Within an integrated circuit, each wafer is cut into sections, which a. have multiple circuits and are placed all together in one case. b. carry a single circuit and are placed all together in one case. c. have multiple circuits and are placed in individual cases. d. carry a single circuit and are placed in individual cases

The answer is D. 

An integrated circuit (IC) is a circuit that’s built up by depositing a series of thin layers of film on a base material. The base material is usually a thin disk or wafer of germanium or silicon about one inch in diameter. After the desired number of layers of film has been deposited on the base in succession, the surface of the wafer is divided into many tiny squares. Then, each square is converted by certain precise processes into a complex electronic circuit with many components. Finally, each wafer is cut into sections so that each section carries a single circuit, and each section is placed in an individual case.

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
