limestone, carbonate rock, salt beds, or rocks that can naturally be dissolved by groundwater circulating through them.
Explanation:
Answer:
pressure gradient
Explanation:
The correct answer would be pressure gradient.
<em>A pressure gradient is created when there is a difference in the amount of pressure between two points or locations that are adjacent to one another.</em>
In this case, the two locations that are adjacent to one another are the inside and outside of the lung. When one breathes in, the pressure inside the lung is more than that of the outside and the lung expands as a result. When we breathe out, the pressure outside is more than that of the inside and the lung collapses.
Answer:
it's a molecule
Explanation:
if it was just hydrogen it would be an atom, but when you add another element it becomes a molecule.
Answer:
Coevolution
Explanation:
Coevolution is a process in which two species evolve together because they exert selective pressures mutually. This means that one of the species changes genetically in response to a genetic change in another species. Thus, both species reciprocally affect each other's evolution. These genetic changes, which go hand in hand, are reflected in the phenotypes, that is, in the morphological traits of the species.
The coevolution of plants (i.e the orchid) and pollinators (i.e the moth) is a typical example of coevolution. The flowering plant adapt to a pollinator, which in turn adapts to the plant. In this case, the nectar tube and the tongue of the moth coevolved together and the two species benefit from that. The orchid guarantees the dispersion of its pollen while the moth guarantees its food.
