The answer in here is Na+. We know this because <span>a cell membrane is non-polar which means that polar molecules or charged particles (ions) will not be able to go through without a channel. Likewise, small non-polar molecules will be able to diffuse without a channel - straight through the membrane. That is why the best option is Na+</span>

A hypothetical flowering plant produces blue, light blue, and white flowers. To determine the inheritance pattern, the following
olasank [31]

Answer:

d. incomplete dominance

Explanation:

When none of the alleles of a particular locus completely masks the expression of the other allele of the same gene, it is called incomplete dominance. If the allele B gives "blue" phenotype and allele b gives white phenotype, a cross between blue (BB) and white (bb) parents would produce all the progeny with genotype Bb. Since the allele B does not completely prevent the expression of allele b in the heterozygous condition, the phenotype of the F1 hybrids would be "light blue". Therefore, it is an example of incomplete dominance.

blue (BB) x blue (BB) = all blue (BB)

white (bb) x white (bb)= all white (bb)

blue (BB) x white (bb)= all light blue (Bb)
