A chordate is an animal constituting the phylum Chordata. During some period of their life cycle, chordates possess a notochord, a dorsal nerve cord, pharyngeal slits, an endostyle, and a post-anal tail: these five anatomical features define this phylum. Chordates are also bilaterally symmetric; and have a coelom, metameric segmentation, and a circulatory system.
N,N-Dimethyltryptamine is a chemical substance that occurs in many plants and animals and which is both a derivative and a structural analog of tryptamine. It can be consumed as a psychedelic drug and has historically been prepared by various cultures for ritual purposes as an entheogen. Rick Strassman labeled it "the spirit molecule". DMT is illegal in most countries.
Ecology is the branch of biology which studies the interactions among organisms and their environment. Objects of study include interactions of organisms with each other and with abiotic components of their environment. Topics of interest include the biodiversity, distribution, biomass, and populations of organisms, as well as cooperation and competition within and between species. Ecosystems are dynamically interacting systems of organisms, the communities they make up, and the non-living components of their environment. Ecosystem processes, such as primary production, pedogenesis, nutrient cycling, and niche construction, regulate the flux of energy and matter through an environment. These processes are sustained by organisms with specific life history traits. Biodiversity means the varieties of species, genes, and ecosystems, enhances certain ecosystem services.
The joule is a derived unit of energy in the International System of Units. It is equal to the energy transferred to an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre. It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule (1818–1889).
The tiger is the largest species among the Felidae and classified in the genus Panthera. It is most recognizable for its dark vertical stripes on reddish-orange fur with a lighter underside. It is an apex predator, primarily preying on ungulates such as deer and bovids. It is territorial and generally a solitary but social predator, requiring large contiguous areas of habitat, which support its requirements for prey and rearing of its offspring. Tiger cubs stay with their mother for about two years, before they become independent and leave their mother's home range to establish their own.
In probability theory and statistics, variance is the expectation of the squared deviation of a random variable from its mean. Informally, it measures how far a set of (random) numbers are spread out from their average value. Variance has a central role in statistics, where some ideas that use it include descriptive statistics, statistical inference, hypothesis testing, goodness of fit, and Monte Carlo sampling. Variance is an important tool in the sciences, where statistical analysis of data is common. The variance is the square of the standard deviation, the second central moment of a distribution, and the covariance of the random variable with itself, and it is often represented by , , or .
Electrical resistivity is a fundamental property of a material that quantifies how strongly that material opposes the flow of electric current. A low resistivity indicates a material that readily allows the flow of electric current. Resistivity is commonly represented by the Greek letter ρ (rho). The SI unit of electrical resistivity is the ohm-metre (Ω⋅m). As an example, if a 1 m × 1 m × 1 m solid cube of material has sheet contacts on two opposite faces, and the resistance between these contacts is 1 Ω, then the resistivity of the material is 1 Ω⋅m.

The O. J. Simpson murder case was a criminal trial held at the Los Angeles County Superior Court. Former National Football League (NFL) player, broadcaster, and actor O. J. Simpson was tried on two counts of murder for the June 12, 1994, deaths of his ex-wife, Nicole Brown Simpson, and her friend, Ron Goldman. On the morning of June 13, 1994, they were found stabbed to death outside Brown's condominium in the Brentwood area of Los Angeles. Simpson was a person of interest in their murders. He did not turn himself in, and on June 17 he became the object of a low-speed pursuit in a white 1993 Ford Bronco SUV owned and driven by Al Cowlings. TV stations interrupted coverage of the 1994 NBA Finals to broadcast the incident live. It was watched by an estimated audience of 95 million people. The pursuit, arrest, and trial were among the most widely publicized events in American history. The trial, often characterized as the trial of the century because of its international publicity similar to that of Sacco and Vanzetti and the Lindbergh kidnapping, spanned eleven months, from the jury's swearing-in on November 9, 1994. Opening statements were made on January 24, 1995, and the verdict was announced on October 3, 1995, when Simpson was acquitted on both counts of murder. Following his acquittal, no additional arrests or convictions related to the murders have been made. According to the newspaper USA Today, the case has been described as the "most publicized" criminal trial in history.

Mollusca is the second largest phylum of invertebrate animals. The members are known as molluscs or mollusks. Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species.
An arthropod is an invertebrate animal having an exoskeleton, a segmented body, and paired jointed appendages. Arthropods form the phylum Euarthropoda, which includes insects, arachnids, myriapods, and crustaceans. The term Arthropoda as originally proposed refers to a proposed grouping of Euarthropods and the phylum Onychophora. Arthropods are characterized by their jointed limbs and cuticle made of chitin, often mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. The rigid cuticle inhibits growth, so arthropods replace it periodically by moulting. Arthopods are bilaterally symmetrical and their body possesses an external skeleton. Some species have wings.
