An increase in alcohol consumption
Alcohol can boost GABA activity in the brain in one of two ways: either by acting on the presynaptic cell, which increases GABA release, or. It can influence the postsynaptic (i.e., signal-receiving) neuron, promoting the GABAA receptor's activation.
The brain circuits that regulate motivational processes, such as arousal, reward, and stress, are altered by chronic alcohol consumption. These modifications impact systems that use dopamine, opioid peptides, -aminobutyric acid, glutamate, and serotonin as signaling molecules as well as systems that control the brain's stress response. Frequent episodes of intoxication, obsession with alcohol, use of alcohol in spite of negative effects, and a need to seek out and use alcohol are all signs of alcoholism developing.

I believe it is gel electrophoresis.
Gel electrophoresis is a techniwue used to separate DNA fragments or other macromolecules such as RNA and proteins based on their size and charge. It can also determine the actual size of a piece of DNA by examining it next to a standard "yardstick" made up of DNA fragments of known sizes.
I believe that B is the answer. There are actually multiple disadvantages to using solar energy including the lack of reliablility, the amount of resources needing to be used to create solar panels, and even the lack of energy when there is no sun.
The reduced dependence on fossil fuels is an advantage and the same is involved when it comes to choice C. It is also important for it to become a renewable source so there isn't a lack of needed resources.
The correct answer is segmentation. <span>The annelids also known as segmented worms, are bilaterally symmetrical invertebrate organisms. Their main characteristic is a segmented body. Annelid's body consists of segments that are identical (except the first and the last one), having the same sets of internal organs and external chaetae. Septa separate the segments and enable the annelids to change the shapes of individual segments, which facilitates movement by peristalsis (symmetrical contraction movement).</span>
