it depends on what you are referring to. the lipid bilayer is exactly what it says.it is two layers compsed of lipids. lipid molecules have two properties: a hydophobi tail and a hydrophilic head. so when the bi layer is put together, it has the tails facing eachter and the heads out to react with water conditions in the body. the membrane is also embedded with proteins of all dffierent kinds that allows ions to cross and this allows for cell communication

True
Firstly, they are lipids. They have a non-polar / hydrophobic tail and a polar / charged / acid / hydrophyllic head. The charged acid head is enhanced in its capabilities by the addition of a phosphate [PO4--] group. Reported to be crucial to brain functions and available in nutmeat, this makes peanuts equal to 'brain-food'.
True.
True
True. Carbon dioxide is a nonpolar molecule because its linear molecular geometry and symmetrical distribution of polar covalent bonds result in a net dipole moment of zero. This means there is no separation of charge within the molecule.
False. Molecules can arrange themselves in the same way under specific conditions, resulting in the formation of structures with repeating patterns (e.g. crystals).
It is false. They are called "Macromolecules."
It is false that the loss of electrons from food molecules is reduction. Electrons are negatively charged subatomic particles.
