number is probably higher. They are found on every continent except Antarctica, in every habitat on the planet that contains insect-pollinated flowering plants. Bees are adapted for feeding on nectar and pollen, the former primarily as an energy source, and the latter primarily for protein and other nutrients. Most pollen is used as food for larvae. Bees have a long proboscis (a complex "tongue") that enables them to obtain the nectar from flowers. They have antennae almost universally made up of 13 segments in males and 12 in females, as is typical for the superfamily. Bees all have two pairs of wings, the hind pair being the smaller of the two; in a very few species, one sex or caste has relatively short wings that make flight difficult or impossible, but none is wingless. The best-known bee species is the European honey bee, which, as its name suggests, produces honey, as do a few other types of bee. Human management of this species is known as
what makes it the highest observation deck accessible to the public in the Europe. · The Eiffel Tower has 3 floors and 8 lifts/elevators. Consturction and Design · Work on the foundations started on 28 January 1887. · Those for the east and south legs were straightforward, but the west and north legs, being closer to the river Seine, were more complicated · The wrought iron of the Eiffel Tower weighs 7,300 tons, but the addition of lifts, shops and antennae have brought the total weight to 10,100 tons Construction and Design · When it was built, many were shocked by the tower's form. Eiffel was accused of trying to create something artistic with no regard to engineering. However, Eiffel and his team understood the importance of wind forces, and knew that if they were going to build the tallest structure in the world. · Equipping the tower with adequate and safe passenger lifts was a
töötasid? Nimeta töid. Alexander Calder lõi skulptuure, mis koosnesid peente varraste või traatide otsa kinnitatud erivärvilistest ja erineva suurusega elementidest. Need kinnitas ta laest rippuva või põrandalt tõusva varda otsa ja moodustas niiviisi nn. mobiili. Need olid hästi tasakaalustatud konstruktsioonid kus väiksemaid ja kergemaid elemente tasakaalustas teisel pool telge raskemast materjalist element. Väiksemgi tuuleõhk pani need liikuma. Tema teosed: "Antennae with Red and Blue Dots", "Fish Mobile", "Southern Cross" 8.Mis vahe on performanc'il ja happening'il? Happening' i eesmärk on vaatajat sokeerida, pakkuda elamust, üllatust ning tekitada protesti. Vaatajate reaktsioonid omakorda mõjutavad edasise etenduse kulgu. Üldjuhul toimub happening vaid ühe korra. Performance on juba rohkem plaanipärasem, publik selles üldiselt väga ei osale ning etenduse sõnum peitub eelkõige tegevuses. Performance'i puhul saab välja tuua ka mitmeid
Nad kaitsevad siseorganeid ja moodustavad jäsemete mehhaanilise toe. Putukate skleriidid ja lihased moodustavad lahutamatu terviku; kõikide liigutuste aluseks on skleriitide ja lihaste koostöö. Mitmekesisus putukate väliskujus põhineb välisskeleti erinevustel (oluline määramisel). 2. Putuka keha üldine välisehitus Putuka keha koosneb kolmest põhiosast: pea (caput), rindmik (thorax) ja tagakeha (abdomen). Pea (caput) külge kinnituvad putuka suuorganid e suised (trophi) ja tundlad (antennae), pea külgedel asetsevad liitsilmad (oculi) ning nende vahel võib olla kuni kolm lihtsilma (ocelli). Tugevasti sklerotiseerunud, täiskasvanud putukal ei ole segmentide piire. Kukal – occiput; kiirmik – vertex; laup – frons; näokilp – clypeus; ülahuul – labrum; põsk – gena; Ülalõug – mantibula; alalõug – maxilla; tundel – antennae; liitsilm; lihtsilm – ocellus. Rindmik koosneb kolmest lülist: ees-, kesk- ja tagarindmik (pro-, meso- ja metathorax). Igale
On ühed väga tavalised alamvähkide esindajad. Vesikirbud perekonnast Daphnia on enamasti väikesed, silmaga vaevu märgatavad, veekihis ujuvad loomad. Neile on iseloomulik külgedelt tugevasti kokkusurutud, ümarovaalne keha. Seda katab kitiinainest pearindliku kilp. Viimase varjus asub ka lühike ja hargi taolise jätkega lõppev tagakeha. Nagu enamikule veekihis elavatele loomadele iseloomulik on nende kehakatted läbipaistvad. Pea eesosas paiknevad tugevad tundlad (antennae), mis on muutunud liikumiselunditeks. Liikide arv: ligi 100 Kirjandus: - Selts Aerjalalised Copepoda Aerjalalised on vesikirpudega sama elupaika jagavad vähikesed. Tuntumad nendest on sõudikud perekond Cyclops. Need, vesikirbulistega mõõtmetelt sama suured vähikesed, erinevad viimastest oma sihvakama (tilgakujulise), tagasuunas aheneva keha poolest. Tagakeha lõpeb ka neil hargiga. Kõikidele emastele aerjalgsetele on iseloomulik munakobarate kandmine tagakeha külgedel
Mary not infrequently ordered changes in her nomenclators, which were much smaller and flimsier than the diplomatic ones. What neither Mary nor Babington knew was that, despite their elaborate precautions, their correspondence was being delivered to Walsingham and Phelippes as quickly as they wrote it. Gilbert Gifford was a double-agent, a ne'er-do-well who had offered his services to Walsingham. Walsingham, seeing an unparalleled opportunity to insinuate his antennae into Mary's circles, employed Gifford to turn over to him all Mary's letters, which he copied and then passed on. It included the two-year backlog entrusted to Gifford by the French ambassador, and the rapidly growing volume of traffic generated by Babington's festering plot. These enciphered missives were being solved by Phelippes almost as quickly as he got his hands on them. As the conspiracy reached a crescendo of preparation in the middle of July, he was
