I don't have time to talk to you. I'm as busy as a beaver. When the tourist season starts, this store is busy as Grand Central Station. Sorry I can't go to lunch with you. I'm as busy as a beaver building a new dam.
The expression adaptive strategies is used by anthropologist Yehudi Cohen to describe a societyâs system of economic production. Cohen argued that the most important reason for similarities between two (or more) unrelated societies is their possession of a similar adaptive strategy.In other words, similar economic causes have similar sociocultural effects.astoralists live in North Africa, the Middle East, Europe, Asia, and sub-Saharan Africa. These herders are people whose activities focus on such domesticated animals such as cattle, sheep, goats, camels, yak, and reindeer.
The adaptive immune system is one of the two main immunity strategies found in vertebrates (the other being the innate immune system). Adaptive immunity creates immunological memory after an initial response to a specific pathogen, leads to an enhanced response to subsequent encounters with that pathogen.he acquired response is called adaptive because it prepares the body's immune system for future challenges (though it can actually also be maladaptive when it results in autoimmunity).
