Q:i need the names of the organisms. like names of insects or fish or what ever they eat. give the organism's name. don't just say fish or insects. i need specific names.this is for a biology project.: Diet okorder /.. I'm sorry, I couldn't find any specific names, but here are some general ones. Sorry again.

Q:I know they will leave because last year they left after a few weeks. I have seen that they normally leave after a month. They annoy me and I want them gone. They have been around since the end of February or beginning of March. Does anyone else have these in their house. It seems like they are leaving slowly usually there is like 1 or 2 a day in moms room but the last 2 days there have not been any. They have been in my room, just one a day it seems like and maybe one in the kitchen. We swat them or spray them and they die eventually but when will they be gone atleast for a little while?: Crane flies are totaly harmless to humans.They fly for some time and fall down to earth.Ants will take them away.These flies never byte or sting. Pet Cats like to play with it and catch it.They will disappear after some time. Do you know that crane flies spend most of their lives underground in their larval forms, which are known as leatherjackest?. Leatherjackets were very common round here, and are a favourite food of the local crows .These leatherjackets transform into crane flies.Summer is their growth time.

Q:You know those big cranes that sometimes hang above constructed buildings. I usually thought a crane is used to build that crane but then how is that first crane that built the crane get there in the first place?: from the ground up

Q:Is a crane a type of pulley?: No. A crane is a machine to lift heavy things. It usually uses a pulley. A pulley is part of the crane.

Q:My hubby just passed his crane test yesterday, and I was wondering how much they pay? He was told to ask for 50k a year..that includes crane time where he works. Can we really ask that? He sets trusses for a big lumber company in Missoula Mt. Any help would be great.: Huh, I thought crane ops got paid by the tonnage they lift. Maybe there is a base pay in addition to it. But to answer your question, I don't know.

Q:how to build a crane using:woodelasticsgluescrews/boltsbottlessyringesnailsplastictin canand rubber tubingplease be detailed,thanks! :): Carefully. okorder has kit numbers and downloadable instructions for many Lego cranes. You might be able to find some of them on OKorder. You may not need to actually build the Lego crane. Instead, look at the model, determine the major pieces (wheels, turntable, arm, etc.). Then, look at your bundle of pieces and make something with the same function.

Q:the way u find them climbing with the building makes me wonder how they become this long and what is the mechanism for that: *Tower okorder /

Q:how long do i have to work as a yardhand in oilfeild to become a crane operator?: You need to get licensed or certified to operate the crane. make sure you are qualified before you start complaining about not getting more challenging work. The world needs ditch diggers to so get back to work.

Q:how do cranes get assembled ? on building sites?: They use hydraulic mobile cranes, (they're telescopic). I watched a crane being disassembled on a building site near my home. How did they do it before they had these mobile cranes? In Switzerland, in places where there are no roads they use helicopters.

Q:I want to win a watch from a skill crane at Dave and Buster's and I need some tips.: Be the crane, be the crane. Seriously, just aim at the biggest item with three openings and try to move the crane to get it. They should let people rotate the crane, but then it would be easy for them to lose money.
