Like the deep-sea forms, the cave fauna are rela­tively recent in origin and the adaptive changes undergone by them are mainly degenerative specialisations. The articulating processes of the vertebrae in the trunk region become reduced but become elon­gated in the tail region for the attachment of the tail muscles. In Cetacea the eyelids are absent and the nictitating membrane is present over the eye-ball. But in cursorial animals the digitigrade condition becomes more per­fected. Migration allows the animals to find better resources or evade threat. In an­other form, Ptychozoon, the patagia are pre­sent along the sides of the neck, body, tail and limbs.

This is because, during autumn, other trees shed their leaves, which means more sunlight reaches the forest floor. The long bones are conservative, but the digits together with the carpals or tarsals become very much elongated. Behavioral adaptations are special ways a particular organism behaves to survive in its natural habitat e. All living beings need to adapt to their environment to survive. The proximal ridges of the humerus are highly developed to give attachment to the powerful shoulder muscle. Examples include the blubber of a whale, the beak of a woodpecker, baleen of a humpback whale. Tissue and organs especially susceptible to atrophy include skeletal muscle, cardiac muscle, , and the.

The length of the flight can exceed 200 to 300 yards. Amongst the invertebrates, sponges, corals, hydroids, few echinoderms such as brittle-stars and stalked crinoids, tube-dwelling annelid worms, some brachiopods, cephalopods, some arthropods like the barnacles are some of the deep-sea forms. Number one is atrophy, hypertrophy, hyperplasia, and metaplasia. The process of developing adaptations occurs over many generations; it is a population phenomenon involving genetics and is generally a slow process. The feathers are called the remiges. Aquatic adaptation Aquatic adaptations are found in those and that live in water habitats: fresh water, brackish water, and sea water.

One of the characteristic features of grasslands is its wide open spaces. The adap­tations in permanent cave-animals are quite striking. Characteristics of the Low-Rainfall Desert: It is generally regarded as a vast stretch of drifting sand with the following physical conditions: i Low rainfall, ii Extreme temperature, iii Low water vapour in atmosphere resulted from exces­sive solar radiation, iv Increased air movement which results into sand and dust storms and v Poor vegetation excepting in rare cases, e. The presence of five digits is the usual occurrence in plantigrade animals. Amongst the possible modes of living in nature, the parasitic existence, although regarded to be a case of degeneration, is certainly a most specialised type of living and has great survival value. Pathologic hyperplasia is an abnormal increase in cell division. Take for example Muslims in our country.

But it can be said beyond any doubt that para­sitism is more of recent origin than the free-living forms since free-living forms must have existed before the parasites could obtain hosts to live. The physiolo­gical efficiency of respiration is increased by the development of air-sacs in birds and chameleon. Alter the level of personal assistance For learners who need extra support with some tasks, enlist helpers such as peers, a special educator, or a paraprofessional. However, the size of canine teeth is also related to overall body size such scaling is known as , as shown by large carnivores such as that have bigger canines than do small carnivores such as. In rare cases, small bony vestiges representing the pelvis and limbs may be seen buried deeply in the muscle. The wing-finger supports the entire anterior region of the patagium.

Specialized Mode of Excretion Birds and reptiles in the desert retain water as their metabolic wastes are excreted in the form of an insoluble white compound called uric acid. Both types of adaptations help organisms to survive long enough to have offspring. These are two different types of inactivity where the metabolic rate slows down so much that the animal can survive without eating or drinking anything. For example, your student can receive the same math worksheet as the rest of the class, but you can ask him to complete only the odd-numbered items. Other genera of flying fishes are Dactylpterus, Pantodon, and Pegasus. The dorsal fin is triangular in Ichthyosaur. Acquisition of a subcutaneous layer of fat blubber in aqua­tic mammals compensates the loss of hairs by helping in the retention of body heat.

In some Sirenea, the paired mammae are axillary and situated practically upon the posterior border of the flippers. During the Miocene Epoch, nearly 25 million years ago, the earliest giraffe ancestor was the size of a modern red deer. Another reason for this and many other adaptations is for evasion of predators. Learning to appreciate a different sense of humour. An example of physiologic hypertrophy is in skeletal muscle with sustained exercise. Structures are slightly altered in the ectoparasites but they become highly modified in endopara­sites.

Eyes: For security and for searching suitable place for shelter, acute vision is necessary. These limbs constitute the most effective digging machine. In Ornithorhynchus and Otariidae the hind-limbs act as equilibrators. In bird, it is keeled. The blossoms start off with direct sunlight, and if there is shade overpowering the area, the blossoms will physically grow toward the sunlight.

Structural adaptations The external structures of animals can also help them to better adapt to their environment. The cod-like forms Gadiformes have re­duced mouth and dentition. The femur is not stout as the humerus and the ridges are not so prominent. The patagia are rudimentary as their functions are taken over by the feathers. It is green in colour. Others are seen to possess powerful jaws. The salivary glands are absent or reduced in aquatic mammals.
