Two molecules that can cross a lipid bilayer without help from membrane proteins are oxygen and carbon dioxide. The property that allows this to happen is that both oxygen and carbon dioxide molecules are nonpolar which means that they can pass easily through the hydrophobic part of the membrane. The lipid bilayer is present in all cell membranes. It consists of two layers of the fat cells which are arranged into two sheets. It functions as a barrier which marks the boundaries of the cell. The inner part of a lipid bilayer is nonpolar since it is composed of the hydrophobic end of the phospholopids.

Explanation:
Good Laboratory Practice (GLP) is extremely important.
1. Organization
With GLP we can guarantee an organized work environment, which is essencial in a laboratory.
2. Safety
GLP promotes laboratory safety for personell, avoiding unecessary risks and preventing accidents.
3. Quality control
GLP ensures that experiments made and products developed in a laboratory have the demanded quality.
4. Reliability of results
GLP promotes quality of results reporting, wich directly influences the reliability of results.
Answer:
92.2 m
Explanation:
Given that:=
The breadth = 304 mm
Height = 0.014 mm
Let Length = x mm
Volume = 
Thus,
Volume = 
Also, 1 mm³ = 0.001 cm³
So, volume = 0.004256 cm³
Given that density = 2.7 g/cm³
Mass = 1.06 kg = 1060 g
So,
So,
0.004256*x = 392.59
x = 92243.89 mm
Length of foil = 92243.89 mm = 92.2 m
