Answer:
(B) Lava has separated the population into two areas: an upland forest and a lowland marsh.
Explanation:
In allopatric speciation, individuals of an ancestral species may undergo evolution into two or more progeny species which arises when physical separation causes a geographic boundary, this barrier can be in the form of a mountain range, rockslide, river or lava.
As in this scenario, a lava flow divides the populations of annual herbaceous plants by altering the landscape. This will cause genetic divergence with varying heritable features among its many generations favouring different traits in the separate environment along with genetic drift. The Lava will separates the population into two areas: an upland forest and a lowland marsh.
Natural Selection: Naturally, living organisms produce offspring that will inherit characteristics that give that offspring higher and most successful chances of survival. So offspring are naturally born with traits that suits them best for survival. Natural Selection process also consist of in comparison of living organisms, those who adapt best to their environment and have flexible characteristics survive longer than those who don't.
The fly would no longer exist and all popuations will cease in their value
The answer is B) metaphase
Answer:
This is the spring tide: the highest (and lowest) tide. Spring tides are not named for the season. This is spring in the sense of jump, burst forth, rise. So spring tides bring the most extreme high and low tides every month, and they always happen – every month – around full and new moon.
