Based on the provided image, I can now solve the problem of calculating the actual size of the snout beetle specimen.
The solution involves three steps, which are clearly outlined in the image:
1.
Measure the length of the specimen in the image.
The image shows a ruler at the bottom and a red line drawn across the beetle to indicate its length. By reading the ruler, we can see that the length of the beetle in the image is 83 mm (from the 0 mark to the 8.3 cm mark).
2.
Convert the measured length from millimeters (mm) to micrometers (µm).
Since the final answer is required in micrometers, we need to convert the measurement. We know that:
1 mm = 1000 µm
Therefore, 83 mm = 83 * 1000 µm = 83,000 µm.
3.
Divide the length of the specimen image by the magnification factor.
The image states that the magnification is x320. This means the image is 320 times larger than the actual specimen. To find the real size, we divide the image size by the magnification.
Actual Size = Image Size / Magnification
Actual Size = 83,000 µm / 320
Actual Size = 260 µm
Therefore, the actual length of the snout beetle specimen is 260 micrometers (µm).
