Which is not a flying adaptation of a bird? <\/span><\/p>

Streamlined body <\/span><\/p>","correct":false},{"option":"

Body covered with feathers<\/span><\/p>","correct":false},{"option":"

Forelimbs have strong <\/span><\/p>","correct":true},{"option":"

Body light in weight<\/span><\/p>","correct":false}],"solution":"

Answer:<\/strong> (C) Forelimbs have strong<\/p>\r\n

Explanation:<\/strong><\/p>\r\n

Birds have evolved a number of adaptations that enable them to fly. These adaptations include:<\/p>\r\n

    \r\n
  1. Hollow Bones:<\/strong> Birds have lightweight, hollow bones that reduce their overall body weight, making it easier for them to take off, fly, and stay airborne.<\/li>\r\n
  2. Feathers:<\/strong> Feathers provide the necessary lift and thrust for flight. The structure of the feathers is designed to maximize aerodynamic efficiency.<\/li>\r\n
  3. Wing Shape:<\/strong> The shape of a bird's wings is crucial for flight. Wings are typically curved on the top and flatter on the bottom, creating an airfoil shape that provides lift.<\/li>\r\n
  4. Powerful Flight Muscles:<\/strong> Birds have powerful pectoral muscles that provide the force needed to flap their wings.<\/li>\r\n
  5. Streamlined Body:<\/strong> A streamlined body shape reduces air resistance during flight.<\/li>\r\n
  6. Large Sternum (Keel):<\/strong> The large sternum provides an attachment point for the powerful flight muscles.<\/li>\r\n
  7. Efficient Respiratory System:<\/strong> Birds have a highly efficient respiratory system that provides the necessary oxygen to sustain flight.<\/li>\r\n<\/ol>","subject":"Biology"},"yoast_head":"\nWhich is not a flying adaptation of a bird?\u00a0\u00a0 -
