Researchers have noted that ants arrange their dead using the same
principles thought to produce the markings on animal skin and on tropical sea
shells, a first clear example of so-called Turing patterns in higher organisms.
Line Turing argued that activation occurs through a feedback process that amplifies
(5) small variations in the concentration of one of the ingredients, while inhibition
causes a concentration of activity to suppress the appearance of similar
concentrations nearby. Ant graveyards are an example of a self-amplifying
activation process: ants are more likely to drop a corpse on a pile than
elsewhere, and because collecting bodies and adding them to a pile sweeps the
(10) surrounding space clear, new cemeteries are inhibited from appearing in the
vicinity of existing ones. While activator-inhibitor mechanisms have previously
been proposed to explain how predators and prey distribute themselves across an
ecosystem, it is the first time such a system has conclusively proven that
Turing’s process operates at the level of colonies and ecosystems. [br] It can be inferred from the passage that which of the following might be an example of an inhibitor mechanism already proven to operate in nature?
选项
A、Preying mantis females cannibalize their mates, limiting population growth of their species.
B、Beetles tend to collect in large groups, causing internecine battles between colonies.
C、Sea turtles tend to avoid laying their eggs very close to one another, causing their progeny to distribute evenly throughout the ocean.
D、Birds which settle upon the peak of a mountain naturally tend to build nests together to achieve safety in numbers.
E、Oysters tend to develop only to a certain size, due to the limiting effects of bacteria growth within their shells.
