Which statement is true? Membrane phospholipids always comprise the majority (by weight %) of a cell membrane. The fluid mosaic model considers biological membranes to be a sea of lipids floating in the aqueous fluid of the cytoplasm. All membranes in a given cell have the same lipid composition. Lipid bilayers are essentially impermeable to polar solutes.

lipid bilayer are essentially impermeable to polar solutes

Explanation:the cell membrane is a phospholipid bilayer.it is composed of lipids,proteins and carbonhydrates attached.the lipid bilayer forms the bulk of material on the membrane as a result it is impermeable to the movement of polar molecules in and out of the cell.small and non polar substances can pass through the bilayer of the membrane. the lipids and proteins occurs in varying composition in the membrane, depending on the

cell .the membrane has both a hydrophobic end and a hydrophilic end.the hydrophobic ends of the membrane folds toward each other.while the hydrophilic end is exposed to the water phase.the membrane is very flexible and thin and acts as a barrier that separates the cells external and internal environment

Lipid bilayers are essentially impermeable to polar solutes.

Explanation:

The lipid bilayer is a thin polar membrane made up of two layers of lipids,  proteins and carbonhydrates, these membranes are flat sheets that form a continuous barrier around cells and their structures. It is the barrier that keeps ions, proteins and other molecules where they are needed, preventing their dispersion. It is impermeable to the movement of polar molecules in and out of the cell, where small and non polar substances can pass through the bilayer of the membrane.

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.
