"Biphenyl" Natural Recordings by Native Speakers
Biphenyl is a type of organic compound consisting of two phenyl rings linked by a single bond. It is also known as diphenyl or benzophenone. Biphenyl is a colorless, crystalline solid with a sweet, phenolic odor. It is commonly used as a precursor in the production of other chemicals and pharmaceuticals.
Bipedalism is the ability to move on two legs or feet, typically as a primary mode of locomotion. It is a characteristic that distinguishes humans and some other primates from quadrupedal mammals that walk on four legs. The development of bipedalism is believed to have played a crucial role in the evolution of humans, as it allowed for more efficient walking, running, and carrying of loads, and potentially also opened up new opportunities for communication, social interaction, and tool use.
Bipedality refers to the ability to walk on two legs. It is a characteristic shared by many mammals, including humans, chimpanzees, and some species of monkeys and apes. This mode of locomotion provides a number of advantages, including increased mobility, improved balance, and enhanced vision. In humans, bipedality is thought to have developed as an adaptation to facilitate hunting, gathering, and tool use, and it has played a key role in shaping the evolution of the human species.
Adverbially, "bipedally" means "on two feet" or "walking on two legs". It is often used to describe humans and some animals that have the ability to stand and move around on two legs.
Bipeds are animals or humans that move on two legs. The term typically refers to organisms that have evolved to stand upright on two legs, such as humans, birds, and some dinosaurs.
Bipennate refers to a shape or structure that is divided into two parts, often of roughly equal size, and joined together at a central point or axis. This term is commonly used in biology to describe the shape of certain leaves, feathers, or antlers.
A bipennis is a historical term that refers to a type of ancient Greek and Roman sword with a long, double-edged blade and a distinctive shape. The name "bipennis" comes from the Latin words "bi", meaning "two", and "penne", meaning "feather" or "quill", likely due to the shape of the sword's crossbar.
Biphasic refers to something that has two distinct phases or stages. In medicine, it can describe a medication or treatment that has a biphasic effect, meaning it has two distinct effects or actions on the body at different times. For example, an insulin medication may have a rapid-acting phase that quickly lowers blood sugar levels, followed by a longer-lasting phase that helps maintain normal blood sugar levels over a longer period. In other contexts, biphasic can refer to something that has a dual purpose or function, such as a biphasic process in manufacturing that involves two separate steps or phases.
Biphenotypic refers to the phenomenon where a cell or an organism displays characteristics of two distinct cell types or phenotypes, often as a result of an abnormal development or a disease state. For example, some cancer cells can be biphenotypic, exhibiting features of both their original cell type and an alternative cell type that they have acquired during tumorigenesis.
Biphenyls are a class of organic compounds that contain a phenyl ring (a ring with six carbon atoms) and a biphenyl unit, which is a type of aromatic compound. The term "biphenyl" can also refer specifically to 1,1'-biphenyl, which is a molecule consisting of two phenyl rings linked together through a carbon-carbon bond. Biphenyls are used in a variety of applications, including in the production of plastics, dyes, and pharmaceuticals.
Biphonemic refers to the organization of a language's phonemes (distinct sounds) into pairs that have a specific relationship, such as being either identical, complementary, or in a relationship of assimilation.
