Explain how soaring and gliding birds use their air currents in their flight
ira [324]

Soaring and gliding birds like eagle, vulture, albatross, sea gulls etc are efficiently adapted to utilize the air currents in their flight.

Explanation:

The soaring flight and gliding movements are special adaptation developed by birds to meet the challenge of increasing turbulent air current.

Birds have the extraordinary skill of flying smoothly and effortlessly even at very high altitudes  

Birds soar by using thermal and dynamic soaring techniques.

Gliding movements help the birds to deflect the wind downward which helps to lift their bodies in the air. They do not flap their wings during gliding but just dive straight into the air which helps to increase their speed.

The adaptation of the bird’s structure with very light but strong bones on their wings helps to soar and glide in the air.

The condition Marfan syndrome results from the production of abnormal elastin, the main protein component of elastic fibers. Pre
Marina86 [1]

Answer:

Elastic fibers are made of elastin and microfibrils, that are elastic protein structures. The proteins can be stretched and resume normal shape. These fibers are found in parts of the body such as arteries, skin, lungs, connective tissue and heart that require some stretching. Marfan syndrome affects the elastic connective tissues causing symptoms like dilation of the aorta that doesn't resume normal lumen diameter (aortic aneurysm), and curving of the spine (scoliosis).

The lungs are unable to stretch and resume shape normally and this affects the respiratory system. The subjects will suffer from shortness of breath, wheezing and chest pain.

The sheath/endoneurium of neurons is connective tissue. This part of a neuron allows signals to travel effeciently along the axon of the neuron. This means that a person with Mafran syndrome has a slower response to stimuli that ordinary persons.
