Given a scientific passage and an answer, generate a question for the given answer.

[Q]: Passage: An autoimmune disease is a disease in which the immune system attacks the body's own cells. Why this happens is not known for certain, but a combination of genetic and environmental factors are likely to be responsible. Type 1 diabetes is an example of an autoimmune disease. In this case, the immune system attacks cells of the pancreas. Two other examples are multiple sclerosis and rheumatoid arthritis. Answer: autoimmune
[A]: What term describes a disease in which the immune system attacks the body's own cells?

[Q]: Passage: Similarly, monoprotic bases are bases that will accept a single proton. Diprotic acids contain two ionizable hydrogen atoms per molecule; ionization of such acids occurs in two steps. The first ionization always takes place to a greater extent than the second ionization. For example, sulfuric acid, a strong acid, ionizes as follows: K a1 = more than 10 2 ; complete dissociation. Answer: accepts one proton
[A]: What is the basic characteristic of monoprotic bases?

[Q]: Passage: As the organism grows more sophisticated, gene regulation becomes more complex, though prokaryotic organisms possess some highly regulated systems. Some human genes are controlled by many activators and repressors working together. Obviously, a mutation in a cis-regulatory region, such as the promoter, can greatly affect the proper expression of a gene. It may keep the gene permanently off, such that no protein can be made, or it can keep the gene permanently on, such that the corresponding protein is constantly made. Both of these can have detremental effects on the cell. Answer: becomes more complex
[A]:
As the organism grows more sophisticated, what happens to the process of gene regulation?
