Liters and milliliters are the most commonly used. Many may think it would be cups and quarts and whatever, but liters are part of the SI units and used in all other countries.
An object is exerting a force when it pushes or pulls on another object.Objects commonly exert forces when they hit each other, as when a bat hits a ball.They can also exert a force with out touching. This happens when the object has "field" around it. Common fields are magnetic, electric or gravational. The Sun's gravity exerts a force on the earth even tho it is very far away.
1870-1959, American biologist and anatomist, b. Germantown, Pa., Ph.D. Johns Hopkins, 1894. He went to Yale as professor of comparative anatomy in 1907 and held various honorary positions there until his death. He is known for his work on nerve development in the embryo and on nerve regeneration as well as for his discovery of a method of tissue culture that permits study of isolated living cells in a controlled environment.
Some include radar, computer technology, jet propulsion, medecal advances, rocket technology, weather data collection and reporting, nuclear technology and the list goes on.
It really, REALLY depends on the kind of lab you mean. Some labs deal with blood, some with DNA, some with computers, and so on and so on. So, there's a whole lot of different equipment that can be used! In an academic lab for a school or university, there's a sampling of all sorts of equipment you'd use in a real-world setting. There's beakers and flasks of all shapes and sizes for measuring liquids, along with test tubes for reactions. They also use balances, stains, microscopes, slides (pre-mounted and plain), live specimens (such as protists) and preserved specimens (like the frogs you dissect in high school). There are incubators, autoclaves, water baths, all sorts of fun chemicals, pipettes for transferring small amounts of liquid, centrifuges, petri dishes and different kinds of agar (the gel that goes into petri dishes). And there's dissecting material, like scalpels, pins and probes. Most labs have all kinds of safety equipment depending on the safety of the chemicals used. In many commercial labs and laboratory classrooms you might find an eye wash station, fire blanket, shower, glass disposal box, gas shut-off switch, and that big poofy pillow you sop up chemical spills with. That's just a tiny, insignificant sample of standard equipment in a lab. Of course, I'm sure other people can offer many more examples than I came up with.
