Before
Principle of superposition of strata
Younger
Principle of cross cutting
Explanation:
Relative dating is method of assigning ages to geologic events in nature. This is based on certain principles and laws proposed by earlier geologists.
Relative dating differs from absolute dating in that absolute dating assigns real quantitative numbers to geologic events.
- From the analogy of the building provided, according to the principle of superposition of strata, the oldest layer is at the bottom of the sequence and the youngest on top.
- The lowest part of the section must of the section must have been constructed before the parts above it were constructed.
- Based on the principle of cross cutting "geologic features that cuts another are usually younger than the sequence they cut through ".
- The cracks on the wall is cross-cutting feature that appeared after the wall was formed.
- Therefore, it is younger than the wall.

Hey
Correct answer: Scavenger
Why? Because a scavenger is an animal that eats dead animals. A vulture is a example of one
have a good day
Yes, because the envelope can be a important document- so therefore it can be considered "confidential".
Answer:
1. Bacteria cannot live above 100 degrees Celsius; archaea can thrive in extreme temperatures. Archaea are actually extremophiles. They can survive in extreme physical and geochemical conditions.
2. Bacterial cell walls have peptidoglycan (mesh-like structure also known as murein); archaeal cell walls do not have peptidoglycan.
Answer:
Parasitism
Explanation:
This type of relationship involves one organism living with, on, or inside another organism and harming it. This relationship involves:
Host - the one being harmed in parasitism in this case the fish.
Parasite - the organism (the one doing the harm) that benefits in parasitsm in this case the leech.
