What types of movements do we see among the lipids in the membrane?

Most membrane channels allow passage by simple diffusion of small inorganic ions of a specific type and may also be voltage gated. The solute binds to a protein carrier on one side of the membrane and is released on the other side after the transporter undergoes a change in shape, the movement of molecules across a cell membrane from a region of their lower concentration to a region of their higher concentration in the direction against some gradient or other obstructing factor.

Correct question is:

Frogs and toads belong to the order Anura. The smallest organism in this order is about 7 millimeters long, while the largest member is about 30

centimeters long. Which of these lists best describes this order?

a. Order Anura:  338 families, 28 genera, 4360 species

b. Order Anura:  28 families, 338 genera, 4360 species

c. Order Anura:  338 families, 4360 genera, 28 species

d. Order Anura:  28 families, 4360 genera, 338 species

b. Order Anura:  28 families, 338 genera, 4360 species

The families are biggest part followed by genera and then each genera has multiple species, this is described by nomenclature of biological species. Therefore option B is correct as the numbers are also increasing because families will be fewer than genera and genera will be fewer than species.
