When someone is lactose intolerant, it means its intestine cannot absorb lactose, which will stay in the lumen and be consumed by intestinal bacteria and produced gases, that's why intolerant lactose people have flatulence and abdominal pain while eating food with lactose in it.
Let's go back to the question, before being consumed, lactose in the lumen intestine will attract water from the enterocytes to its side by oncotic pressure.
Do not confound oncotic pressure (which concerns macromolecules like sugar or proteins) and osmotic pressure (which concern micromolecules like small ions (sodium potassium and chloride...)).
Answer: Gene flow is the movement of alleles from one population to another as a result of the migration of individuals. This causes a reduction in the differences between populations. ... Genetic drift is a change in allele frequencies due to change of events in a small breeding population.

Hope this helps :P
plz give me the brainliest if it does : )
Type 2 diabetes has 2 causes: genetics (mutation in a gene or genes) and/or lifestyle poor choices (overweight, etc.), whereas AIDS is a result of being infected by a virus called HIV (human immunodeficiency virus). There's also a huge difference in how they are treated. Type 2 diabetics take medicine to help them monitor their sugar levels, they have to be careful about their diet and they have to exercise. HIV/AIDS patients have to take medicines that work to try and keep the HIV virus from replicating in their blood (T-cells) and to avoid getting sick - their immune system is seriously depressed.
The answer that fits the blank is the term X-GAL. What is done in a recombinant DNA technology is that DNAs from two different organisms are joined together in order to create a new genetic combination. X-gal is part of gene cloning, therefore, it would be the best to become a selectable marker.
