Ants don't have lungs ... Air comes in and goes out through pores so they don't have control on this process. But they need air. A friend of mine thinks that ants can hold their breath underwater for up to 14 days.

In my opinion a single drop of water could kill an ant. And 14 days without eating or being exposed to the sun light would lead to their death, wouldn't it ?

I don't want to influence your replies though.

Does anyone know ?

I wander around a bit each day, hoping to find a question which I may be able to answer, and then I find stupid stuff like this

http://answers.yahoo.com/question/index;_ylt=Au_01vRpn1cvFX8uC9Q2HiTzy6IX?qid=20061019185132AArsjfj

By time I have time to leave a sarcastic answer, she has 3 more just as annoying questions posted. Do you think Yahoo Answers should have a "pointless question" option on each question?

it assume every particles in the universe have an antiparticles ie(proton has antiproton, electoron has positron) usually when a particle meet there counter part they annihlate each other; because they have opposite charges. Neutron also have antiparticle but neutron doesn't have any charges. How can they annihilate each other?

I'm a senior in high school and I'm really interested in physics and math, and I wanted to know some available careers in the physics field. I know engineering is one of them. It would be nice if you gave me the career and a brief explanation of what that career does.

ok well let me tell you whats going on i'm not just trying to get out of my home work. i'm doing a science project and i'm almost all done, but it's really hard. for one i can't look at the computer for very long because it hurts my eyes my eyes can't be around bright lights it's something that i was born with i guess. i guess it doesnt' really help that i'm really dumb when it comes to computers. well when i have to look up stuff i can never find what i need. ok well if any one thinks they can help me with any of this work i would be so thankful.

i need to find five bacteria, five fungi, and five protist common and scientific names, what they eat, what eats them, their reproduction, and their habitat.

thanx a hole lot for any time and help.

This question has to do with this question regarding the size of a battery. For instance the AA battery is larger than the AAA battery. Here is the link to that.

Can you use an extra large battery (such as a lantern battery) with 1.5volts to take the place of a AAA 1.5volt battery? Of course, you may have to use a stepdown transformer if the lantern batter carries more than 1.5volts. Perhaps a resistor would do the trick. I don't know.

But, to put it more simply. Could a AA size battery with 1.5volts take the place of a AAA battery with 1.5volts?
