Please help 7.
Apply: Look at the DNA sequence at right. Describe the frog's phenotype.
8. Interpret: Click New to get a new population. Again, determine which codons
code for which traits. Compare the results with the table above. How do the codons
used to code for skin color, eye color, and spots in this new population of frogs
compare to the first population you tested?
9. Explain: suppose a Biologist found a rare frog I wanted to determine which species it belongs to. How could a biologist used a DNA sequence of a frog to accomplish this task?
10. Extend your thinking: What other applications of DNA sequence can you think of?

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.

the answer u all are looking for is 4000000000000000000000 million years.
