  • It isan adaptation of some organs and tissues to do a specific function. • Ex: • Secreting sweat in humans in case of high temperature. • Secreting poison in snakes.
• 6.
  • It isan adaptation in the activity of some animals in different times of the daylight. • Ex: • Birds migration at certain times of the year • Activity of birds during the daylight and bats at night

  • mammals’ limbswere modified in many shapes and forms to suit the required ways of movement • Such As: • Walking, Flying, Swimming, Climbing And Diving.

  The type of adaptation Theaim of modification The modification in its limbs The mammals Structural adaptation To perform the function of swimming and diving in water. The two forelimbs of whales, dolphins and sea lion are modified to become paddles (fin-like structure) Whale structural adaptation To perform the function of flying. The two forelimbs are modified into two wing-like structures Bat Structural adaptation To perform the function of running on the rocky soil. Its limbs are modified To end with a strong hoof. Horse Structural adaptation To enable it to climb trees and catch things. The bones of the forelimbs and fingers are elongated. Monkey and gorilla

  The type of adaptation Themodification of its beak and legThe bird Structural adaptation * Beaks Strong and sharp crooked beaks to tear the prey’s flesh. * Legs Four fingers ending with strong and sharp claws, three anterior (front) fingers and one posterior (back) bendable to firm pouncing the prey. Birds which feed on meat (Predatory birds).(e.g. hawks and vultures) Structural adaptation * Beaks: Long thin beaks to pick up worms and snails. * Legs : Long thin legs ending in thin fingers to walk in the existence of water. Birds that feed on shallow water worms and snails. (e.g. Heron and hoopoe) Structural adaptation * Beaks Wide indented beaks in the two sides to help them filter the food from water. * Legs: Palm legs to help in swimming. Birds which feed on mosses and fish (Water birds) e.g. ducks and geese.

  • Insectivorous plants: •They are self-feeding (autotrophic) green plants because they can perform photosynthesis process so, they can make carbohydrates. • They can’t make proteins because they can’t absorb the nitrogenous substances needed to make proteins from the soil. • Some parts of these plants are adapted and modified to pounce (capture) and digest the insects, then absorb the nitrogenous substance that their bodies need.
