama - How much time is lost in 'Time Keeps on Slippin''

In time Keeps on Slippin' , Farnsworth creates a basketball team which he matures by abusing Chronitons. This leads to time skipping forward by random, but ever increasing amounts. How much time was skipped in this way? Answer Unfortunately, I don't think a good estimate can be made for this, for two reasons: Many of the time skips move forward by an indeterminate amount of time. At one point, the Professor mentions localized regions of space skipping forward much more than others. We then see two young boys on the street below complaining about having to pay social security, only to suddenly become senior citizens and start complaining about wanting their money. Thus, each individual could have experienced a different amount of time skippage.

aliens - Interstellar Zoo story

I vaguely remember this story from my childhood: it was about an interstellar zoo that came to Earth with lots of bizarre and unusual species, and humans would file through and gape at all the crazy looking creatures from other planets. The twist came at the end when the perspective shifted to the other side of the bars and we discovered that the "creatures" were traveling through space on a kind of safari. They thought they were the visitors and we were the animals. Neither side knew that the other side thought they were the zoo creatures. Answer Got it. Zoo, by Edward D. Hoch. Published in 1958.

harry potter - What is the difference between Diffindo and Sectumsempra?

In the Harry Potter books, Diffindo is called the 'Severing Charm' and it’s most commonly used to cut ropes and the like. However, in the last book Hermione uses it on Ron but misses, creating a 'slash in his jeans' and his knee gets cut, causing him to 'roar in pain'. We've only seen Sectumsempra used once on screen when Harry directly uses it on Malfoy in the sixth book, but there it's mentioned that he is 'waving his wand wildly'. Wouldn't Diffindo, if used in such a fashion also cause a similar effect? Similarly, if it was able to cut Ron, it would also be able to, say, chop off an ear (George's)? In that case, how are these two spells different, except for Sectumsempra seemingly used exclusively to hurt humans? Answer While Diffindo and Sectumsempra both can be countered by other spells, Diffindo is far more easily countered. Reparo, a relatively common spell, can completely reverse its effect when used once. “He pulled the old cop...
