Answer:
Older rock layers are found under younger rock layers
Explanation:
It directly states in the sentence above the diagram that the bottom layer of rock is the oldest.
Solution:
1. (37 + 12t) - 37 = (85) - 37
2. 12t/12 = 48/12
3. <u>t = 4</u>
Answer:
True
Explanation:
According the Mendelian research, it is always good to work with large sample size because small sample size are prone to deviations. Small sample sizes easily get affected by genetic forces such as genetic drift, selection, immigration etc.
Hence the given statement is true
Answer:
C Differences among temperature, air pressure, and density
Explanation:
Classification of the atmosphere layer will be different based on the temperature, air pressure, and density. Generally, air pressure and density will go less at the higher layer, but the temperature varies greatly. Altitude and latitude define a location on earth, not the layer of atmosphere. Most weather just happens at the troposphere layer. The distance from ground level can be used as a rough estimate but not as precise criteria.
