Disruptive selection is made of natural selection which favor both extreme phenotype and both from one extreme in directional selection. Stabilizing selection is favors the middle phenotype, average trait value over two extreme trait values.
Both the selection are disruptive selection favors phenotype while stabilizing selection favors average phenotype in population , eliminating both extreme.Disruptive selection also known as diversifying selection.
Stabilizing selection is natural selection pursue population towards the average or median . Normally environment favors average phenotype within a population.Both are two natural selection , affect the distribution of phenotype within a population,Applies to a phenotype trait.

Answer:The contrast of the difference between what is called "microevolution", and "macroevolution".
Microevolution concerns the transformation of traits in a population of a given species.
Macroevolution concerns evolution above the species level: it includes the diversification of high level taxa, (mass) extinctions, origin and diversification of clades, etc.
Speciation – the arising of new species, and the main processes likely to produce it stands at the boundary between those evolutions.
Notably, when people of the term "evolution" they typically think of macroevolution (think of Darwin's focus on species their origins and transformation).
Darwin's focused on species their origins and transformation.
Darwin on evolution proposed natural selection as the mechanism of evolution
- Note these important points he outlined:
• Individuals do not evolve: populations evolve
• Natural selection can amplify or diminish only heritable traits; acquired characteristics cannot be passed on to offspring
• Evolution is not goal directed and does not lead to perfection; favorable traits vary as environments change.
Explanation:
If after pouring iodine on an uninoculated plate clearings as well as in the transferred plates it means that
1. THE EXPERIMENT WAS NOT CONDUCTED PROPERLY.
2. THE UNINOCULATED PLATE WAS CONTAMINATED AND SHOULD BE DISCARDED.
3. THE CULTURE MEDIUM WAS NOT PREPARED PROPERLY BECAUSE THE STARCH WAS NOT MIXED WELL.
4. THE EXPERIMENT SHOULD BE DONE AGAIN WITH PRECISION AND CARE.
Genetic variation or coral spawning
The otoliths are small calcium carbonate crystals which put pressure on the cilia, inclining them, thereby stimulating the sensory hair cells.
They can cause problems for your health such as dizziness and vertigo
