PH is a measure of how acidic<span>/basic water is. The range goes from 0 - 14, with 7 being </span>neutral<span>. pHs of less than 7 indicate </span>acidity<span>, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl </span>ions<span> in the water.</span>
At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.
Answer:
Answer:
Multicellular organism is the example of complexity of the natural world.
Explanation:
Multicellular organism such as human which is made of billions of cell. Each cell perform a specific function. The function of one organ is different from the other organ. For example, brain of human is made of millions of neurons which takes instructions from brain to the organs and bring messages from organs to the nervous system in the form of electrical impulses. In short every system in our body is full of complexity.
In order for multicellular organisms to maintain homeostasis B. their organ systems must work together. So the answer is letter B. This is because in order for the body to maintain hemostasis, it has to maintain the body temperaturw in any weather and climate it will experience.
Seeing that our species is constantly evolving, maybe it is starting to get more uncomfortable to walk on all fours.
