Correct option C) Hydrophilic portions of the lipids are in the interior of the membrane.
Lipids and proteins free to move laterally in membranes because both are inserted into a fluid lipid bi-layer and they are able to diffuse laterally through the membrane.
Lipid Composition of Cell Membranes is a important property of lipid bilayers which is behave as two-dimensional fluids where individual molecules are rotate and move freely in lateral directions
Membrane proteins and phospholipids both are unable to move back and forth between the inner and outer leaflets of the membrane at an appreciable rate. Phospholipids in the lipid bilayer can either move rotationally, laterally in one bilayer, or undergo transverse movement between bilayers.

Answer:
Glucose in the blood
Explanation:
When we eat and the level of glucose in the blood rises, it stimulates the release of insulin into the blood stream. It makes sense, because insulin is necessary for glucose to enter the cell across the membrane and be used as a source of energy.The problem arises when we eat too many carbohydrates for too long and the glucose level in the blood is constantly too high. After a number of years this causes insulin resistance. In other words, each time an ever greater concentration of insulin is needed to perform its function and eventually this leads to diabetes, when the pancreas just cannot produce any more insulin.

I think a change of land use can alter heat distribution patterns and surface water runoff. Surface runoff is water, from rain, snow melt, or other sources of water, that flows over the land surface, and is the major component of water cycle. The change of land use may alter surface water run off that occurs on surfaces before reaching a channel.
Answer:
compound
Explanation:
A leaf is said to be simple, when its lamina is entire or when incised, the incisions do not touch the midrib. When the incisions of the lamina reach up to the midrib breaking it into a number of leaflets, the leaf is called compound
