<h2>Nuclear Envelope</h2>
Explanation:
- <em>The endomembrane system</em> includes the nuclear envelope, the <em>endoplasmic reticulum, Golgi mechanical assembly, lysosomes, vesicles, just as the plasma layer</em>
- These cell parts cooperate to <em>alter, bundle, tag, and transport layer lipids and proteins </em>
- The nuclear envelope is a double membrane, implying that there are <em>two lipid bilayers</em>
- The nuclear lamina, a netlike cluster of <em>protein filaments, associates the layers of the nuclear envelope</em>
 
        
        
        
Answer:
The answer to your question is below
Explanation:
Glucose            it is a sugar and then a biomolecule. It is necessary in the 
                           cellular respiration because it helps in the production of 
                           ATP.
Small                 90% of the absorption of the nutrients is in the Small 
                            intestine.
H₂O                    water is a very useful molecule that is necessary in most of 
                            the chemical reactions.
Small                   I was doubting between small and large intestine, I finally
                            decided by small intestine because it absorbs 90% of all
                           the water.

Answer:
carbohydrates, lipids, proteins, and nucleic acids
Explanation:
There are thousands of different types of molecules in a cell, but there are only four major classes of biomolecules.
 
        
             
        
        
        
Answer:
These are needed to mimic the blood vessels which these organs will use for the supply or drainage of fluids e.g blood.
In addition the empty tunnels serve as the routes for nutrients and oxygen supply  for the organ.
In summary the tunnels provided  a vascular structure to support the organ
