The half life is the time taken for the amount of a substance to become half of its original value. If we take the initial value to be 30 on the y-axis, the half of 30 is 15. We check the time at which the substance has reduced to 15 atoms and this is about 40 seconds. <span>40 seconds therefore, is your answer.</span>

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.

Luden [163]

If you make a punnet square out of this, there is no possibility to have a recessive trait because neither parents have it plus dominant is always going to overrule recessive traits.
