The mantle is the largest layer
99% of the water is used for the "Transpiration" by the plants.
The right answer is a. they contain many small, repeating subunits bonded together.
In chemistry and biology, a polymer is a molecule made up of a chain of similar molecules, called monomers; a polymer is a macromolecule resulting from the assembly of many identical units (monomers), a chemical compound with repetitive structural units.
DNA, glycogen and proteins are polymers
Surface mining, which is also known as strip mining, is when soil and rock overlaying mineral deposit is removed. It can cause habitat destruction, air pollution from dust particles, soil erosion and pollution. Subsurface mining is removing deposits from the Earth by drilling underneath layers of rock and dirt. To keep the pathways clear, <span>mining companies have to pump out large amounts of water, which go into surface ecosystems. That disrupts the ecosystem by changing the pH conditions of soil and water sources. Placer mining is mining of stream bed deposits for minerals, a way of obtaining minerals and metal resources. Although, because it is small, causes less damage to the surrounding environment it still can disrupt river ecosystems with pollution and sediments.
I hope this helps!!
