Question

in biology, the different areas of study are connected and overlap in various ways, with concepts that cut across all disciplines. which pair of crosscutting concepts are best exemplified when birds fly south when winter comes to the united states, and north when spring arrives? choose one.
a. stability and change; scale, proportion, and quantity
b. systems and system models; scale, proportion, and quantity
c. patterns; cause and effect
d. energy and matter: flows, cycles, and conservation; patterns

Explanation:

Bird migration (south in winter, north in spring) shows a pattern (regular seasonal movement) and cause - effect (seasonal change causes migration). Option C matches this. Other options don't fit as well: A's concepts aren't relevant, B's system models don't apply, D's energy/matter isn't the focus here.

Answer:

C. patterns; cause and effect
