An android is a humanoid robot or other artificial being often made from a flesh-like material.

A definition of music endeavors to give an accurate and concise explanation of music's basic attributes or essential nature and it involves a process of defining what is meant by the term music. Many authorities have suggested definitions, but defining music turns out to be more difficult than might first be imagined, and there is ongoing debate. A number of explanations start with the notion of music as organized sound, but they also highlight that this is perhaps too broad a definition and cite examples of organized sound that are not defined as music, such as human speech and sounds found in both natural and industrial environments. The problem of defining music is further complicated by the influence of culture in music cognition.
Apoplexy is rupture of an internal organ and the accompanying symptoms. The term formerly referred to what is called a hemorrhagic stroke, which is a ruptured blood vessel in the brain. Modern health care professionals do not use the term, but instead specify the anatomic location of the bleeding, such as cerebral, ovarian or pituitary.
A body of water or waterbody is any significant accumulation of water on the surface of Earth or another planet. The term most often refers to oceans, seas, and lakes, but it includes smaller pools of water such as ponds, wetlands, or more rarely, puddles. A body of water does not have to be still or contained; rivers, streams, canals, and other geographical features where water moves from one place to another are also considered bodies of water.
Dog communication is the transfer of information between dogs, as well as between dogs and humans. Behaviors associated with dog communication are categorized into visual and vocal. Visual communication includes mouth shape and head position, licking and sniffing, ear and tail positioning, eye gaze, facial expression, and body posture. Dog vocalizations, or auditory communication, can include barks, growls, howls, whines and whimpers, screams, pants and sighs. Dogs also communicate via gustatory communication, utilizing scent and pheromones.
The lips are a horizontal pair of soft appendages attached to the jaws and are the most visible part of the mouth of many animals, including humans. Vertebrate lips are soft, movable and serve to facilitate the ingestion of food and the articulation of sound and speech. Human lips are also a somatosensory organ, and can be an erogenous zone when used in kissing and other acts of intimacy.
Cats need to communicate for a variety of reasons, including to show happiness, to express anger, to solicit attention, and to observe potential prey; cats collaborate, play, and share resources with each other. When they communicate with humans, they do so to get what they need or want, such as food, water, attention, or play.
Growling is a low, guttural vocalization produced by animals as an aggressive warning but can also be found in other contexts such as playful behaviors or mating. Different animals will use growling in specific contexts as a form of communication. In humans, low or dull rumbling noises may also be emitted when they are discontent with something or they are angry, although this human sound is often termed "groaning".
Screaming is an extended vocal technique that is popular in "aggressive" music genres such as heavy metal, punk rock, and noise music and others. It is common in the more extreme subgenres of heavy metal, such as death and black metal as well as many other subgenres.
A death growl, or simply growl, is an extended vocal technique usually employed in extreme styles of music, particularly in death metal and other extreme subgenres of heavy metal music. Death growl vocals are often criticized for their difficulty to understand without a lyric sheet, but they contribute to death metal's abrasive style and often dark and obscene subject matter.

Depending on its location or certain characteristics, a stream may be referred to by a variety of local or regional names. Long, large streams are usually called rivers, while smaller, less voluminous and more intermittent streams are known as streamlets, brooks or creeks.
Fold change is a measure describing how much a quantity changes between an original and a subsequent measurement. It is defined as the ratio between the two quantities; for quantities A and B the fold change of B with respect to A is B/A. In other words, a change from 30 to 60 is defined as a fold-change of 2. This is also referred to as a "one fold increase". Similarly, a change from 30 to 15 is referred to as a "0.5-fold decrease". Fold change is often used when analysing multiple measurements of a biological system taken at different times as the change described by the ratio between the time points is easier to interpret than the difference.
The arts are a wide range of human practices of creative expression, storytelling, and cultural participation. They encompass multiple diverse and plural modes of thinking, doing, and being, in an extremely broad range of media. Both dynamic and a characteristically constant feature of human life, they have developed into innovative, stylized, and sometimes intricate forms. This is often achieved through sustained and deliberate study, training, and/or theorizing within a particular tradition, across generations, and even between civilizations. The arts are a vehicle through which human beings cultivate distinct social, cultural, and individual identities while transmitting values, impressions, judgements, ideas, visions, spiritual meanings, patterns of life, and experiences across time and space.
