Jeremy is making a trail mix containing raisins and peanuts. Raisins cost $1. 50 per pound. Peanuts cost $2. 50 per pound. Jeremy spends $10. 50 to make 5 pounds of trail mix. He uses the table below to organize this information. A Table titled Trail Mix showing Pounds, Cost, and Total. The first row shows Raisins, with r, 150, and 1. 5 r. The second row shows Peanuts, with 5 minus r, 2. 50, and 2. 5 left-parenthesis 5 minus r right parenthesis. The last row shows Mixture, with 5, blank, and 10. 50. Which equation can Jeremy use to determine the amount of raisins in the trail mix? r 1. 50 = 1. 5r r (5 â€" r) = 5 1. 5r 2. 5(5 â€" r) = 10. 50 1. 5r 2. 5(5 â€" r) = 5.

answer; (c) run the name by everyone you can;

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'
