What pair of statements about Blehert's and Behr's work represent an observation that was first made directly in the field and then a repeat, reinforcing observation made in the lab? Choose one or more:

A. A microbiologist with the U. S. Geological Survey grew crescent-shaped fungal spores in a lab on refrigerated plates.

B. A specialist with the New York State Health Department, on an exploration, found dead bats with white noses.

C. A specialist with the New York State Health Department detected crescent-shaped fungal spores when examining a sample swabbed directly from a living bat with a white nose.

D. A microbiologist with the U. S. Geological Survey grew crescent-shaped fungal spores in a lab at room temperature.

The correct answer are option A. "A microbiologist with the U. S. Geological Survey grew crescent-shaped fungal spores in a lab on refrigerated plates" and option C. "A specialist with the New York State Health Department detected crescent-shaped fungal spores when examining a sample swabbed directly from a living bat with a white nose".

Explanation:

Doctor Blehert and Doctor Behr are two scientists that are studying the relationship between fungal disease and the development of the bat white nose syndrome. In order to prove that bat white nose syndrome is caused by a fungal disease Blehert and Behr first took samples in the field and later analyzed the samples in the laboratory. First, a specialist with the New York State Health Department detected crescent-shaped fungal spores when examining a sample swabbed directly from a living bat with a white nose. Later, the samples taken from the shaped fungal spores were grew in the laboratory on refrigerated plates by a microbiologist with the U. S. Geological Survey. After analyzing the samples, the scientists conclude that the bat white nose syndrome is caused by a fungal disease.
