Explanation:
Some ions or molecules tend to move in the cell along a concentration gradient. Such types of movement is known as passive transport. In passive transport, molecules move from a higher concentration to a lower concentration. Such kind of movement doesn't require energy.
Other kinds of molecules or ions move against the concentration gradient i.e from a lower concentration to a higher concentration. Energy is required for these process to occur.The energy used is in the form of ATP.
Answer:
Surface mining is suitable for large, low-grade ore deposits which occur below a thin layer of rock or sand. Underground mining is used for small, high-grade deposits covered with a thick soil or rock above the ore. Alluvial mining is suitable for deposits in sand and riverbeds.
Explanation:
Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes.
