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:
C
Explanation:
deer are alive and therefor biotic. As they graze they eat grass, walk on land and use oxygen, - all parts of the environment
PP- purple homozygote
pp- white homozygote
Pp- purple hetrozygote
If these flowers cross, we obtain heterozygote offsprings with a genotype: Pp (100% of them will be like this)
Now, if those offsprings cross with each other: Pp x Pp
results:
1/4 would be purple homozygote -> PP
1/4 would be white -> pp
2/4 would be purple heterozygotes -> Pp
Genotipic ratio: 3:1 (3 are purple; 1 is white)
Answer:
The box will move toward you with a force of 10N
Explanation:
If you and your friend are pushing the same box with the same amount of force, those two forces will balance each other out, and the box won't move. In the question, 20N will cancel each other out, and there will be 10N. Your friend is pushing the box with more force than you, so it will move toward you with the remaining force of 10N
