the answer is false at lest that is what i know
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.

Answer:
c. abc₃
Step-by-step explanation:
1. a atoms
There are eight corners, each containing an a atom.
No. of a atoms = 8 × ⅛
No. of a atoms = 1
=====
2. b atoms
There is one central b atom.
=====
3. c atoms
There are six faces, each containing a c atom.
No. of a atoms = 6 × ½
No. of c atoms = 3
=====
4. Formula
The simplest formula is abc₃.

Answer:
Neutrons play no role in the net charge of an atom, so you can ignore them here.
Proton = 7
Electron = 10
Net Charge = 7 - 10
= -3
Again,
Proton = 3
Electron = 2
Net Charge = 3 - 2
= 1
