They also include comments on graphs and fully worked examples where applicable. The document is intended to help teachers and candidates understand the standard expected and as an aid for exam preparation and success.
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. Twenty respondents of varying ages, genders, education levels and employment statuses anonymously answered 16 questions about their gambling behaviors, preferences, expenditures and opinions. The questionnaires aimed to determine how common gambling is and suggest alternatives to address its growth.
The document discusses a student's social studies research project on alcohol abuse among 5th form students at their school. It outlines the research tasks which include: 1) determining the levels of alcohol abuse, 2) explaining why this topic was selected after reading a newspaper article about secondary student alcohol use, and 3) using a questionnaire method to collect data from students because it allows for easy yet confidential collection of information. It then provides the questionnaire to be administered which includes questions about student demographics, alcohol use behaviors, influences, and potential solutions.
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.
This document provides information on excretion in humans and other organisms. It discusses the key organs and processes involved in excretion in the human body, including the lungs, skin, and kidneys. In the kidneys, glomerular filtration occurs, along with reabsorption of useful substances and production of urine. The liver is described as having many functions including detoxification and producing urea from excess proteins. Excretion in plants, fish, and amoebas is also summarized, noting their various adaptations for osmoregulation.
The document is a cover letter and questionnaire for a geography student's field study on factors affecting banana production in Richmond, St. Vincent. The student, Leroy Walker, is conducting the study for a high school geography SBA (School-Based Assessment) in order to gain marks for their CXC/CSEC exam. The cover letter introduces the student and their study topic, and asks recipients to support their research by filling out the attached 16 question questionnaire about banana farming. The questionnaire asks farmers about demographics, crop details, diseases affecting production, storage issues, financial support, and suggestions for improving banana cultivation.
The document summarizes a geography student's research project on factors affecting banana production in Richmond, St. Vincent. The student conducted a questionnaire with 20 banana farmers to investigate factors like diseases, finances, and government assistance. Key findings include: most farmers were over 27 years old with primary education; the most cited disease was Black Sigatoka but some farmers lacked knowledge of disease dangers; many farmers lacked sufficient finances but felt government assistance for disease control was limited; suggested solutions included more effective disease control, extension officers, transportation assistance, and credit/attention for farmers.
This document provides information on banana production in St. Vincent and the Grenadines. It discusses the history of banana exports from the region and outlines the key steps in banana farming: planting, tending, harvesting, as well as common problems and solutions. The problems discussed include diseases like moko and leaf spot, nematodes, and slugs/snails. Solutions involve practices like sanitation, use of chemicals, and applying baits/pesticides. The overall goal is to produce high quality export fruit through effective farm management.
Cxc past questions and answers – principles of businessleroy walker
The document provides discussion and guidelines for answering past CXC Principles of Business exam questions. It includes sample questions on topics like economic systems, types of business organizations, contracts, leadership styles, entrepreneurship, and migration. 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.
