biologist: A scientist concerned within the research of residing issues.
biology: The research of residing issues. The scientists who research them are generally known as biologists.
blue whale: A species of baleen whale (Balaenoptera musculus) that’s the largest animal ever recognized to have existed. They’ll develop to lengths of 30 meters (virtually 100 ft) and weigh as much as 170 metric tons.
cetaceans: The order of marine mammals that features whales, dolphins and porpoises. The baleen whales ( Mysticetes ) filter their meals from the water with large baleen plates. The remaining cetaceans ( Odontoceti ) embrace some 70 species of toothed animals that embrace beluga whales, narwhals, killer whales (a kind of dolphin) and porpoises.
colleague: Somebody who works with one other; a co-worker or staff member.
laptop mannequin: A program that runs on a pc that creates a mannequin, or simulation, of a real-world characteristic, phenomenon or occasion.
laptop program: A set of directions that a pc makes use of to carry out some evaluation or computation. The writing of those directions is named laptop programming.
dolphins: A very smart group of marine mammals that belong to the toothed-whale household. Members of this group embrace orcas (killer whales), pilot whales and bottlenose dolphins.
drag: A slowing power exerted by air or different fluid surrounding a transferring object. It entails friction. However not like easy friction, it will increase with an object’s velocity.
extinct: An adjective that describes a species for which there are not any residing members.
power: Some outdoors affect that may change the movement of a physique, maintain our bodies shut to at least one one other, or produce movement or stress in a stationary physique.
fossil: Any preserved stays or traces of historical life. There are numerous several types of fossils: The bones and different physique components of dinosaurs are referred to as “physique fossils.” Issues like footprints are referred to as “hint fossils.” Even specimens of dinosaur poop are fossils. The method of forming fossils is named fossilization.
humpback: A species of baleen whale (Megaptera novaeangliae), maybe finest recognized for its novel “songs” that journey nice distances underwater. Enormous animals, they will develop as much as greater than 15 meters (or round 50 ft) lengthy and weigh greater than 35 metric tons.
ichthyosaur: A sort of large marine reptile that appears just like a porpoise. It’s title means “fish lizard.” It was not associated to fish or marine mammals, nonetheless. And though not a dinosaur, it lived similtaneously dinosaurs.
mass: A quantity that reveals how a lot an object resists dashing up and slowing down — principally a measure of how a lot matter that object is made out of.
Mesozoic: An period in geologic historical past that contained three associated durations which grew to become famend for his or her massive reptiles: the Triassic (which spanned from 251 to 199.6 million years in the past), the Jurassic (which spanned from 199.6 to 145.5 million years in the past), and the Cretaceous (which spanned from 145.5 to 65.5 million years in the past).
Mesozoic Period: An interval of geologic time from about 252 million to round 66 million years in the past. Typically referred to as the Age of Reptiles, this period contains the Triassic, Jurassic and Cretaceous durations.
mannequin: A simulation of a real-world occasion (often utilizing a pc) that has been developed to foretell a number of seemingly outcomes. Or a person that’s meant to show how one thing would work in or look on others.
orca: The most important species of dolphin. The title of this black-and-white marine mammal, Orcinus orca, means killer whale.
plesiosaur: A sort of extinct marine reptile that lived similtaneously dinosaurs and is famous for having a really lengthy neck.
prospect: (n.) The vista (as in what’s in view) or the way forward for one thing (akin to whether or not it’s going to achieve success).
reptile: Chilly-blooded vertebrate animals, whose pores and skin is roofed with scales or attractive plates. Snakes, turtles, lizards and alligators are all reptiles.
resistance: (in physics) One thing that retains a bodily materials (akin to a block of wooden, circulation of water or air) from transferring freely, often as a result of it offers friction to impede its movement.
sea: An ocean (or area that’s a part of an ocean). In contrast to lakes and streams, seawater — or ocean water — is salty.
unit: (in measurements) A unit of measurement is a normal method of expressing a bodily amount. Models of measure present context for what numerical values characterize and so convey the magnitude of bodily properties. Examples embrace inches, kilograms, ohms, gauss, decibels, kelvins and nanoseconds.
digital: Being virtually like one thing. An object or idea that’s just about actual could be virtually true or actual — however not fairly. The time period usually is used to discuss with one thing that has been modeled by (or achieved by) a pc utilizing numbers, not by utilizing real-world components. So a digital motor could be one which may very well be seen on a pc display and examined by laptop programming (nevertheless it wouldn’t be a three-dimensional gadget made out of metallic). (in computing) Issues which can be carried out in or by way of digital processing and/or the web. As an example, a digital convention could also be the place folks attended by watching it over the web.
whale: A typical, however pretty imprecise, time period for a category of huge mammals that lives within the ocean. This group contains dolphins and porpoises.
