Mammals are any vertebrates within the class Mammalia (/məˈmeɪli.ə/ from Latin mamma "breast"), a clade of endothermic amniotes distinguished from reptiles (including birds) by the possession of a neocortex (a region of the brain), hair, three middle ear bones and mammary glands. All female mammals nurse their young with milk, secreted from the mammary glands. Mammals include the largest animals on the planet, the great whales. The basic body type is a terrestrial quadruped, but some mammals are adapted for life at sea, in the air, in trees, underground or on two legs. The largest group of mammals, the placentals, have a placenta, which enables the feeding of the fetus during gestation. Mammals range in size from the 30–40 mm (1.2–1.6 in) bumblebee bat to the 30-meter (98 ft) blue whale. With the exception of the five species of monotreme (egg-laying mammals), all modern mammals give birth to live young. Most mammals, including the six most species-rich orders, belong to the placental group. The largest orders are the rodents, bats and Soricomorpha (shrews and allies). The next three biggest orders, depending on the biological classification scheme used, are the Primates (apes and monkeys), the Cetartiodactyla (whales and even-toed ungulates), and the Carnivora (cats, dogs, seals, and allies).

An exposition, in the most general sense, is an organized presentation and display of a selection of items. In practice, exhibitions usually occur within museums, galleries and exhibition halls, and World's fairs. Exhibitions can include many things such as art in both major museums and smaller galleries, interpretive exhibitions, natural history museums and history museums, and also varieties such as more commercially focused exhibitions and trade fairs.

Philately (/fɪˈlætəli/; fih-LAT-ə-lee) is the study of postage stamps and postal history. It also refers to the collection and appreciation of stamps and other philatelic products.While closely associated with stamp collecting and the study of postage, it is possible to be a philatelist without owning any stamps. For instance, the stamps being studied may be very rare or reside only in museums.

Лев (Panthera leo) — крупный представитель семейства кошачьих рода Panthera, обитающий в странах Африки к югу от Сахары и Индии. У него мускулистое тело с широкой грудью, короткая округлая голова, круглые уши и тёмный пучок волос на кончике хвоста. У него ярко выражен половой диморфизм: взрослые самцы крупнее самок и имеют густую гриву. Это социальный вид, образующий группы, называемые прайдами. Львиный прайд состоит из нескольких взрослых самцов, родственных самок и детёнышей. Группы львиц обычно охотятся вместе, охотясь в основном на средних и крупных копытных. Лев — высший и ключевой хищник.

Animals are multicellular, eukaryotic organisms of the kingdom Animalia (also called Metazoa). All animals are motile, meaning they can move spontaneously and independently, at some point in their lives. Their body plan eventually becomes fixed as they develop, although some undergo a process of metamorphosis later on in their lives. All animals are heterotrophs: they must ingest other organisms or their products for sustenance.
