Which of the following is a cost of mining aluminum from new bauxite deposits in tropical areas? a. preserving remaining aluminum reserves. b. transporting a relatively heavy metal. c. threatening rain forest organisms. d. producing toxic salt cake.

The correct answer is - C. Threatening rain forest organisms.

The mining of the aluminium from the new bauxite deposits in the tropical ares of the world unfortunately lead to the destruction of the rain forests and the organisms living in them.

In order for the mining to take place, the area needs to cleared from the rain forest. Also, roads need to be made in order for the ore to be transported, and to make roads, lot of rain forest needs to be cleared, again. The mines and the rods will be on a very large area, thus the destruction of the rain forest being on a large scale, and because the environment will be destroyed, lot of species of flora and fauna will become threatened. Also, the mining results in pollution, mostly in the rivers, thus affecting the organisms in the rivers as well.

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
