Answer:
Extended Structure: Sodium chloride or diamonds.
The Same: Protons
Repeating: Atoms or series of atoms
It consists of three adjacent structural genes, a promoter, a terminator, and an operator. The lacoperon<span> is regulated by several factors including the availability of glucose and lactose. It can be activated by allolactose. Lactose binds to the repressor protein and prevents it from repressing gene transcription.</span>
Explanation:
The substance A and B will mix into one solution as it is a solvent interactions which is greater than or equal to the solute- solute and the solvent-solvent interactions. Thus when such interactions occurs, it is greater or equal to the some of the other two possible interactions. And here both have the same kind of interaction, and same magnitude, so they will makes to form a solution and mixes properly and spontaneously.
Answer: D. Circulatory System
Explanation: The circulatory system transports gases (oxygen, carbon dioxide), nutrients, and wastes found in the blood throughout the body.
