It starts as a raindrop which is rain than it goes to the ocean,rivers,puddles or any body of water and from there it evaporates which makes the clouds and than it starts all over when the clouds already got enough water.
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.
Hundreds or thousands of years.
Answer:
coz the modern cells have a lot more complex structures which had evolved along time
This is true because eukaryotic cells are the organism cell. TRUE
