The answer is given below in detail.
Explanation:
When a smoker continues smoking for years, the lungs develops cancer. The lung cancer progresses in the following order:
- The cell lining of the bronchi thickens and forms callus.
- After this step, cilia are lost
- Cells with atypical nuclei starts to appear
- After this tumor is formed
- In the final step, metastasis occur.
The correct answer would be A. The agent of metamorphism that would cause for the overall composition of a rock to change would be hydrothermal solutions. These solutions contain mineral substances that are dissolved in the hot water. When in contact with a rock, the minerals may change the composition of the rock.
<span>Larger stars burn through their Hydrogen reserves faster, fusing Hydrogen into heavier Helium.
Also, to maintain their phenomenal heat, they have to do this to maintain internal pressure and therefore the fusion that powers them, they have to burn quickly to replace the excess heat they radiate away into outer space.
Currently our sun radiates away 4 Million Tonnes of mass every second, that only amounts to a miserly 0.0000001% of its entire mass. Imagine how much mass larger and larger stars lose every second.
The smallest stars, born at the red dwarf level can burn for trillions of years (at closest estimate). Compared with the Supergiant's, the big boys who were born in abundance during the birth of the universe burn out and explode in supernovae after only around 200 Million years. A whisper compared to the life of our Sun which is estimated to run out of fuel after at the ripe of age of 10 billion years.</span><span>
