Yes, a 15-degree line would form a closed loop for temperature obtained from several stations in Canada near the Great lakes.

Temperature refers to a measure of the degree of hotness or coldness of a physical body (object). Also, temperature is typically measured by using a thermometer and its units are:

An isotherm can be defined as a line that is drawn on a map to join points with the same temperature, so as to show the distribution of temperature in a geographical region on Earth's surface.

In Meteorology, a closed loop is used to show or depict where an air mass is located when drawing isotherms. Thus, a 15-degree line would form a closed loop for temperature obtained from several stations in Canada near the Great lakes.

Camouflage or coloration is an animal trait that is based on Darwin's theory of natural selection.

Natural selection may be defined as the process through which populations of living organisms adapt and change. Natural selection leads to favorable variations among the organisms.

Coloration is the general appearance of an organism as determined by the quality and quantity of light that is reflected or emitted from its surfaces. These are determined by some dominant traits in organisms.

Therefore, Camouflage or coloration is an animal trait that is based on Darwin's theory of natural selection.
