Answer:
A series of nonpolar amino acids would most likely be located in the interior region of the tridimensional molecule.
Explanation:
Proteins are formed by linearly arranged amino acids, each with a side chain: the R-group.
Of the 20 different amino acids that compose the proteins, about half of them -10- are non-polar. Their R-groups are not stable if they are in contact with water, meaning that non-polar amino acids are hydrophobic.
When proteins are synthesized, they acquire a three-dimensional structure that makes them more stable. Lineal polypeptides get folded and turn into a shape that makes them more stable in the environment and capable of accomplishing their biological role. When they are in an aqueous media, their bent shape leaves the hydrophilic R-groups in contact with water. The hydrophilic R-groups stick in the center of the polypeptide, facing the protein interior, and avoiding interaction with water.
Answer:
These spheres are closely connected. For example, many birds (biosphere) fly through the air (atmosphere), while water (hydrosphere) often flows through the soil (lithosphere). In fact, the spheres are so closely connected that a change in one sphere often results in a change in one or more of the other spheres.

The correct answer is option A, that is, blood.
Cell theory in biology refers to the universally acknowledged scientific theory that living species are constructed of cells, that is, they are the basic fundamental and structural unit of all species, and that all the cells arises from the pre-existing cells. The theory is credited to Schwann and Schleiden. The three postulates of the theory are:
1. All living species comprises of one or more cells.
2. Cell originate from the pre-existing cells.
3. The cells is the fundamental unit of organization and composition in organisms.
