Answer:
The inner or cytoplasmic membrane, impermeable to polar molecules, regulates the passage of nutrients, metabolites, macromolecules, and information in and out of the cytoplasm and maintains the proton motive force required for energy storage.
Explanation:
Answer:
Solutions are formed when the water's polar molecules separate the polar molecules of an ionic or molecular compound
Explanation:
Water can hydrogen bond to other molecules due to the O-H bond present in water with partial charges. Water can form hydrogen bonding with other polar molecules. The answer would hence be Solutions are formed when the water's polar molecules separate the polar molecules of an ionic or molecular compound(because polar water dissolves polar molecules in between their interactions).
The nucleus of the cell directs cell activity and acts like the control center. This is the place where gene activity is controlled in terms of the replication of the genes. In addition the movement and actions of the cell are also dictated from the nucleus.
Muscle cells need a specific form of energy for contraction and cannot use the energy released directly from breaking down glucose or triglycerides. Rather, body cells must first convert food to adenosine triphosphate (ATP). <br /><br /> Food is digested and processed into ATP through sever different stages.
