The correct answer is going to be <span>C. It is the continuous movement of water under, on or above the Earth's surface</span>
After the digestion of carbohydrates, fats, and proteins in duodenum, the digested nutrients are absorbed in the ileum.
Ileum is a section of the small intestine, after duodenum.
Food is absorbed by diffusion and active transport. Villi on the walls of the ileum helps this process, since it can increase its surface area and provide a good blood supply, thus increase the rate of absorption.
Note that water can also be absorbed in the large intestine, those water absorbed there are the ones that cannot be absorbed in the ileum.
However, not all water is absorbed as we can notice that faeces are wet.
They are semi-permeable because they can diffuse and pass through the plasma membrane easily.
Earthquakes happen due to tectonic plate motion
The right answer is True.
Sustainable agriculture is the application to agriculture of the principles of sustainable or sustainable development as recognized by the international community in Rio de Janeiro in June 1992. It is a system of agricultural production that aims to ensure sustainable production of food, wood and fiber respecting the ecological, economic and social limits that ensure the maintenance over time of this production.
Sustainable agriculture aims to reduce the environmental impact of the sector. It is in particular an agriculture that better protects the biodiversity, the water and the soils that are necessary for it and which uses it better through the auxiliaries of agriculture and the ecosystem services. And also by creating more per capita wealth per unit of production, on a more equitable basis. These principles are based on the recognition that natural resources are not infinite and that they must be used wisely to ensure long-term economic profitability, social well-being, and respect for the environment (all three are pillars of sustainable development).
