  B Physical Adaptations for Flight The internal body parts of all birds, including flightless ones, reflect the evolution of birds as flying creatures. Birds have lightweight skeletons in which many of themajor bones are hollow. A unique feature of birds is the furculum, or wishbone, which is comparable to the collarbones of humans, although in birds the left and rightportions are fused together. The furculum absorbs the shock of wing motion and acts as a spring to help birds breathe while they...

• Airplane.

  For example, the Anglo-French Concorde, a commercial supersonic aircraft, was generally limited to over-water routes, or to those over sparsely populated regions ofthe world. This limitation impacted the commercial viability of the Concorde, which ended its regular passenger service in October 2003. Designers today believe theycan help lessen the impact of sonic booms created by supersonic airliners but probably cannot eliminate them. One of the most difficult practical barriers to supersonic fl...

• Beetle - biology.

  cut, or crush prey. Beetles that consume nectar from flowers use tubelike mouthparts to suck up nectar like a primitive straw. C Thorax The thorax, the body region behind the head, consists of three segments that provide attachments for the legs and wings. Each segment of the thorax carries a pair oflegs. The middle segment also bears the stiff wing sheaths called elytra, and the hind segment holds the membranous hind wings. D Legs Beetles have six jointed legs, each leg with five parts. The f...

• Insect - biology.

  they almost always have six legs. In some insects, such as beetles, the legs are practically identical, but in other insects each pair is a slightly different shape. Still otherinsects have specialized leg structures. Examples are praying mantises, which have grasping and stabbing forelegs armed with lethal spines, and grasshoppers andfleas, which have large, muscular hind legs that catapult them into the air. Mole crickets’ front legs are modified for digging, and backswimmers have hind legs de...

• Butterflies and Moths - biology.

  The smallest butterflies are certain blues that have wingspans of a mere 0.7 cm (0.25 in). The largest are the female giant birdwings of Papua New Guinea, whichmeasure up to 30 cm (12 in) across. Moths range in size from tiny Microlepidoptera, several groups of small moths with wings no more than 0.16 cm (0.06 in) across, togiant silk moths, such as the atlas moth, which may exceed 30 cm (12 in) in wingspan. IV REPRODUCTION AND LIFE CYCLE Butterflies locate potential mates by sight, identifyin...

• Butterflies.

  When the change is complete, the adult butterfly splits the chrysalis. The insect unfolds its wings andpumps blood and air into them. It spreads out the wings until they dry and harden. The beautifulbutterfly then flies off to slurp nectar from flowers. Most butterflies live only one or two weeks. BUTTERFLY RELATIVES Butterflies are closely related to moths, another type of insect. One difference between butterflies andmoths is how their antennae look. Butterflies have knobs called clubs on the...

• Ant - biology.

  The workers of many ant species carry a stinger within the hind end of the gaster. These ants use the stinger to defend against their enemies. In some species, workerants lack a stinger but use the tip of their gaster to squirt or dab poison at other small animals and when fighting battles with other ants, fending off predators, or killinginsects or other animals that they use as food. III PHYSIOLOGY Ants have a rigid, external skeleton called an exoskeleton that gives the soft, inner body its...

There are two kinds of metamorphosis, called incompleteand complete. Dragonflies, grasshoppers, and crickets are some insects that go through incomplete metamorphosis asthey grow up. The young insects are called nymphs or naiads. The young insect molts, or crawls out ofits exoskeleton, as it grows bigger. It grows a new, larger exoskeleton. Its body chan...

• Helicopter.

  naturally flaps down so as to increase lift. Flapping allows the differences in lift caused by uneven rotor tip speed to cancel out, producing a stable ride. Many helicoptersuse mechanical hinges with lubricated bearings, but some use flexible straps made of a composite material in order to reduce the required maintenance. Helicopters require different amounts of lift and thrust at different times during flight, because the aerodynamic forces acting on them change during hovering andacceleration...

• Messier Lifts the Curse.

  Swept up in the hype, the Rangers came out for game five at the Garden in a virtual sleepwalk. By the start of the third period they were down 3-0. New Yorkscratched back to level the score as Messier culminated the three-goal spurt with a wrist shot midway through the period. Vancouver then stunned the Rangers—andthe sellout crowd—by netting three quick goals to put the game far out of reach. Game six in Vancouver proved even more of a challenge for the Rangers. The team showed little will...

• Battle of Waterloo.

  In the meantime, Grouchy had failed to overtake Blücher's army. At about 10 PM on June 17, Grouchy's scouts informed him that the Prussians, instead of retreating east to Namur, had turned northwest, seeking apparently a juncture with Wellington. Grouchy's message of warning to Napoleon brought the reply, sent at 10 AM on June 18, that Grouchy should keep trying to make contact with the Prussians. Grouchy's pursuit was slovenly and unhurried, and he failed to locate the enemy. On the morning o...

  At the beginning of the 20th century the Democrats’ minority position among voters remained central to their existence. The Progressive split in Republican rankshelped elect Woodrow Wilson twice, but the entry of the United States into World War I ended that.

When hescored a minute later the game was delayed while the ice was cleared of missiles tossed by fans.” Richard's 1944 Stanley Cup performance established him ashockey's best player of the time...

• Duck - biology.

  from water. When ducks feed they push their tongue against the top of their mouth to squeeze water through the lamellae, leaving the food behind. Mergansers arefish-eating ducks with slender bills that are notched on the edges like the blade of a saw. These saw-toothed beaks help the ducks catch and hold their slippery prey. VI COURTSHIP AND REPRODUCTION Ducks form pairs long enough to mate, but most species find new mates each year. In a few species, including buffleheads and whistling ducks,...

• Eagle - biology.

  States, is a member of this group found only in North America. It is named for its snow-white head. However, the name bald does not refer to a lack of feathers but comes instead from an outdated word meaning marked with white, as in piebald. The adult bald eagle is blackish brown, with a white head and tail. Its bill, legs, and feet are bright yellow. The bill, which is longer and heavier than the gray bill of golden eagles, is useful for piercing the skin of fish. Bald eagles vary in size....

  they didn't want to surrender the historic point. New York goalie Ed Giacomin was in fine form. Esposito missed on his first ten shots of the night. One clanked offthe goal post, drawing a chorus of “oohs” and “ahhs” from the crowd. Finally, in the second period, Esposito beat Giacomin and right wing Bob Nevin to ring up point number 98. It was his 38th goal of the season. Later in the gameEsposito notched his 99th point on an assist to Bobby Orr. Obviously keyed up to break the record, Espo...

A drupe develops from an ovary with a single carpel and is characterized by an edible exocarp and mesocarp and an inedible, hard endocarp, or pit that encloses asingle seed. Cherries, peaches, apricots, and plums are examples of drupes. Almonds also are classified as drupes, but in a...

  tomb bat has rather small ears. The shapes of bat ears are extremely varied. The wide ears of the Australian false vampire bat meet above the head and are fused.Many bats are able to turn their ears in the direction of faint noises. Bat hearing and its use in echolocation are highly developed. Some bats have large, conspicuous eyes, while others may have small beady eyes. This variation suggests that vision plays different roles in the lives of various species.Despite the familiar expression, 'b...

The original Saint Peter's Basilica in Rome, replaced bythe present church during the Renaissance, was a huge processional basilica with projecting wings—transepts—forming a Latin cross in plan. The domed, centralizedform persisted in the Byzantine and Slavic East, where medieval churches, small in scale, often took the form of five domes arranged on a Greek cross plan.
