How did Darwin and Lamarck differ in their thinking about change in species? A.
Darwin thought that organisms could induce their own changes, while Lamarck thought that change could only be induced by an organism’s environment.

B.
Darwin thought that change could occur in individual organisms, while Lamarck thought that change could only occur across generations.

C.
Darwin thought that genes controlled a species’ ability to survive, while Lamarck thought that genes were only one part of a species’ ability to adapt.

D. Darwin thought that organisms had to struggle to survive, while Lamarck thought that organisms could make adjustments when conditions became difficult.

Acommercial grade cubical freezer, 4 m on a side, has a composite wall consisting of an exterior sheet of 5.0-mm thick plain carbon steel (kst= 60.5 w/m k), an intermediate layer of 100-mm thick polyurethane insulation (kins 0.02 w/m k), and an inner sheet of 5.0- mm thick aluminium alloy (kal polyurethane insulation and both metallic sheets are each characterized by a thermal contact resistance of r 2.5 x 104 m2 k/w. (a) what is the steady-state cooling load that must be maintained by the refrigerator under conditions for which the outer and inner surface temperatures are 25°c and -5°c, respectively? (b) for power saving purpose, which wall material should be increased/reduced in. thickness in order to reduce 50% of the cooling load found in part (a)? redesign the thickness of the proposed material. 177 w/m-k). adhesive interfaces between the q=575.93 w
