It’s A, and the relationship between cellular representation and photosynthesis creates a balance
Answer:
The correct answer is conservative model.
Explanation:
There are 3 hypothesized DNA replication models: semi-conservative, conservative and dispersive model (see figure). Heavy isotope of nitrogen makes diference when density gradient centrifugation experiment conducted and two diffent bands contaning different isotopes of nitrogen are observed. With one band only containing 14N means bacteria only copies one strand in one replication which supports semi conservative model.
The answer is B) hunting in pacs. Everything else is ‘what you’re born with.’
Answer: The correct answer is-
Allopatric- option 2.
Sympatric - option 1.
Allopatric and sympatric are primarily the two major mechanisms for speciation ( formation of new species from an ancestral species).
In allopatric speciation, a population splits into two different species when it is isolated by physical or geographical barrier.
On the other hand, sympatric speciation occurs wihtin the same area. A population splits into two species that is becomes reproductively isolated when a change in the chromosome number occurs.
Thus, option first corresponds to sympatric whereas option second shows allopatric speciaton.
