The following tests can determine the mineral in a rock specimen:
1. How does the rock crumble or split under pressure?
2. What is the texture of the rock?
3. Observing it under a magnifying lens.
4. Determine the color of the rock
Test 1 and 3 determines if the rock is granular and the types of grains in the rock. Test 3 also determines if the rock has layers hence sedimentary rock.
Determining whether color of the rock is dark or light also helps identify the mineral and type of rock.
No, because it still codes for valine in this case, but if another nucleotide was changed such as GCA it would code for alanine instead.
The raw material from which sedimentary rocks are formed is D. Weathered remains of other rocks.
