Attached is Model 1. I found the exercise on the internet.
A. The portion of the molecule that's polar is the head of the molecule - phosphorus containing group plus the glycerol backbone.
The other part of the molecule has two fatty acid chains which are hydrophobic meaning that they are nonpolar.
B. Yes, it would mix well with water because polar molecules are dissolved in water perfectly. Their partly positive portion and their negative polar connect to the positive charge of the H atoms and negative charge of the O atom of the water molecules.
Protocells are capable of Growth and Division.
C. hypothesis. He is giving a possible answer to the question "why did the celery crisp when placed in water?"
The statement "<span>A body buried will completely skeletalize faster than one left on the surface of the ground" is FALSE. It is said that a body placed above the surface of the ground could decompose for about eight months until it becomes skeletalize, compared to a body being buried below the ground.</span>
