col1,col2 What is biology?,Biology is the study of living organisms and their interactions with the environment. What are the three main branches of biology?,"The three main branches of biology are botany, zoology, and microbiology." What is a cell?,A cell is the basic structural and functional unit of all living organisms. What is DNA?,"DNA, or deoxyribonucleic acid, is a molecule that carries the genetic instructions for the development, functioning, growth, and reproduction of all known organisms." What is photosynthesis?,Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll. What is respiration?,"Respiration is the process by which organisms exchange gases with their environment, typically taking in oxygen and releasing carbon dioxide." What is mitosis?,Mitosis is the process of cell division in which one cell divides into two identical daughter cells. What is meiosis?,Meiosis is the process of cell division that produces gametes (sex cells) with half the number of chromosomes as the parent cell. What is evolution?,"Evolution is the process of change in all forms of life over generations, resulting in the diversity of organisms we see today." What is a gene?,A gene is a segment of DNA that contains the instructions for building one or more molecules that help cells function. What is a species?,A species is a group of organisms that can interbreed to produce fertile offspring. What is an ecosystem?,"An ecosystem is a community of living organisms and their physical environment, interacting as a system." What is a food chain?,"A food chain is a linear sequence of organisms, where each organism is eaten by the next organism in the chain." What is a food web?,A food web is a complex network of interconnected food chains that shows the flow of energy and nutrients through an ecosystem. What is a producer?,"A producer, also known as an autotroph, is an organism that can produce its own food through photosynthesis or chemosynthesis." What is a consumer?,"A consumer, also known as a heterotroph, is an organism that obtains energy by consuming other organisms." What is a decomposer?,"A decomposer is an organism that breaks down dead organic matter, returning nutrients to the environment." What is a virus?,A virus is a microscopic infectious agent that can only replicate inside the cells of living organisms. What is genetic engineering?,Genetic engineering is the manipulation of an organism's genes to introduce new traits or modify existing ones. What is biotechnology?,Biotechnology is the use of living organisms or their products to create or modify products or processes for specific purposes.
