Describe the main components of a biological membrane by filling in the missing terms.

The main components of a biological membrane are lipids, proteins and sugar.
Most of the biological membranes have two layers of lipids forming two sheets where proteins are in between the lipids trespassing both layers of only one, either to one side of the membrane or to the other. There are also sugars attached either to the lipids (called glycolipids) or to the proteins.

True statement gravity force is more on bigger mass, less on smaller mass.all mass fall on planet with same acceleration and speeds

That would be a working theory.
