7 0

Answer:

Over 95% of incoming ultraviolet radiation is absorbed in :

A. The Stratosphere.

Explanation:

  • Stratosphere is the second layer of the earth's atmosphere that lies next to the troposphere.
  • This layer experiences very little turbulence of air and is very significant because of the presence of Ozone layer in it.
  • The UV rays entering the Earth's atmosphere, photo dissociates ozone into O₂ and O. But these molecules quickly recombine to form ozone.Thus, stabilizing the concentration of ozone in the atmosphere.
  • During this photo dissociation UV radiations loses much of its energy. Thus, 95% of incoming Ultraviolet radiation gets absorbed in the Stratosphere.
  • Absorption of ozone UV radiation increases exponentially with the thickness of ozone layer.

Answer:

The pectoralis muscle moves the front limb inward and the transverse abdominal muscles moves the posterior limiting membrane up. The limbs are brought into the shell, pushing up on the lung, causing air to expel by the muscles contracting.

Whats are the pros and cons of a endoskeleton?
Softa [21]

Well, an endoskeleton is an internal skeleton, like humans have. Pro: Bones do not get broke as easily, since they are inside of the body. Bones that break also heal more quickly in an endoskeleton, since they have tissue and blood surrounding it and transferring nutrients. Con: The flesh can get easily damaged. There is no shedding with endoskeletons, so a new skeleton cannot be grown in the event of an injury.
