Do fireflies glow and heat up at the same time? This is the ant manor on July 16 today manor small class questions, many users do not know the answer, this article Xiaobian will be for everyone in detail, interested in the small partners, together with the small editor to see it!
Ant Manor Answer Knowledge Feed Campaign has begun!
Ant Manor is very fun, raising chickens can also do charity at the same time, the recent knowledge quiz can also send free feed.
Today's questions are:
Do fireflies glow and heat up at the same time?
Yes, glow and heat at the same time
No, fluorescent is cold
The answer is: no, fluorescent is cold
Introduction to the principle of firefly luminescence:
Fireflies (English: Firefly), also known as luminous, sedum, such as fluorescent, night illumination, fluorescent fireflies, supper candles, flaming night, etc., belongs to the Coleoptera firefly family, small beetles, because its tail can emit fluorescence, so it is called fireflies. This tail can emit light insects, about 2000 species, China's more common are black fireflies, Ji red fireflies, window chest fireflies and other several.
The glow of fireflies is a type of bioluminescence. The principle of glow of fireflies is that fireflies have specialized light-emitting cells, and there are two types of chemicals in light-emitting cells, one is called glowing hormone (called firefly luciferin in fireflies), and the other is called luciferase. Fluorescein consumes ATP under the catalysis of luciferase and reacts with oxygen, producing oxidized fluorescein in the excited state in the reaction, releasing photons when oxidized fluorescein returns from the excited state back to the ground state.
Almost all of the energy released in the reaction is released in the form of light, and only a very small part is released in the form of heat, with a reaction efficiency of 95%, so that the beetle does not overheat and burn. Humans have not been able to make such an efficient light source so far.
There are many white patches in the lower part of the worm's abdomen. In fact, it is the part of its carapace that is transparent to light. Inside there is a white film that reflects light. So during the day this part appears white.
Biological significance of luminescence: adults use species-specific flash signals to locate and attract the opposite sex, in order to complete the mission of courtship mating and reproduction, a small number of adult fireflies use flash signals to prey, and another role is as a warning signal, that is, when fireflies are stimulated, they will emit light.
Little friends go get the feed!
