1To copy the contents of five contiguous memory cells starting at address A0 to the five cells starting at address B0, you can use the following assembly code: ```assembly 00: LOAD A, A0 ; Load the value from memory address A0 into accumulator A 01: STORE A, B0 ; Store the value from accumulator A into memory address B0 02: LOAD A, A1 ; Load the value from memory address A1 into accumulator A 03: STORE A, B1 ; Store the value from accumulator A into memory address B1 04: LOAD A, A2 ; Load the value from memory address A2 into accumulator A 05: STORE A, B2 ; Store the value from accumulator A into memory address B2 06: LOAD A, A3 ; Load the value from memory address A3 into accumulator A 07: STORE A, B3 ; Store the value from accumulator A into memory address B3 08: LOAD A, A4 ; Load the value from memory address A4 into accumulator A 09: STORE A, B4 ; Store the value from accumulator A into memory address B4 ``` This program assumes that A0, A1, A2, A3, and A4 represent the memory addresses of the source cells
