In the body, hemoglobin (Hb) is the substance responsible for transporting oxygen (O2) to tissues. Hemoglobin binds oxygen to produce oxyhemoglobin (HbO2):
Hb + O2 ? HbO2
Carbon monoxide (CO) can also bind to hemoglobin to produce carboxyhemoglobin (HbCO):
Hb + CO ? HbCO
The equilibrium constant for Reaction 2 (KCO) is about 210 times larger than the equilibrium constant for Reaction 1 (KO2). Thus, carbon monoxide binds to hemoglobin much more efficiently than oxygen.
KCO/KO2 = 210
a. Write a balanced equation for the displacement of oxygen from HbO2 by CO to produce HbCO. Write the equilibrium constant expression for your overall reaction.
b. Write an expression that relates the equilibrium constant for the overall reaction (i.e., from Question 1) to the equilibrium constants KCO and KO2.
c. Use your balanced equation from part (a) and your knowledge of equilibrium constants to explain why patients who are experiencing CO poisoning are generally given pure oxygen as a remedy.

Question 1
A substring of String s is a sequence of k >= 0 characters in s, in the order in which they occur in s.
The letters in a substring may be either contiguous (next to each other) or non-contiguous in the original String s.
For instance, these are the substrings of String s="abc".
String s All substrings of s
======== ==================================
"abc" "" "a" "b" "ab" "c" "ac" "bc" "abc"
Write a function allSubstrings that returns an ArrayList containing all the substrings (contiguous or non-contiguous) of a String parameter s, and test it on the String "abcde".
// Return all substrings of the String s
public static ArrayList allSubstrings(String s) { ... }
Question 2
Implement a function that reads numbers in from a file with one number per line and outputs all the possible sums that can be formed by subsets of the numbers. For instance, if the numbers in the file are 1 2 4, then the output would be 0, 1, 2, 4, 3, 5, 6, 7. Note that 0 is in the output because it uses none of the numbers, while 7 is the sum of all of the numbers.
// Return all sums that can be formed from subsets of elements in arr
public static ArrayList allSums( ArrayList arr ) { ... }

Write an ASM program that evaluates the following expression, using variables: Z = (-A - B) - (-C - D) 1. Declare and initialize the memory variable A to 32-bit signed integer value 543210 and variable B to 16-bit signed integer value -3210. 2. Declare the memory variables C and D and read in their values from the keyboard as 32-bit signed integer value 43210 and 8-bit signed integer values -10, respectively. a. You should display a message asking for the value of the variable, for example: “What is the value of C?” then b. Read in the value of C from the keyboard and then c. Display the value you have read beside (ie, to the right of) the message “What is the value of C?”. Then repeat for variable D in the next line. 3. Variable Z should be declared as a 32-bit signed integer.
4. Display the string “Z = (-A - B) - (-C - D)” alone in a single line. 5. Display the values of all the variables A, B, C, D together in the next line (in the order in which they appear in the expression); each separated by 3 spaces and a semicolumn and 3 spaces again. 6. Display an empty line. 7. Display the final result contained in variable Z, in binary, then in decimal, and then in hexadecimal; each in a separate line.

Can you please explain and show how you would complete the following SQL Injection Attacks tasks using the SEED lab seed Ubuntu 16.04 Virtual Machine:
Task 3.1: Modify your own salary.
As shown in the Edit Profile page, employees can only update their nicknames, emails, addresses, phone numbers, and passwords; they are not authorized to change their salaries. Assume that you (Alice) are a disgruntled employee, and your boss Boby did not increase your salary this year. You want to increase your own salary by exploiting the SQL injection vulnerability in the Edit-Profile page. Please demonstrate how you can achieve that. We assume that you do know that salaries are stored in a column called salary.
• Task 3.2: Modify other people’ salary.
After increasing your own salary, you decide to punish your boss Boby. You want to reduce his salary to 1 dollar. Please demonstrate how you can achieve that.
• Task 3.3: Modify other people’ password.
After changing Boby’s salary, you are still disgruntled, so you want to change Boby’s password to something that you know, and then you can log into his account and do further damage. Please demonstrate how you can achieve that. You need to demonstrate that you can successfully log into Boby’s account using the new password. One thing worth mentioning here is that the database stores the hash value of passwords instead of the plaintext password string. You can again look at the unsafe edit backend.php code to see how password is being stored. It uses SHA1 hash function to generate the hash value of password. To make sure your injection string does not contain any syntax error, you can test your injection string on MySQL console before launching the real attack on our web application.
Please include screenshots along the way, thank you!
