Answer:
1. The one nearest the surface is the "zone of aeration", where gaps between soil are filled with both air and water. Below this layer is the "zone of saturation", where the gaps are filled with water.
2. Larger pores mean less friction between flowing water and the sides of the pores. Smaller pores mean more friction between flowing water and pore walls and more twists and turns for the water to navigate. A permeable material has a greater number of larger, well-connected pore spaces. An impermeable material has fewer, smaller pores that are poorly connected.
3. A cave is any cavity in the ground that is large enough that some portion of it will not receive direct sunlight.
A cavern is a specific type of cave, naturally formed in soluble rock with the ability to grow speleothems.
4. The size of the pores underground rock material has and if the pores are connected
5. Karst regions are formed when there is a chemical reaction between the groundwater and the bedrock. As rain, streams, and rivers flow over the earth's surface, the water mixes with the carbon dioxide that naturally exists in air, and the soil becomes acidic and corrodes the calcium carbonate rock. The carbonate solution seeps into fissures, fractures, crevices, and other depressions in the rock. Sinkholes develop and the fissures and crevices widen and lengthen. As the openings get larger, the amount of water that can enter increases.

Answer:
a) properties of the molecule as a result of abnormal interactions between adjacent hemoglobin molecules
Explanation:
In sickle cell disease, for example, a nonpolar amino acid (valine) replaces a polar amino acid (glutamate). This substitution of amino acids reduces the hemoglobin’s water solubility. The mutated hemoglobin molecules form long, stiff and rod-like crystals inside red blood cells which are otherwise not formed by normal hemoglobin molecules.
These abnormal crystals of hemoglobin cause the deformation of RBCs making them sickle-shaped that cannot properly squeeze through narrow blood vessels. Therefore, the substitution of single amino acid results in abnormal interaction of two or more hemoglobin molecules that are not exhibited by normal hemoglobin molecules.
