Document Summary

Exercise physiology: the study of how the structures and functions of our bodies are altered when exposed to both acute (short term) and chronic (long term) sessions of exercise and or recreational physical activity. Exercise disrupts homeostasis: has positive effects on the structure and function of the human body. Structure and function are related: ex: heart is shaped in a way the allows it to receive and pump blood efficiently, ex: teeth shaped in order to better tear and grind food. Chemical level: atoms = the smallest building blocks of life. 99% of the body is made up of oxygen, carbon, hydrogen and nitrogen. The other 1% - calcium, phosphorus, potassium: atoms combine to make molecules (proteins, carbs, fats, nucleic acids aka dna) Cellular level: nonliving chemical components much be arranged in a precise way to form a living entity, cells are the basic units of life. Contents of each cell is enclosed by the plasma membrane.

5. 110 marks] Consider the card structure definition. (define-struct card (value suit)) ii Acara is a structure (make-card v s), where ji v is an integer in the range from 1 to 10 and iis is a symbo. for suit, from the set 'hearts, ii 'diamonds, 'spades, and 'clubs. a) [2 marks] Define a constant called four-of-hearts corresponding to the card with suit 'hearts and value 4. Consider the Scheme function merge-cards which consumes two card structures (cl and c2) and produces a new card, according to the following rules: . If the suits of the two cards are the same, the new card has that suit and its value is the sum of the values of cl and c2, up to a maximum value of 10 • Otherwise, the new card has the value of cl and the suit of c2. b) 12 marks Write the contract of merce-cards (the function header is given below). c) 12 marks Write a single example for merge-cards. d) 16 marks Complete the body of the function merge-cards.

Question 6.6 MARKS] Two friends like to send messages to each other, but they don't want anyone else to read the messages. To keep the messages private, they change each letter in the original message to a different letter of the alphabet. For every letter, they both know which letter will be substituted for it, which is called an encoding. The message will contain only lowercase letters. It will not contain whitespace, digits, or punctuation. The receiver of a secret message doesn't want to convert it back to the original message by hand. Instead, that person asks you to write a function to do it. Following the function design recipe, define a function that given a secret message and the encoding used, returns the original message. Choose a meaningful function name, and add a docstring that includes the type contract, the description, and two examples that return different values. You must choose the types to use to represent the data, and you will be marked not only on the correctness of the function, but also on your choice of data structures.

You have been contracted by a popular fitness club to create a Java Program that
will help in the input, calculation, display of calories burnt and pounds lost during a week of
workout for members of the club.
The program will also base on the amount of weight lost update the weight of the user and
calculate and display the users BMI – body mass index using any researched method. See an
example here- http://www.whathealth.com/bmi/formula.html
The club takes part in 5 major types of activities, namely walking, running, swimming, hiking,
and bicycling.
The program is to prompt for the Name of the member, gender, weight in pounds, height and
the time spend on each activity during the week in minutes.
The program will then calculate the calories burnt per activity, the total calorie burnt for the
week and the amount of weight lost during the week.
The amount of weight loss will be used to update the weight that was stored in the array and
calculate the person BMI . http://www.whathealth.com/bmi/formula.html
Activity Calorie Burnt Per pound per minute for
men (women are 1/6 less)
Walking .036
Running .095
Swimming .058
Hiking .058
Bicycling .044
 Calories burned per pound per minute (Bicycling – .044) x (times) your exact weight
(140 pounds) = (equals) total calories burned per minute (6.16 calories burned per
minute) x(times)minutes of activity (30 minutes) = (equals) 184.80 total calories
burned per activity.
 Women burn 1/6 less calories than Men.
 3500 calories = 1 pound of weight loss.
Author: Dexter Chin-Yan
Write a program that would do the following:
 Print a suitable heading and prompt for the required information
 Calculate the necessary required information and store in an Array(s)
o After members names, gender, weight in pounds and time spent in each
activity has been entered (10 Members) The program should calculate the
total calories burnt Total Calorie Burnt for the week and the amount of
weight loss (depending on whether it is a man or a woman.
o Calculate and display BMI and weight status based on the table above.
General Guidelines:
 Make use of appropriate messages to make you program as informative and user
friendly as possible, without being unnecessarily complex.
 Keep user interactions simple and instructions clear
 Use adequate documentation and proper indentation to clarify your program code
where necessary and improve layout
 Pay attention to good structure and use of programming constructs.
Evaluation
 Documentation and layout (spacing, indentation and commenting) 10 marks
 Proper layout of interface for input, output of information 10 marks
 Use of method to calculate, BMI, calories burnt per activity, and weight loss.
20 marks
 Creation and use of arrays to hold and processed information 20 marks
 Working program (Correctness, efficiency, user interaction)
