The Cambrian explosion was a period at the Pre-Cambrian boundary of the geologic time scale at 542 Ma. At this boundary, the fossil record shows that animals suddenly appeared in a dramatic radiation of life. A radiation is the relatively rapid development of new types of organisms that derive from a common ancestor. The Cambrian explosion is important because it marks the origination of all major animal groups called phyla.
The only answer that could be considered an advantage is C. Increasing the amount of crops harvested.
<h3><u>Answer;</u></h3>
<em>A. continental-oceanic convergent</em>
<h3><u>Explanation;</u></h3>
- <em><u>A convergent boundary</u></em> is a type of boundary where two plates collide and push against one another.
- <em><u>A continental-oceanic convergent</u></em> is a type of convergent boundary that occurs as a result of <em><u>subduction.</u></em> <em><u>Subduction occurs where a continental plate collide thus resulting to the oceanic plate being pushed underneath the continental plate</u></em> into the mantle since the oceanic plates are much thinner.
- The result is that <em><u>the oceanic plates melts into hot magma which that burns its way up through the continental plate</u></em> forming a volcano and also causing earth quakes.
The answer would be C. protista and plants because they are the only ones that contain chloroplasts which start the photosynthesis cycle
