Anonymous users2024-02-14Question 1: What does the compound eyes of flies give humans a clear understanding of? Camera, question two: What are the characteristics of the eyes of flies? Why is it one by one? Is there any use for it? Each small cell is an eye, and that is called a compound eye
The compound eyes of houseflies are made up of 4,000 small eyes, which can see almost 360 clearly. objects within range. The structure of the small eye is very delicate, it has a convex lens-like light collection device, called the corneal lens, which is a hexagonal convex lens on the surface of the small eye, and the conical crystal is connected to the optical nerve under these light collectors.
The nerve senses the light points coming from the light collector and senses the light**, which then creates a "point image", and the interaction of the images of many small eye points forms a "mosaic image". If one of the compound eyes of an insect is cut longitudinally and observed in a magnifying glass or microscope, the small and multi-edged eyes are clustered together, much like a wonderful kaleidoscope. Although the compound eyes of insects are made up of many small eyes, their eyesight is much less good than that of humans, dragonflies can see 1 2 meters, flies can only see 40 70 mm.
However, insects are very sensitive to moving objects, and when an object suddenly appears, bees can react in seconds. Predatory insects are more responsive to moving objects. Insects, like humans, can distinguish different colors, but different wavelengths than humans perceive.
Insects can perceive wavelengths ranging from 240 (ultraviolet) to 700 (yellow, orange) nanometers. Bees can't distinguish between orange-red and green; Nettle butterflies do not see green and yellow-green. Ordinary insects do not perceive the color red.
Under the inspiration of fly's eye enamel, people made a fly's eye camera composed of 1329 small lenses that can take 1329 high-resolution images at a time, which is widely used in military, medicine, aviation and aerospace.
Question 3: What did humans invent using the compound eye of flies? According to the structure of the fly's compound eye, people imitated the "fly's eye" camera.
Question 4: Why do the compound eyes of flies have any function and make them into cameras The number of small eyes of the compound eyes of flies is very large.
Enables fast and clear imaging.
Now researchers are also imitating the structure and function of the compound eye system of flies, using many small lenses with specific properties, gluing them together in a regular manner to make a "compound eye lens", which can be used as a lens to make a "compound eye camera", which can illuminate thousands of identical images at a time. With this kind of camera, you can get into the plate-making work of printing stamps.
Question 5: What would it be like for a person to have the ability to have a fly's compound eyes? That's not capability, that's a vision system with lower precision.
With the current standard of living of human beings, it must not be the best choice.
It's not a biology major, so I can't talk about Feng Xiaokong's professionalism.
People according to flies.
The structure of the compound eye is modeled after the "fly's eye" camera. >>>More
Mosquitoes rely on their sense of smell to identify the location of food at long distances, and their super-sensitive sense of smell can always find a way to get closer to people (this is something that many animals have). Once close to the person, it uses thermal infrared to perceive the proximity of the blood vessels in the human epidermis**, and chooses the place of the lower mouth, (in its eyes, it is like the color of the animal seen by the heat sensor). Close to the crimson area, use the tip of the blade mouthpart (scalpel principle) to make an incision**, secrete your own saliva to reduce the pain of the other person (the principle of anesthesiology), and use a pump mouthpiece to suck in blood (syringe principle). >>>More
Flies are harmful to humans because they carry a variety of pathogenic microorganisms, the body surface of flies is hairy, the foot pads can secrete mucus, like to crawl and forage in human or animal feces, urine, phlegm, vomit and corpses, etc., and it is easy to attach a large number of pathogens, such as Vibrio cholerae, typhoid bacillus, dysentery bacillus, hepatitis bacillus, polio bacteria, hepatitis A bacteria, hepatitis B bacteria, and roundworm eggs; It often stays on the human body, food, and dining utensils, and has the habit of rubbing feet and brushing the body when it stops, and the pathogens attached to it quickly contaminate food and dining utensils When flies eat, they first spit out the bursal fluid, dissolve the food before they can be inhaled, and while eating, spitting, and pulling; In this way, the pathogens that were originally eaten into the digestive juice are spit out together, contaminating the food it has eaten, and people will get sick if they eat these foods and use contaminated dining utensils The epidemic of cholera, dysentery and bacterial food poisoning are directly related to the spread of flies, so, of course, it cannot be eaten.
Flies have a very sensitive sense of smell, so they prefer strong smells. It will eat some fruit flies, insects, etc. It is omnivorous. >>>More
Egg larvae (maggots) pupal process of adult fliesThe fly production process takes only about 1 day, and it can be shortened when the temperature is high. After 10 days, these 1 eggs become adult flies, so a fly can reproduce thousands of flies in its lifetime. >>>More
