1. Given the following data before execution of instruction,

Address	Contents
20002	EDBC
20004	345C
20006	08BC
20008	BE60
2000A	2CA7

(DS)=(SS)=2000H

(SP)=0006H

BX=0003H

AX=A34DH

for each of the indicated instructions (executed separately), write the expressions for the effective addresses of the source and destination operands in register transfer language, calculate them, and give the resulting contents of register and the contents of affected memory locations after execution.

1. ADD BX, [1003]
2. PUSH BX
3. POP BX
4. AND AX, [BX+0004H]
