How would scientists determine that punctuated equilibrium occurred by examining the fossil record?
Contact [7]

The scientist can tell that punctured equilibrium has occurred if they have examined the fossil fuels and can see that one organism rapidly evolved different characteristics.

Answer: Option D

<u>Explanation:</u>

Punctured Equilibrium is an evolutionary theory which proposes that the species appearing in the fossil's record will show little evolutionary changes. In punctuated equilibrium, change occurs gradually, First very little change can be seen which later results in the occurrence of huge changes.

Such huge changes can be clearly seen by examining the fossil records.  Thus if there is any evolutionary changes seen in the fossil's record, the scientist can conclude the occurrence of punctuated equilibrium.

(a) Name two processes that remove carbon from the atmosphere: _____ (b) Name two processes that add carbon to the atmosphere: _
Vikentia [17]

The two processes that remove carbon dioxide from the atmosphere are photosynthesis and absorption. Respiration and volcanism, or the eruption of molten rock, are the two processes that provide carbon to the atmosphere.

carbon is removed from the atmosphere through photosynthesis and replaced with O2. O2 is removed from the atmosphere during respiration and replaced with carbon . These processes, however, are not in equilibrium. Not every organic substance oxidizes. Photosynthesis and metabolism are the two fundamental processes that take place during the natural carbon cycle. Plants consume carbon dioxide during photosynthesis to create oxygen, and they also make carbon dioxide during metabolism.
