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.
1) Since plants are a renewable resource and oil is not, we will eventually run out of the materials needed to make traditional plastic, but we will not run out of what we need to make plant-based plastic.
2) Farming has a much lower carbon footprint than oil extraction and processing does.
3) Plant-based plastic can be biodegradable.
Answer:
flagella and cilia
Explanation:
Flagella (singular = flagellum) are long, hair-like structures that extend from the plasma membrane and are used to move an entire cell, (for example, sperm, Euglena).
