Answer: I believe that the answer is D.
Explanation:
Answer:
hello your question has some missing information attached below is the missing information
<em>answer :</em>
New planktonic larvae species = 10 species
New Non-planktonic larvae species = 26 species
Explanation:
<u>calculate for the number of new species that form in each group </u>
From the question it can seen that 3 species were present before 60 mya in each set
hence to calculate for the number of new species that form in each group
= Total number of species - number of species present at the beginning of 60mya
<u>Group 1 ( New planktonic larvae species ) </u>
= 13 -3 = 10 species
<u>Group 2 ( New Non-planktonic larvae species )</u>
= 29 - 3 = 26 species
Answer: The three main types, or classes, of rock are sedimentary, metamorphic, and igneous.
Explanation:
The differences among them have to do with how they are formed.
The concept would be crystallization. As magma cools inside or outside of the earth it crystallizes into an igneous rock. Intrusive (formed inside crust) igneous rocks are typically more course grained and contain many different noticeable minerals (for example, granite). Extrusive (formed outside) igneous rocks are typically more porous and are more fine grained then intrusive rocks (example, obsidian).
