Answer:
A : Telophase
Explanation:
the final phase of cell division, between Anaphase and Interphase, in which the Chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
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.
Answer:
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.
The pair of statements that represent a direct field observation and a reinforcing lab observation are 'A specialist found dead bats with white noses' and 'A microbiologist grew crescent-shaped fungal spores in the lab'. These statements show how an initial field observation of bats' white noses led to a lab study where the associated fungus was grown, solidifying the link between the two.
The correct pair of statements representing an observation made directly in the field and then reinforced in the lab are B and A respectively. Let's understand why:
B. A specialist with the New York State Health Department, on an exploration, found dead bats with white noses. This constitutes an initial observation in the field of study. The specialist observed that bats in their natural habitat had contracted a peculiar condition (white noses) and were subsequently dying. This spurred the need for further investigation.
A. A microbiologist with the U.S. Geological Survey grew crescent-shaped fungal spores in a lab on refrigerated plates. After the field observation, the phenomena was then studied in a controlled lab setting. The microbiologist was able to grow the similarly crescent-shaped fungal spores, that were suspected to cause the white noses, in lab conditions. This confirmed the field observation and further strengthened the potential link between the observed white-nose condition in bats and the presence of this particular fungus.

The similarities between compound light microscopes and electron microscopes are as follows:
An electron microscope may be defined as a technical instrument that is significantly utilized in order to obtain a high-resolution image of biological and non-biological specimens with the help of a beam of accelerated electrons.
The differences between compound light microscopes and electron microscopes are as follows:
Therefore, the similarities and differences between light and electron microscopes are distinctly explained.
