What could have caused this situation? Lisa has always been a heavy drinker. These days, she doesn't show any signs of frankness, such as euphoria or dizziness, even after consuming a lot of alcohol. She has probably developed to alcohol

She has probably developed a high tolerance to alcohol.

Explanation:

Tolerance occurs when someone repeatedly uses alcohol or other drugs like Lisa has. Over time, the body no longer reacts to the substance the same way it did the first time the person consumed it this may be why she is not showing any sings of frankness. With increased tolerance, the brain may not feel euphoria or dizziness.

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.    

due to the fact that it skipped a generation we can tell it is definitely not a dominant trait, therefore it must be recessive. i think this is right let me know!
