Answer: A) Layers 1 and 2.
Explanation:
Secondary succession refers to when species of plants and animals come back to recolonise an area that was destroyed by a natural disaster of some sort or human activity that change the makeup of the area but somehow left it still capable of supporting life.
As the species that come during secondary succession come after the land has been destroyed so to speak, they would be the later species to arrive which would mean that when they died they would be the closest to the surface when their body decays.
Secondary succession would therefore most likely be observed between layers 1 and 2.
Answer:
A solution at pH 6 contains<u><em> 100 times more H+</em></u> than the same amount of solution at pH 8.
Explanation:
pH of a substance determines the hydrogen ion concentration of a solution. Acidic solution tend to have a higher concentration of H+ ions as compared to that of water. They have a concentration greater than 1 × 10^{-7} M. Basic solutions have lesser concentration of H+ ions as compared to that of water. They have a concentration lesser than 1 × 10^{-7} M. A solution from pH range 1 to 6 will be acidic. A solution from pH rage 8-10 will be basic.
