a British clock maker, developed the first chronometer that kept accurate time at sea. ii. Eukaryotes (/ j u k r i o t s,- t s /) are organisms whose cells have a nucleus enclosed within a nuclear envelope. Arthropod exoskeletons are made of cuticle, a non-cellular material secreted by the epidermis. Gnetophyta (/ n t f t , n t o f a t /) is a division of plants (alternatively considered the order Gnetales), grouped within the gymnosperms (which also includes conifers, cycads, and ginkgos), that consists of some 70 species across the three relict genera: Gnetum (family Gnetaceae), Welwitschia (family Welwitschiaceae), and Ephedra (family Ephedraceae). Hox genes, a subset of homeobox genes, are a group of related genes that specify regions of the body plan of an embryo along the head-tail axis of animals. These are the first organism to have a true coelom. Known from fossils as old as the Cretaceous, the requiem sharks did not significantly radiate before the Eocene (when
Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to Arthropoda. In biology, taxonomy (from Ancient Greek () 'arrangement', and - () 'method') is the scientific study of naming, defining (circumscribing) and classifying groups of biological organisms based on shared characteristics. A protist (/ p r o t s t /) is any eukaryotic organism (that is, an organism whose cells contain a cell nucleus) that is not an animal, plant, or fungus.While it is likely that protists share a common ancestor (the last eukaryotic common ancestor), the exclusion of other eukaryotes means that protists do not form a natural group, or clade. Among the carcharhinids, the genus Carcharhinus has the largest number of living species, namely, at least 35.

Know more: Annelida. (from Marine invertebrates) On Jan. 28, 1896, Arnold was spotted going four times the speed limit in his 19th-century Benzbut since the speed limit at the time was just two miles per hour, that meant he was not going too Annelida: segmented worms like earthworms that illustrate the first complete and contained digestive system Arthropoda : insects, crustaceans, and spiders that have hardened outside exoskeletons Know more: Annelida. Leech's scientific name is Hirudinaria granulosa. They appear in the fossil record 571 million to 541 million years ago. According to Guinness World Records, the first person to be charged with speeding was Walter Arnold of the English village of Paddock Wood, Kent. They are among the flattest, smoothest, and least explored regions on Earth.
In the northern hemisphere, stars appear to rotate around the North Star (Fig. Wiwaxia fossils mainly isolated scales, but sometimes complete, articulated fossils are known from early Cambrian and middle Cambrian fossil deposits across the globe. Odontogriphus was apparently a very rare species, accounting for less than 0.5% of the individual organisms found in the same fossil beds. It is a segmented parasitic worm. Like all bryophytes, the dominant life phase of a hornwort is the haploid gametophyte.This stage usually grows as a thin rosette or ribbon-like thallus between one and five centimeters in diameter. Solution: Form the four given options the correct answer is (c) Annelida. Most of the fossils consist of two parts of a split block of rock, the upper part giving a "casting" of the animal's upper surface and the lower giving one of its underside.Odontogriphus was a flat-bodied animal ranging from 3.3 millimetres (0.13 in) to Urochordata (Greek: Uro tail; chorde cord) is one of the subphyla of the Phylum Chordata and exhibits the following characteristics: i. ii.

Gnetophyta (/ n t f t , n t o f a t /) is a division of plants (alternatively considered the order Gnetales), grouped within the gymnosperms (which also includes conifers, cycads, and ginkgos), that consists of some 70 species across the three relict genera: Gnetum (family Gnetaceae), Welwitschia (family Welwitschiaceae), and Ephedra (family Ephedraceae). The origin of the eukaryotic flagellum (or cilium, terms referring to variants of essentially the same organelle) predates the radiation of known eukaryotes from a last common ancestor over a billion years ago (Roger and Simpson 2009).The presence of whip-like flagella or short, hair-like arrays of many cilia protruding from cell surfaces is a striking visual feature of iv. Later two further main ranks were introduced, making the sequence kingdom, phylum or division, class, order, Festering Skies is DLC 3. For example, Hox genes in insects specify which appendages form on a segment (for

The nature of the first bilaterian is a matter of debate. They are poikilothermic animals, and the body is divisible into head, neck, trunk and tail. 8. The duration of the exam will be 90 minutes. The first domesticate was the wolf (Canis lupus) at least 15,000 years ago.The Younger Dryas that The domestication of animals and plants was triggered by the climatic and environmental changes that occurred after the peak of the Last Glacial Maximum around 21,000 years ago and which continue to this present day. The RRB Group D The earliest indication that whale carcasses could host specialized animal communities occurred in 1854 when a new mussel species was extracted from a piece of floating whale blubber.
