Carapace A carapace is a dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods such as crustaceans and arachnids, as well as vertebrates such as turtles and tortoises.n arachnids, the carapace is formed by the fusion of prosomal tergites into a single plate which carries the eyes, ocularium, ozopores (a pair of openings of the scent gland of Opiliones) and diverse phaneres. In a few orders, such as Solifugae and Schizomida, the carapace may be subdivided.

Fitness (biology) Fitness is the quantitative representation of natural and sexual selection within evolutionary biology. It can be defined either with respect to a genotype or to a phenotype in a given environment. In either case, it describes individual reproductive success and is equal to the average contribution to the gene pool of the next generation that is made by individuals of the specified genotype or phenotype. The fitness of a genotype is manifested through its phenotype, which is also affected by the

Rostrum (anatomy) Invertebrates. 1  In crustaceans, the rostrum is the forward extension of the carapace in front of the eyes. 2  Among insects, the rostrum is the name for the piercing mouthparts of the order Hemiptera. 3  Gastropod molluscs have a rostrum or proboscis. 4  Cephalopod molluscs have hard beak-like mouthparts referred to as the rostrum.

- The cell (from Latin cella, meaning small room) is the basic structural, functional, and biological unit of all known living organisms. Cells are the smallest unit of life that can replicate independently, and are often called the building blocks of life. The study of cells is called cell biology. Cells consist of cytoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids. Organisms can be classified as unicellular (consisting of a single cell; including bacteria) or multicellular (including plants and animals).

Barnacle A barnacle is a type of arthropod constituting the infraclass Cirripedia in the subphylum Crustacea, and is hence related to crabs and lobsters. ring of plates surrounds the body, homologous with the carapace of other crustaceans. These consist of the rostrum, two lateral plates, two carinolaterals, and a carina. In sessile barnacles, the apex of the ring of plates is covered by an operculum, which may be recessed into the carapace.

mitochondrion (mī'tə-kŏn'drē-ən) Plural mitochondria. A structure in the cytoplasm of all cells except bacteria in which food molecules (sugars, fatty acids, and amino acids) are broken down in the presence of oxygen and converted to energy in the form of ATP. Mitochondria have an inner and outer membrane. The inner membrane has many twists and folds (called cristae), which increase the surface area available to proteins and their associative reactions. The inner membrane encloses a liquid containing DNA, RNA, small ribosomes, and solutes.

Carapace In crustaceans, the carapace is a part of the exoskeleton that covers the cephalothorax. The carapace functions as a protective cover over the cephalothorax. Where it projects forward beyond the eyes, this projection is called a rostrum.The carapace is calcified to varying degrees in different crustaceans.n arachnids, the carapace is formed by the fusion of prosomal tergites into a single plate which carries the eyes, ocularium, ozopores (a pair of openings of the scent gland of Opiliones) and diverse phaneres. In a few orders, such as Solifugae and Schizomida, the carapace may be subdivided.

How are living things adapted to their environments? In biology, an ecological niche refers to the overall role of a species in its environment. Most environments have many niches. If a niche is empty (no organisms are occupying it), new species are likely to evolve to occupy it.

What Is Conservation Biology? - Definition & Principles Ecology is the study of how organisms interact with their environment on a variety of levels. It is a diverse field that encompasses many different aspects of the environment and environmental relationships.rotection of a focal species includes learning about the behavior of the focal species, its habitat and resource requirements, what roles it fills in the ecosystem and how it is threatened by human activity.
