AI Thread Summary
Mosquitoes can see in the dark primarily due to their ability to detect carbon dioxide, which is exhaled by animals, allowing them to locate hosts even in low light. This sensory perception helps them navigate and find blood sources at night. The discussion also mentions other insects, like bees and certain shrimp, that can see in ultraviolet light, but emphasizes that mosquitoes rely on carbon dioxide detection rather than vision. The comparison to the South American Kissing Bug illustrates a similar feeding behavior, highlighting the importance of carbon dioxide in nocturnal feeding. Understanding these mechanisms is crucial for research on mosquito behavior and control.

Does anyone know why a mosquito can see in the dark?
(stupid physics teacher gave me this topic to research on)
please help

I do know bees and some species of shrimp see in ultraviolite light, its called "bee's purple," and some snakes see heat too. Try posting this again in the biology forum. It might help. :wink:
 
Ohhhhh, I think I know what you're talking about.

Mosquitoes are attracted to carbon dioxide, exhaled by most animals with blood. So, they know where someone is in a dark room because they can sense the varying degrees of the intensity of how much, carbon dioxide.

Another example is the infamous, deadly South American Kissing Bug. The name comes from its how it feeds. It feeds at night, attracted to carbon dioxide, it sucks blood by an animal's cheeks and/or lips while it is sleeping.
 
really? so then it has nofin to do with they eyes
 
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Thread 'Struggling to make relation between elastic force and height'
Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
