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.

Answer:
Explanation: When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared. When there is more volume and less surface area, diffusion takes longer and is less effective. ... this is actually why cells divide.
Explanation:
