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.

When an animal confronts a "fight-or-flight" situation, the release of epinephrine promotes glycogen breakdown in the liver, hea
nika2105 [10]

Answer: and Explanation:

A.)The reason for the different products of glycogen breakdown in the two tissues is that glucose 6-phosphotase which is

a known enzyme that brings about hydrolysis of glucose 6-phosphate as a result of the creation of a phosphate group and free glucose is not available in heart and skeletal muscle, therefore,any glucose 6-phosphotase that is produced will just enters the glycolytic pathway and get converted to lactate through pyruvate, in the absence of Oxygen O2.

B) Whenever a situation involving fight or flight arises, the concentration of glycolytic precursors becomes high in order to prepare for muscular activity. Since the membrane is impermeable to any charged species, and at the same time glucose 6-phosphotase enzyme cannot be moved through the glucose transporter, then there cannot be a release of Phosphorylated intermediates from the cell. The blood glucose level must be maintained by the liver by releasing of glucose.

glucose that is later formed from glucose 6-phosphotase then enters the bloodstream.
