Answer:
39 + 3
42
393
Explanation:
In this line System.out.println("39 + 3"), the quotation marks are used to delimit a string, then when printed in the console the string is printed as-is.
In the next line: System.out.println(39 + 3), without the quotation marks, the 39+3 is treated as a normal addition and prints the result of the operation.
In the last line printed with the code System.out.println("39" + 3,; the symbol + is used to concatenate the string 39 with the number 3, since the string has no spaces they are printed together.
Answer:
Explanation:
The dual of a function means replace AND with OR and replace OR with AND.
XOR gate of A , B is
So, Dual of A XOR B is ( replace AND with OR and OR with AND)
Complement of A XOR B is 
(In finding compliment AND becomes OR and OR becomes AND ).
By inter changing the above product of terms
Complement of 
So, Dual of A XOR B = Complement of A XOR B.
Answer:
It has to be more specific and easier to understand because of its importance.

Explanation:
Multicellular organisms thus have the competitive advantages of an increase in size without its limitations. They can have longer lifespans as they can continue living when individual cells die. Multicellularity also permits increasing complexity by allowing differentiation of cell types within one organism.
