Correct answer is B.
Explanation:
In their nucleus cells contain DNA. The DNA has information about size, shape and function of each cell. When the cell reaches it's full size it stops growing and starts doing whatever it's function is. If more cells are needed then the cell replicates. This explanation excludes answers A and C.
Male and female sexual cells are used to conceive a baby. These cells combine to form a new type of cells. In the first few weeks all types of cells are created. Then the creation of new types of cells stops and existing cells multiply in order to achieve needed number of cells. This explanation excludes answer D.
When we compare an adult person and a baby we can see that, for example, an adult has bigger bones than a baby. This was result of increasing number of existing types of cells without creating any new type.
Answer:
1. Applying <u>the principle of original horizontality</u> -indicates that layers were repositioned from a flat-lying orientation.
2. Magma intrudes into layers of sedimentary rock and displaces them. We can deduce that the intruded magma that crystallizes is younger than the surrounding sedimentary layers by applying <u>the principle of crosscutting relationships</u>.
3. While visiting the Grand Canyon, you are amazed by the depth of layers of sedimentary rock before you, <u>the law of superposition</u>-- is evident here where progressively younger layers have formed over time and are stacked upon each other.
4. A fault cuts through layers of limestone, sandstone, and conglomerate. The surrounding layers must be <u>older</u> than the fault.
5. A mass of granite has inclusions of surrounding sandstone. The sandstone and surrounding layers show evidence of uplift over time. The granite must be <u>younger</u> than the sand deposits.
Two ways in which the proximity to water has affected Western Europe's economy:

2) It has wet cool summers and wet, mild winters, so for shelters and cloths, it affects economy by transportation, extra manufacture etc.
