Without external forces the third generation of the bacterium and the original Parent sale will have approximately blank matching DNA sequences a 100% fee 12.5% C 33% D 25%

Answer 1

To determine the approximate percentage of matching DNA sequences between the original parent cell and the third generation of bacteria, we need to consider how DNA is inherited through generations.

Assuming the bacteria undergo binary fission (as is typical for bacteria), each time the cell divides, it creates two cells with identical DNA. Hence, for each generation, the DNA remains significantly unchanged.

1. First Generation: The first generation will have 100% matching DNA sequences with the parent cell, as they are direct clones.
2. Second Generation: The second generation (which comes from the first generation) will also have 100% matching DNA sequences with the original parent.
3. Third Generation: The third generation still originates from the parent, and thus it will likewise have 100% matching DNA sequences with the parent.

Since the process of reproduction in bacteria (binary fission) maintains the same DNA (unless mutations occur), the DNA of the third generation of the bacterium will have 100% matching sequences with the original parent cell if we are considering just a basic binary fission without accounting for mutations or environmental factors.

Therefore, the answer would be approximately 100%. However, if we are considering some level of divergence or mutations over generations (which typically might be brought up but not stated here), additional context would be needed.

Given the available options, the most fitting answer would be:

• 100% (not listed among the options)
• Given the options, 12.5%, 33%, or 25% would imply certain evolutionary divergence, which typically wouldn't occur in simple binary fission without mutations.

If forced to choose among the given options strictly considering mutations or changes, one could consider a lower percentage, as in a hypothetical scenario that allows for mutation, but you mentioned the lack of external forces.

So, the most accurate answer without further context or provided methodologies is 100% matching, which does not make use of the provided answer choices.
