A. personal
B. business
C. government
The correct option is C.
Economics as a course is divided into two major sub specialties, which are micro and macro economics. Micro economics has to do with the study of individual, households and businesses behaviors in decision making and uses of scarce resources. Macro economics on the other hand has to do with the study of how the whole economy behaves. Thus, macro economics is the study of how a nation's economy work and this usually involves the national government.
Macroeconomics focuses on the C. government level of an economy and studies economic factors at a national or global level.
Macroeconomics focuses on the government level of an economy. It involves the study of economic factors such as national income, employment, inflation, and fiscal and monetary policies at a national or global level. Macroeconomics aims to understand how government policies and economic indicators impact the overall functioning and health of an economy.
Thus, it is a branch of economics that studies the economy as a whole. Its primary uses include informing government policies, guiding central bank decisions, and aiding businesses in making strategic choices, all with the goal of promoting stable and sustainable economic conditions.

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.

Explanation:

Ans.
Symmetry in animals can be defined as the balanced distribution of identical body shapes or parts within an organism's body. All animals, except sponges have either radical or asymmetry.
Sponges belong to phylum Porifera, which exhibit asymmetrical body plans. Their body shapes are adapted for maximum efficiency of water flow through their central cavity.
Thus, the correct word to be filled in the blank is 'sponges.'
