Total magnification of objects is 12x.
Dissecting microscopes are microscopes with only one set of lenses so they have less magnification than a compound microscope.
The eyepiece, or ocular lens of microscope, usually has a magnification of 10x. The numbers on magnification knob range from about 0.7 to 3. So, when you want to calculate the total magnification multiply the magnification on the eyepiece with the number on the magnification knob.

Answer:
migration, which is a response to an external stimulus
Explanation:
<u>The butterflies were migrating in response to external stimuli.</u>
Migration is the movement of organisms from one place to another in response to external stimuli. The stimuli could be for food, shelter, weather, etc.
<em>Flight in response to external stimuli is often due to the presence of danger as stimuli. The adrenal gland releases epinephrine which triggers physiological changes in the body and makes the organism decide whether to run, stay, or fight. </em>
In this case, the butterfly could have been migrating in response to the availability of flower nectars or pollen which serve as food for them. Once flowers are available during the spring, the butterflies come around and when the winter comes and the flowers disappear, they migrate away.
