Hi!
The structure of a plasma membrane will consist of both proteins as well as lipids. This membrane is considered a boundary which will separate the living cell away from their non-living surroundings.
Then the common characteristics of this membrane could be that it is made up of two layers of phospholipids and that it has a wide variety of proteins embedded in it.
Hope I helped!

Answer:
The production of peptides linking aminoacids through peptidic bonds
Explanation:
Chemically, peptides are synthesized by condensation where the carboxyl group of one amino acid is linked to the amino group of the other amino acid. The most common way to make a chemical peptide synthesis is linking first the carboxyl end of one amino acid to the amino group, not in the other direction. The opposite reaction, starting from the amino end and linking to the carboxyl end, is made in biosynthesis made by living organisms.
Answer:
Water molecules are polar, so they form hydrogen bonds. This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density.
Since the blood is moving out of the heart by the left ventricle and aorta the blood needs to get pumped and circulated through the heart. More it contracts the better circulation of blood throughout the body!
