Of the rest, many are gymnosperms or softwood trees; these include conifers, cycads, ginkgophytes and gnetales, which produce seeds which are not enclosed in fruits, but in open structures such as pine cones, and many have tough waxy leaves, such as pine needles. Most angiosperm trees are eudicots, the "true dicotyledons", so named ...

Anatomy. The medulla oblongata is one of the three parts of the brainstem, along with the midbrain and the pons. These three collaborating structures are located in front of the cerebellum at the base of the brain and connect to the spinal cord. 1 . Made up of both white and gray matter, the cone-shaped medulla oblongata is formed about 20 ... Metabolism (/ m ə ˈ t æ b ə l ɪ z ə m /, from Greek: μεταβολή metabolē, "change") is the set of life-sustaining chemical reactions in organisms.The three main purposes of metabolism are: the conversion of the energy in food to energy available to run cellular processes; the conversion of food to building blocks for proteins, lipids, nucleic acids, and some carbohydrates; and the ... The Blood-Testis Barrier . The blood-brain barrier is a basic anatomical concept, with implications for disease and treatment. This system protects the brain and makes it difficult for many toxins, drugs, and other substances to affect it. There is a similar barrier in the testes that is referred to as the blood-testis barrier.

Age structure diagram definition biology. Hair follicles [ 1] are tiny holes or pores in your skin. Their main function is to grow hair. The scalp of your head too has hair follicles. In biological terms, hair follicle looks like a tunnel-shaped structure situated in the epidermis (outer layer of the skin) [ 2 ]. A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea.

De novo design of proteins that can bind to novel and highly diverse user-defined small molecule ligands could have broad biomedical and synthetic biology applications. Because ligand binding site geometries need to be accommodated by protein backbone scaffolds at high accuracy, the diversity of scaffolds is a major limitation for designing new ligand binding functions. Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations.Another major theme is evolution, which explains the unity and diversity of life. The trachea is roughly 4 to 5 inches long and 1 inch in diameter. It starts just under the larynx (voice box) and runs down the center of the chest behind the sternum (breast bone) and in front of the esophagus. 1 . The trachea is connected to the larynx via a ring of cartilage known as the cricoid cartilage. Dr Michelle Rudden, from the University of York's Department of Biology, said: 'Solving the structure of this "BO enzyme" has allowed us to pinpoint the molecular step inside certain bacteria that ...
