Scientists

They spilt them up in groups.

we know by sticking a ruler into whatever and checking the millimeter mark and however many millimeters there are multiply them by 7.

One reason is that there were a lot of fossils in many layers of rock and then suddenly, there are a lot fewer.

Also, there don't appear to be many dinosaurs alive today. So, they went extinct.

Do you really mean "how" did the dinosaurs go extinct?

1. A Tesla Coil

2. A Jacob's ladder

3. Minions, don't forget minions.

*Personally, I always keep around a tank with a two-headed shark, but I don't think every mad scientist agrees that this is a lab staple.

So that we can learn more about ancient earth.

Through the science of archiology. They dig up the bones and other remains of animals, reassemble them kinda like a 3-D jigsaw puzzle, and study the skeletal sructure of the animal. This gives a lot of general information. They then study individual parts of the skeleton to learn some more detailed things. The teeth for instance will tell if they were an herbavore (with flat grinding teeth), a carnavor (with sharp cutting teeth), or an omnivor, with a combination of types of teeth (like humans have)

Scientists are studying, and trying to find ways to prevent or possibly cure WNS. In Boston, lab tests show that several drugs can fight the germ and that some antiseptics might help decontaminate areas where bats live.

they have developed space expedition , medicine, and computer communications technology. :D (SCIENCE)

They should try to reproduce Dr. Maxwell's research to verify his results.

The reason scientists like to use Fruit Flies for experiments, it because they have such a short life, that it won't really matter if you accidentally kill it. Also, when scientists conduct an experiment, they like to test it on large groups. Fruit flies can create 500 hundred babies in less than two weeks.

Alexander Fleming received his education in biology and medicine. He attended St. Mary's Hospital Medical School in London, where he earned his medical degree. He later conducted research in bacteriology and immunology, which laid the foundation for his groundbreaking discovery of penicillin.

Scientists use a system called taxonomy to name and classify organisms. This system categorizes organisms based on their shared characteristics and evolutionary relationships. The basic unit of classification is the species, and organisms are grouped into increasingly larger categories such as genus, family, order, class, phylum, kingdom, and domain.

Wegner's theory was not accept because he didn't have much evidence to support his theory with and scientists thought that there might have been a land bridge between the continents. Another reason to why his theory was rejected was that he was a foreigner, by that; the scientists didn't really take him seriously.

ergonomics information is available in print and on the Internet, published by organizations such as the Occupational Safety and Health Administration (OSHA), the National Institute of Occupational Safety and Health (NIOSH), the National Safety Council,

if 2 or more organisms have more than one of the following the same, they are closley related:

kingdom, phylum, class,order,family,genus,and species

When scientists talk about the diversity of life, they are referring to the variety of different species, genetic traits, and ecosystems present on Earth. This diversity is crucial for the health and stability of our planet's ecosystems and plays a key role in supporting human well-being.

The electrical starter. Before that, cars had to be cranked.

Science is knowledge. Theories are tested for veracity (truthfullness) and if they are found to be true and cannot be proven false they become the body of science.

It's called 'peer review', but they don't normally assign a grade, just (usually constructive) comments or criticisms.

This is called scientific method. First; you start off with a question, and then you try to guess an answer to your question with a hypothesis, then you run an experiment and analyze the results and come to a conclusion.

James Watson and Francis Crick are credited with discovering the double helix structure of DNA in 1953, with the help of Rosalind Franklin's X-ray diffraction images. Their groundbreaking discovery revolutionized the field of genetics and laid the foundation for understanding the molecular basis of inheritance.
