The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
The document describes an experiment to determine whether an ordinary six-sided die is biased. Students were split into groups and each group performed one of six experiments, throwing the die 120 times on different surfaces. The experiments varied whether the die was shaken in the hand, a Styrofoam cup, or glass cup before being thrown on a varnished or cloth table. The results were combined and frequencies of each face landing uppermost were recorded. Charts and calculations were used to compare results and probabilities across experiments to reach a conclusion on bias.
This project analyzed the fairness of a coin toss through a series of experiments. Data was collected by tossing a coin 50 times under different conditions and recording whether it landed heads or tails. The results found the probability of each side landing face up was close to the theoretical 50% probability, demonstrating a coin toss is generally unbiased. While some individual trials showed slightly more of one side, overall the differences were small. The conclusion is that a coin toss can be used as a fair way to make a random selection.

Valdes Pierre conducted a social studies project on gambling in Chateaubelair, St. Vincent and the Grenadines. Chateaubelair has high illiteracy and unemployment, so some residents resort to gambling. Valdes distributed printed questionnaires at four locations over four hours to collect data on gambling prevalence.

1. Small organisms rely on diffusion for transport as their large surface area to volume ratio allows gases and nutrients to reach cells via diffusion. Larger multicellular organisms have developed transport systems like circulatory systems using blood and vessels due to their smaller surface area to volume ratio making diffusion insufficient.
2. Plants have vascular bundles containing xylem and phloem for transport. Xylem transports water and minerals upwards from roots while phloem transports carbohydrates made in leaves to other plant parts.
3. The human circulatory system uses blood, heart, arteries, veins and capillaries to transport substances between lungs, tissues and organs. Blood contains red blood cells, white blood cells, platelets
1. Respiration is the process by which energy is released from food molecules through oxidation. It occurs through aerobic and anaerobic respiration. Aerobic respiration fully breaks down glucose and releases more energy, while anaerobic respiration occurs without oxygen and releases less energy.
2. The respiratory system includes the nose, throat, windpipe, lungs, and alveoli. Gas exchange occurs in the alveoli through diffusion. Breathing is the process of inhaling and exhaling that supplies the alveoli with oxygen and removes carbon dioxide.
3. Smoking has negative health effects and increases the risk of diseases like cancer, bronchitis, emphysema and heart disease due to chemicals like nicotine
Carbohydrates provide energy and are made up of sugars like glucose, fructose, starch and cellulose. They lack energy leads to lack of energy. Proteins are needed for growth, repair of tissues, enzymes and antibodies. They are made up of amino acids. Lipids provide long-term energy storage and insulation and are made up of fatty acids and glycerol. Vitamins and minerals are required in small amounts daily for bodily processes but cannot be stored if unused. A balanced diet with sufficient amounts of each food group is needed to prevent malnutrition as each group provides nutrients for specific tasks.

For each question, it lists the required parts and number of marks, then provides a discussion of how to approach answering each part. This includes defining key terms, listing examples for different parts of questions, and describing different concepts in detail. The goal is to help students understand how to structure their responses to earn full marks for past paper questions.
