What Does Biology A Level Teach You?
What’s A level Biology about? … Topics you will learn about include: lifestyle, transport, genes and health, development, plants and the environment, the natural environment and species survival, energy, exercise and co-ordination, as well as practical biology and research skills
Filtrate refers to liquid which has passed through the process of filtration. In filtration, all fluids are strained. Larger particles are stuck in the straining media, while tinier particles as well as liquids pass through, becoming filtrate
Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration. The material that diffuses could be a solid, liquid or gas. ... One of the main characteristics of diffusion is the movement of molecules along the concentration gradient
Redi gained fame for his controlled experiments. One set of experiments refuted the popular notion of spontaneous generation—a belief that living organisms could arise from nonliving matter. Redi has been called the "father of modern parasitology" and the "founder of experimental biology"
The foundation of biology as it exists today is based on five basic principles. They are the cell theory, gene theory, evolution, homeostasis, and laws of thermodynamics
Properties of Life. All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing
Dinitrophenol (DNP) is an uncoupler, or has the ability to separate the flow of electrons and the pumping of H+ ions for ATP synthesis. This means that the energy from electron transfer cannot be used for ATP synthesis
Definition of arthropod : any of a phylum (Arthropoda) of invertebrate animals (such as insects, arachnids, and crustaceans) that have a segmented body and jointed appendages, a usually chitinous exoskeleton molted at intervals, and a dorsal anterior brain connected to a ventral chain of ganglia
A parasite is an organism that lives on or in a host organism and gets its food from or at the expense of its host
Symbiosis is a close relationship between two species in which at least one species benefits. ... There are three basic types of symbiosis: mutualism, commensalism, and parasitism
Depending upon their degree of intimacy, four types of associations may be recognized among organisms. The four types are: (1) association arising from similar requirements as to environment; (2) commensalism; (3) symbiosis; and (4) parasitism
