(1)

Troposphere – This is the densest layer and where weather events occur

Stratosphere – This is where the ozone layer is found. Some high altitude aircraft cruise in this layer.

Mesosphere – Temperatures drop with altitude in this layer

Thermosphere – This is where most of the meteorites that enter the earth’s atmosphere burn up. This layer takes up most of the Uv and X-rays from the sun. Most satellites orbiting earth are in this layer

Exosphere – almost akin to space due to the thinness of the layer. Molecules in the layer often escape into space

(2)

A ‘pause’ is a transition between the above-mentioned distinct layers. The tropopause, for example, occurs between the troposphere and the stratosphere and the stratopause between the stratosphere and mesosphere and thermopause is found between thermosphere and exosphere.

(3)

A temperature inversion is a rise in temperatures with altitude in a layer in the atmosphere. One layer exhibiting temperature inversion is the stratosphere. This is due to the ozone layer that absorbs UV light. The upper ozone absorbs most of the UV light, than lower ozone, exciting the molecules and making the higher altitudes in the layer to be warmer.

(4)

The ozone layer protects life on earth from the high energy UV radiation from the sun. UV is capable of causing double-stranded break on DNA resulting in genetic mutations on organisms. Most of these would be lethal. The Ozone absorbs most of the UV before it reaches earth's surface. Ozone is formed when an oxygen molecule reacts with another oxygen atom to form an O₃. The oxygen atoms are made from the splitting of an oxygen molecule by UV light.

The activation of receptor tyrosine kinases is characterized by _____.
xxTIMURxx [149]

Answer:

dimerization and phosphorylation

Explanation:

Protein kinase receptors are simply saying receptors with associated kinases (usually tyrosine kinases).

Protein kinases are enzymes that have the ability to modulate other enzymes (or some other proteins) by adding the phosphate group. This is known as phosphorilation process. As a result of structural change, protein can change its activity (phosphorilation usually increase the activity).

Such receptors are involved in a many processes within an organism that are important for the cellular growth, differentiation, metabolism .
