Answer:
The ways through which the minerals form include the following order:
2. a warm solution flows through a crack in the rocks there
1. a solution forms from a liquid and dissolved substances
3. elements and compounds leave as the solution cools
4. elements and compounds crystallize
Explanation:
From the explanations above, it could be seen that a warm solution (most probably water)<em> flows through the cracks in the rocks leading to dissolution of substances to form liquid. When the liquid cools, the elements leaves and crystallize as compounds.</em>
Answer:
The cornea
Explanation:
The cornea is the only part of a human body that has no blood supply; it gets oxygen directly through the air.
Question: Why is the countercurrent system of flow important for fishes?
Explanation and answer: Fishes use a design called 'countercurrent oxygen exchange' to maximize the amount of oxygen that their blood can pick up. They achieve this by maximizing the amount of time their blood is exposed to water that has a higher oxygen level, even as the blood takes on more oxygen.
