With this information in hand, biologists can determine how many animals can be shot each year without endangering the herd.

By comparing genomes of different species, biologists have more accurately determined how these species are related to one another.

We may speculate, but only by examining life elsewhere can biologists truly determine what else is possible.

Through sexing, biologists and agricultural workers determine the gender of livestock and other animals they work with.

To do this, biologists determine and then compare the mtDNA sequences from different individuals or species.

"The biologist starts with a big piece of forest and determines the larger organisms," Dr. Wilson said.

No biologist could determine the cause with certainty.

From such evidence, biologists have determined that the giant squid is the world's largest invertebrate animal.

For one thing, biologists must determine that human brains harbor a similar population of progenitor cells.

Now, biologists can determine the proteins in a sample in seconds rather than weeks.
