a farmer has a herd of sheep with an average weight of 200 pounds. the heaviest sheep weigh around 350 pounds. he wants to know if the weight of the sheep is genetic. so, he breeds two of his heaviest sheep. the offspring grow up to weigh 300 pounds.
when calculating the heritability, the selection is the response .

a 350 a 300
b 300 b 200
c 200 c 150
d 150 d 100

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide: cac2 (s) + 2h2o (g) → c2h2 (g) + caoh2 (s) =δh−414.kj in the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6c2h2 (g) + 3co2 (g) + 4h2o (g) → 5ch2chco2h (g) =δh132.kj calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. round your answer to the nearest kj .
