Answer:
B. Layers that cut across the most other features are youngest.
Explanation:
Using the principles of cross-cutting relationships, you can determine the relative age of rocks found in the ground. The idea behind it is that the geologic feature which cuts another is the younger of the two features, and it had been around for 400 years. It's not very precise but it is good for determining relative age.
The answer would be algae or phytoplankton
Answer:
The temperature was in the high teens but as the sun began its ascent it felt far warmer.
Every child feels displaced to some degree when a new sibling arrives.
Explanation:
Answer:
Quorum sensing.
Explanation:
Quorum sensing may be defined as the phenomena by which the bacteria can detect the specific stimuli and respond towards the cell population density. This process helps in coordinating gene expression.
Quorum sensing is used in prokaryotes for the cell to cell signalling and cell communication as well. The main evolution of quorum sensing in bacteria was to relay the information and helps in cell signalling by releasing the specific toxins. From the evolutionary point, the organism that are capable of quorum sensing would survive more in their environment, adapt well in their environment.
Thus, the answer is quorum sensing.
