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:
cell
Explanation:
A cell is defined as the smallest, basic unit of life that is responsible for all of life's processes. Cells are the structural, functional, and biological units of all living beings. A cell can replicate itself independently. Hence, they are known as the building blocks of life.

Nucleotides in general has three components. First is the phosphate group that acts as a backbone for the final nucleic acid formed. Second is the pentose sugar which is a 5 carbon sugar; in DNA the sugar is deoxyribose and in RNA the sugar is ribose. Third is the nitrogenous base; it can either be adenine, guanine, cytosine, thymine (in DNA) or uracil (in RNA).
The answer is systematic circulation.
