The answer is a C. The offsprings from this generation are from a cross between parents who are heterozygous (one parent) and homozygous recessive. This means that all the offsprings of the filial 1 (one) generation will carry a recessive allele. However, those with an equivalent dominant allele will not exhibit the attached earlobe trait. This is shown by the Punnet square below;

Which would least likely be able to cross the phospholipid bilayer of the cell membrane answers?
ruslelena [56]

Answer;

-Large polar molecule are list likely to cross the phospholipid bilayer.

Explanation;

-A large polar molecule would be the least likely to passively diffuse through a plasma membrane without the help of a transport protein. Both its size and the hydrophobic interior of the membrane would restrict it.

-Only small uncharged molecules can diffuse freely through phospholipid bilayers. Small nonpolar molecules, such as O2 and CO2, are soluble in the lipid bilayer and therefore can readily cross cell membranes.

-Ions and large polar molecules cannot pass through the lipid bilayer. But more specifically, whether a molecule can pass through the membrane depends on its size and its electrical nature.

Explain how an unbalanced translocation occurs and how it affects humans
Serga [27]
Translocations may be balanced when there is an even exchange of material with no genetic information extra or missing, and ideally full functionality. Or can be unbalanced where the exchange of chromosome material is unequal resulting in extra or missing genes. For example a child who has an unbalanced translocation may have learning disabilities, developmental delay and health problems. The seriousness of the disability depends on exactly which parts of which chromosomes are involved and how much missing or extra chromosome material present.
