Stratigraphic correlation is a process of matching up strata from various sites through the analysis of physical, chemical and other properties. It is also a study that involves establishing geochronological relationships between areas concerned with geological investigation of many succession. It is carried out by studying the different patterns and location of rocks on the earth so as to understand their relationships and age of the layer.
The daughter cells come together to make another identical parent cell.
First Part of the Cell Theory:
All living things are composed of cells.
Second Part of the Cell Theory:
Cells are the basic unit of structure and function in living things.
Third Part of the Cell Theory:
All cells are produced from other cells.
Given what we know, we can confirm that the scenario that best demonstrates the mechanism of apoptosis is 1, "An immune cell Self-destructs once it is no longer needed by the immune system".
<h3>What is apoptosis?</h3>
- This is what we describe as a programmed cellular death.
- This means that when a cell is no longer needed or is damaged or old, it is programmed to automatically self-destruct in order to make room for new cells.
- This is also an effective way to reuse the resources the cell contained.
- When this mechanism fails, it can often lead to the formation of cancer.
Therefore, we can confirm that option 1 which states "An immune cell Self-destructs once it is no longer needed by the immune system" is the best description available of apoptosis given its definition as a programmed cellular death.

Crab in Rocky shore By rock pools - deep in ocean as they get older
Typical day - just shuffle along the rocks
To get food - from rock pools use claws to get fish
As they get bigger, they eat protozoa, diatoms and smaller crabs that live on the ocean floor. When the crabs reach 2 to 4 years of age, they move to deeper water where they join the adult crabs that eat worms, clams, mussels, snails and sea urchins. They also eat sand dollars, barnacles, fish parts and algae.
Hard shell is their protection and claws as a defends mechanism
PredAtors - possibly birds while on shore but bigger fish on ocean floor
