Answer:
Diffusion, osmosis and active transport are three similar chemical methods by which single molecules or very small structures are moved across membranes or relatively short distances, often within or between cells.
Explanation:
The movement of substances in and out of cells is a very important part of biology as without it no cell and so no organism could live very long. Substances can only cross the protective cell membrane by diffusion, osmosis or active transport. Mass flow only works at the organ, tissue and whole organism level.

Genetic screening uses a variety of laboratory procedures to find out if a person has a genetic condition or disorder or is likely to develop a disease based on his or her genetic makeup. Individuals may wish to be tested if the family shows a history of one specific disease such as Huntington's Disease or breast cancer, if they show symptoms of a genetic disorder which could be improved by early diagnosis, or if they are planning a family and are concerned about the possibility of passing on a genetic trait to their offspring. This last type of screening can look at the parent's genotype or look at the genotype of the fetus or newborn. This type of screening can also look for a specific disorder or can be done as a general test for common disorders as in prenatal testing or more commonly newborn screening.
