Answer:
I believe the answer is all amoeba come from other amoeba
C2H2O4 C2HO4- + H+
0.175 - x x x + y
C2HO4- c2o42– + H+
x - y y x + y
K2 = (y) (x +y) / (x-y)
As, y << x
So, K2 = (y) (x) / (x)
K2 = y =6.1 × 10^–5
Hence, concentration of (c2o42–) 6.1 × 10^–5 M
Explanation:
The idea behind using fossils to correlate two land masses was first put into limelight by a British geologist, Williams Smith.
According to the principle of fossil and fauna succession "fossils and fauna succeed one another in a define order".
This implies organisms evolve in predictable manner.
Since we know that certain types of organisms live within a period in time on the earth surface, we expect that such organisms would be fossilized in the geologic record and preserved.
- Identify the fossil record in one part of the land mass. Log the rock types with the corresponding fossils in them.
- On the other side, repeat the same process.
- Look for unconformity surfaces where some part of the stratigraphic records might have been lost.
- If the fossil records on one side corresponds with that on the other other side, it suggests that the land masses must have once been joined together.
- The logic is that when the organism were on the same land mass, they thrived and lived together.
- They became fossilized together till the lands separated.

Barrier island refers to the large sandbars along the coastline that form
from deposition of sand over long period of time.
<h3>Features of a Sandy environment </h3>
The features of a sandy environment include the following:
Barrier Island are formed when sand is deposited over a long time and this
helps to prevent erosion along the coastline area.
