environment The envelope of gases surrounding Earth or another world.

carbon The chemical component having the atomic number 6. It is the physical basis of all life in the world. Carbon exists easily as graphite and diamond. It is a fundamental part of coal, limestone and petroleum, and can self-bonding, chemically, to form a huge variety of chemically, biologically and commercially essential particles.

cell The tiniest structural and practical system of an organism. Generally too little to see with the unaided eye, it includes a watery fluid surrounded by a membrane or wall. Depending upon their size, animals are made from anywhere from thousands to trillions of cells.

chromosome A single threadlike piece of coiled DNA discovered in a cell’s nucleus. A chromosome is typically X-shaped in animals and plants. Some sections of DNA in a chromosome are genes. Other sections of DNA in a chromosome are landing pads for proteins. The function of other sections of DNA in chromosomes is still not completely comprehended by researchers.

diet plan The foods and liquids consumed by an animal to offer the nutrition it requires to grow and keep health. (verb) To embrace a particular food-intake prepare for the function of managing body weight.

DNA( brief for deoxyribonucleic acid) A long, double-stranded and spiral-shaped particle inside the majority of living cells that brings hereditary directions. It is constructed on a foundation of phosphorus, oxygen, and carbon atoms. In all living things, from plants and animals to microorganisms, these directions inform cells which particles to make.

ecology A branch of biology that handles the relations of organisms to one another and to their physical environments. A researcher who operates in this field is called an ecologist.

hibernation A state of lack of exercise that some animals go into to conserve energy at particular seasons. Bears and bats, for instance, might hibernate through the winter season.

telomere A natural protective “cap” on completions of chromosomes, made by successions of a six-nucleotide series of chemicals. This chemical series is discovered just on completions of chromosomes. It’s referred to as TTAGGG, where each T represents a particle of thymine, each A is a particle of adenine and each G is a particle of guanine. With time, telomeres reduce as they cell they remain in copies itself. If the telomere length gets too brief, the cell stops dividing and passes away.

tissue Made from cells, it is any of the unique kinds of products that comprise animals, plants or fungis. Cells within a tissue work as a system to carry out a specific function in living organisms. Various organs of the body, for example, frequently are made from several kinds of tissues.
