Interior (lower concentration
of glucose)
glucose is an important biomolecule. which of these statements is true regarding the movement of glucose into and out of
cells?
glucose, a small molecule, can diffuse between the phospholipids.
glucose requires both a membrane protein and atp energy in order to
enter or exit a cell
glucose, a nonpolar molecule, can pass freely across the phospholipid
bilayer from high to low concentration
glucose is a large, hydrophilic molecule and must use a channel protein to
enter or exit a cell, but does not require energy.

what? are the statements?

we solve the problem using the hardy-wineberg equation.

let us start with the homozygous recessive proportion of individuals with sickle cell anaemia,

we have the proportion as q² = 0.25.

∴ q = 0.5 (frequency of hbs in population)

further,

solving for the frequency of normal cell by using the fact that,

p + q = 1

∴ p = 1 - 0.5 = 1 - 0.5 = 0.5

now we can calculate 2pq in p² + 2pq + q², which is the frequency for heterozygous carriers of sickle cell anaemia,

∴ 2pq = 2 x 0.5 x 0.5 = 0.5

and the homozygous normal cell individuals proportion is given by the expression,

∴ p² = 0.5² = 0.25

hence, the carriers for sickle cell anaemia are in proportion, 0.5, or 50%.
