Which of the following statements about the movement of lipids in the bilayer is true? a) Lipids are free to flip from one plane
to the other of a bilayer b) All of the above c) Lipids are free to rotate within one plane of a bilayer d) Lipids are free to move within one plane of a bilayer e) Only A and B.
Nowadays it is known that the lipid bilayer of the cells is not static, actually, the modern Fluid-Mosaic membrane model establishes that the lipids move constantly within the lipid bilayer. The lipids are able to rotate within its axis, the lipids are able to movement laterally moving from one site to the other within the same plane, and also can move from a plane to the other plane in what is known as transverse "flip flop" movement.
Each avocado fruit contains one large seed. Each tangerine fruit contains a dozen seeds or more. Because the tan- gerine tree produces more seeds per fruit, it has a higher biotic potential than the avocado tree.
