The Difference in Temperature Preference Between Two Populations of Daphnia $\degree$

question 34

Essay

The difference in temperature preference between two populations of Daphnia water fleas is due to a mutation. The original population prefers temperatures near 20 $\degree$ C, while the mutant population prefers temperatures between 25 $\degree$ C and 30 $\degree$ C. Predict how natural selection might affect the geographical distribution of these two populations.

Compare different theories related to roles in groups and their implications.

Reflect on personal role tendencies within group settings in terms of task and relationship orientations.

Examine roles within family units and compare them to roles within other small groups.
