Explanation:
Water is generally regarded as universal solvent due to its ability to dissolve a wide range of compounds.
A water molecule has partial positive and negative charges on it thus, it is a polar compound.
- The binding rule for substances to dissolve one another is that they must be like one another.
- Polar solutes or substance only dissolves in polar solvents. Non-polar substances will dissolve in non-polar solvents.
- Water is polar and ionic substances are polar too.
- In water, the positive end of a salt is completely surrounded by water molecules and they hydrate it. The same analogy goes for the negative end.
- This is called hydration.
- The hydration complex keeps the salt dispersed in the water.
- This why water is able to dissolve a broad range of substances.

Answer:
the optimal pH for enzyme function is 6 but it can function well between a pH range of 2 to 7 which is the pH in small intestine. At highly alkaline pH the enzyme will denature.
Explanation:
Answer: It is permeable and water flows through it.
The unsaturated zone is also called as vedose zone. It is a zone that lies above the ground water table. It includes the subsurface layers of soil. The soil and rocks present in this region consists of pores, which allows the water from the surface of soil, being absorbed and seep underground due to the effect of gravity and hence, forms a groundwater reservoir or saturated zone.
Hence, this can be said that unsaturated zone is not filled by water because it is permeable and water flows through it.
Answer:
Ingestión, digestión, absorción, asimilación y egestión.
Explicación:
La ingestión, la digestión, la absorción, la asimilación y la egestión son los cinco procesos que intervienen en la nutrición y la alimentación. La ingestión es la absorción de los alimentos, la digestión es la descomposición de los alimentos de moléculas grandes a moléculas más pequeñas, la absorción es la toma de nutrientes de los alimentos por la célula, la asimilación es el proceso de absorción de vitaminas, minerales y otras sustancias químicas de los alimentos y La egestión es el proceso de eliminar los alimentos no digeridos como heces del cuerpo.
