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.
There are actually 2 kinds of minerals mainly in our human bone. They're calcium and phosphorus.
There are also other types of minerals, but they're in very small amounts. Mainly are those 2.
We can take in these 2 minerals by eating food such as diary foods, meat, eggs etc.
