Answer:
E. This population is in Hardy-Weinberg equilibrium.
Explanation:
A population in Hardy-Weinberg equilibrium maintains constant allele and genotype frequencies over generations. To obtain the Hardy-Weinberg equilibrium, none of the evolutionary forces (genetic drift, mutation, natural selection, etc.) should be operative on the gene pool as they deviate the population from the equilibrium.
According to the given information, the allele frequencies and hence the genotype frequencies in a population of butterflies are constant over two decades. This shows that the population is at Hardy-Weinberg equilibrium and is not evolving.
Answer:
The atmospheric pressure goes on decreasing as we go up above the sea-level. Therefore, the amount of oxygen also decreases at higher altitude. Due to this reason, mountaineers carry oxygen cylinders with them, while climbing high mountains

Answer:
The label A corresponds to Convergent boundary zones
Explanation:
When two oceanic plates collide, it occurs oceanic convergence. The thicker and older plate subduces under the other plate, and at this point, it starts the volcanic activity. As the thicker plate descends, it is heated and melted and its materials are incorporated into the mantle. The fast subduction originates magma that ascends to the surface by crevices. This makes place to the formation of grouped <u>volcanic islands</u>, t<u>he island arches</u>. Subduction zones coincide with deep-sea <u>trenches</u> or depressions in the ocean bed. The volcanic islands are arranged in a circumference arch shape, which is bordered by a fossa. Most of these are located in the western Pacific, where the pacific crust is older and thicker, and hence it submerges easier in the mantle.
