Answer:
When the seed germinates, the two cotyledons emerge from the soil to form the seed leaves. The seed leaves nourish the plant until it can form its true leaves. (Not all dicots' seed leaves emerge during germination; for example, peas are dicots, but the pea cotyledons remain underground.)
Explanation:
Answer:
The emergence of new species from surviving ancestral species and both species continue to interact during a transition period is known as Sympatric Speciation.
Explanation:
Hybrid Zone is the area where two species continue to interact. Hybrid offspring are produced by two different species.
1) hybrid offspring
2) zones
3) reinforces
4) zones
5) Slow down
6) gradual speciation model
7) punctuated equilibrium
Prokaryotic have no organelle but the eukaryotic do have cells
The chemical reaction could be vary with the condition but the nuclear decay rate is constant, here the option A is the right option.
