Draw the structure of a biological membrane with simplified structures of phospholipid (saturated and unsaturated), integral and peripheral proteins, sterols and oligosaccharides. Label the structures and write their functions in parenthesis

Explanation:

Phospholipid: Phospholipid tails can be saturated or unsaturated, those which have double bonds are unsaturated phospholipds, which have only single bonds are called saturated fatty acids. They are found in both inner (PS) and outer membrane(PC).

Proteins: i)  Intergral protein: which are integral part of plasma membrane,

ii) Peripheral proteins: which are found on the periphery of both outer and inner membrane.

Sterols; are found in both ,inner and outer membrane.

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
