Answer:

See the answer and explanation below, please.

Explanation:

- Proteins: integral, peripheral and membrane fixed to lipids.

- Glucids: covalently bound to proteins or lipids; they can be poly or oligosaccharides. They form the glycocalix on the outside of the membrane and its function is to support the membrane and cell recognition.

1. Why are two thick cotton sheets warmer than one single blanket
mash [69]
Since the air is a great thermal isolator, the windows prevent heat exchange better than one made out of a single thick sheet of glass. The air between the thin blankets is not moving around and will form an isolating layer that acts exactly like another blanket, thus improving the thermal isolation
