Deoxyribonucleic acid (DNA) is a molecule that contains the genetic instructions for the development, functioning, and reproduction of all living organisms. DNA is made of two long, twisted strands that form a spiral shape, and it carries the hereditary information used to build and maintain an organism. Each segment of DNA, called a gene, provides instructions for making specific proteins that influence traits and manage various bodily functions. DNA is found in the cells of all living things and is passed from parents to children, directing growth and development.

Air conditioning is a system that cools and controls the temperature inside a house, car, or other enclosed space. It works by removing heat and moisture from the air, making the environment more comfortable, especially in hot weather. The system usually includes a compressor, a cooling unit, and fans that help distribute the cooled air. Some air conditioning systems also have heating functions, allowing them to regulate temperature year-round. They improve air quality by filtering dust and humidity, making indoor spaces more pleasant and easier to breathe in.

A university is an institution of higher education that offers a wide range of academic programs, including undergraduate, graduate, and sometimes professional degrees. Universities typically have multiple departments or faculties, each specializing in different fields of study. In addition to providing bachelor's degrees, universities offer advanced degrees such as master's and doctoral programs. Universities are also centers for research, where students and faculty conduct studies that contribute to the advancement of knowledge. Many universities have a larger student body and offer a broader array of extracurricular activities compared to colleges.

Science fiction is a genre of film, television, or literature that explores imaginative ideas based on science and future technology. It often includes elements such as advanced technology, space travel, time travel, or life from other planets. The stories are set in worlds different from our own, often involving creative scenarios and inventions that go beyond current scientific knowledge. The goal of science fiction is to entertain and provoke thought by presenting interesting and inventive ideas about the future or alternative realities.

Carbohydrates are one of the three main macronutrients, along with proteins and fats, that provide energy to the body. They are found in a wide variety of foods, including fruits, vegetables, grains, and dairy products. Carbohydrates are classified into three main types: sugars, starches, and fiber. Sugars are simple carbohydrates found in fruits, vegetables, and dairy products, as well as in processed foods like candy and soda. Starches are complex carbohydrates found in foods like potatoes, rice, bread, and pasta. Fiber, also a complex carbohydrate, is found in plant-based foods like fruits, vegetables, whole grains, and legumes, and it aids in digestion. Carbohydrates are broken down into glucose, which is used by the body's cells for energy, especially for the brain and muscles during physical activity. A balanced intake of carbohydrates is important for overall health, supporting functions like energy production, digestion, and nutrient absorption.
