I believe the correct answer is serotonin

<h2>Explanation: </h2>

Antipsychotic drugs are use to treat psychosis brought by any psychotic disorder for example the condition called schizophrenia. They can also be used to treat manic episodes of Bipolar disorder. The antipsychotics are divided into first-generation antipsychotics and second-generation antipsychotics with different outcomes.

<h2>Further Explanation: </h2>

Second-generation antipsychotics are also known as atypical antipsychotics but with minimal side effects and they have some efficacy that is almost the same to the first generation antipsychotics. The second generation antipsychotics bind antagonistically to the dopamine D2 receptors and also bind to serotonin 5HT2 receptors. They have more affinity to these 5HT2 receptors than the dopamine D2 receptors and this is the reason why they have less side effects compared to the first-generation antipsychotics. Binding antagonistically to the receptors will help reduce the symptoms and the intensity of the extrapyramidal symptoms that are experienced. Examples of second generation antipsychotics include Asenapine, Clozapine, Lurasidone, Risperidone and Olanzapine. Clozapine is the most common drug in this category and binds weakly to the dopamine D2 receptors and more strongly to the serotonin 5-HT2 receptors. It has a half life of 12 hours. Due to these drugs binding to the alpha 1, alpha 2 and H1 receptors, they bring about side effects such as postural hypotension. Others such as risperidone cause high levels of prolactin that may cause galactorrhea. Use of these second generation antipsychotics predisposes elderly users to increased risk of stroke. All side effects include seizures in overdoses, sedation, urinary retention, postural hypotension, sexual dysfunction due to the hypotension that affects erection, cardiac arrhythmias and in fatal instances myocardial infarction, dry mouth and extrapyramidal symptoms that are similar to Parkinson's i.e. rigidity, bradykinesia and tremors that start a few weeks after the start of dosages for these drugs. Weight loss is miscellaneous and is not so common to users.

What are possible negative effects of building a hydropower dam? Select the two correct answers.

MrMuchimi

The correct answers are B; Displacement of people living near the proposed dam and C; Lower river water levels in other areas.

Further Explanation:

The hydropower dam uses water instead of coal to generate electricity. Since they are build on the water, they will be using that source as a way to generate electricity. This will cause the water levels to be lower in some areas along the river.

When building a dam, they will need to use property that is located on the river. Many people own homes along the river banks all over the world. The company who will be building the dam will usually buy out the property owners at a fair market price. This will mean that they will have to move and leave their homes. The homes are typically torn down to make way for the dam.

In some instances, the water bills for the people in the area may be raised also since so much water is being used by the hydropower dam.
