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:
Evaporation, transpiration, sublimation is the process by which the water moves from land to air. Evaporation is the phenomenon by which the water from the sea, ponds, river, oceans evaporate to go in air.
Explanation:
Bones are made up of Calcium Phosphate given by the chemical formula, . When bones are kept in Hydrochloric acid, given by the chemical formula, HCl, they become soft because the calcium compound present in the bones changes its form. The following double displacement reaction takes place when the bones are kept in HCl,
--->
Calcium chloride is water soluble, and gets washed away. This makes the bone thin and soft.
Answer:
clear example of homologous structures is the forelimb of mammals. When examined closely, the forelimbs of humans, whales, dogs, and bats all are very similar in structure. Each possesses the same number of bones, arranged in almost the same way. ... They are analogous structures.
