Answer:    A. Glucose
Explanation:  Monosaccharides, or simply sugar, is the simplest type of sugar, which cannot be further processed, i.e. hydrolysed to produce even simpler sugar. Monosaccharides are basic units of carbohydrates, have a solid crystalline structure and are easily soluble in water. Some of the monosaccharides are glucose, fructose, galactose. They are also the building blocks of some of the more complex structures of disaccharides and polysaccharides, such as lactose, sucrose. cellulose.
 
        
             
        
        
        
The nervous system helps:
Receptors in muscles provide the brain with information about body position and movement.
The brain controls the contraction of skeletal muscle.
The nervous system regulates the speed at which food moves through the digestive tract.
The nervous system regulates respiratory rate
The nervous system regulates heart rate and blood pressure.

Answer:
In eukaryotes, thousands of chemical reactions are able to take place in  separate compartments called organelles.
Explanation:
Organelles are specific cellular structures that are the means of compartmentalizing the various functions that occur within cells.
Examples of organelles and their functions are:
- <u>Nucleus</u>: contains DNA and in it occur the replication of this molecule and its transcription into RNA.
- <u>Rough endoplasmic reticulum</u>: protein synthesis and conjugation of these molecules occurs.
- <u>Mitochondrion</u>: houses all oxidative phosphorylation reactions and the electron transport chain for ATP synthesis to occur.
The organelles are then the structures that allow the development of the multiple functions that a cell has.
The other options are not correct because:
- <em><u>Bacteria</u></em><em> is a prokaryotic organism.
</em>
- <em><u>Prokaryote</u></em><em> refers to simple organisms that lack organelles.
</em>
- <em><u>Proteins</u></em><em> are biomolecules that allow the structure and function of living beings.</em>
