Extraction of aluminium metal takes place in three main stages¿mining of bauxite ore, refining the ore to recover alumina and smelting alumina to produce aluminium. Bauxite is mined by surface methods (open-cut mining) in which the topsoil and overburden are removed by bulldozers and scrapers.
Answer:

Answer:
The best answer to the question: These characteristics make primates particularly well adapted to what type of environment? Would be: the arboreal environment.
Explanation:
According to the video, primates, which subdivide into several groups, including the apes, from which also humans evolve, have, depending on their group, specific anatomical features and traits that allow them to survive in their environment. One such anatomical trait is the presence of larger brains than other mammals, long limbs, long fingers and strong lower limbs that allow them to adapt to tree life and survive in forest regions. Also, they tend to have a much more acute sense of vision due to their larger brain, but a much more limited sense of smell than other mammals. These characteristics become basic for them to live and survive in forest environments.
Answer:
A, B and C may be true
Explanation:
The three-dimensional structure (3D) of a protein, also known as tertiary structure, is critical to its function. In general, the 3D protein structure consists of alpha-helix and beta-sheets (secondary structures) associated through disordered coiled-coil regions. Genetic mutations may cause modifications in the 3D protein structure by modifying amino acids that are added to the growing polypeptide chain during the process of translation. In consequence, the relationships among amino acids (i.e., the intermolecular attractive forces that hold them together) may also be altered by these mutations. In general, mutations that generate amino acid changes at the active site of the enzyme will have a deleterious effect, thereby decreasing or inactivating protein function. However, there are situations where a mutation may be beneficial and can eventually increase the rate of reaction of a protein.
