If a drug slows down central nervous system activity while increasing the activity of the main inhibitory neurotransmitter in the brain, then it is most likely to be a Depressant.
<h3>
How do neurotransmitters work and what are they?</h3>
Chemical messengers are called neurotransmitters to facilitate communication between nerve cells. Serotonin, dopamine, glutamate, and acetylcholine are a few of them. Numerous processes are controlled by neurotransmitters, including mood, sleep-wake cycles, and appetite.

DEPRESSANTS</h3>
These medications, which are sometimes known as "downers," are available as liquid or colored pills and capsules. As they are intended to lessen the symptoms of mental illness, some medications in this class, including Zyprexa, Seroquel, and Haldol, are referred to as "major tranquilizers" or "antipsychotics." Xanax, Klonopin, Halcion, and Librium are examples of depressants that are frequently referred to as "benzos" (short for benzodiazepines).

It's acellular. it's composed of all the proteins, electrolytes and micronutrients.
Though most prokaryotes have both a cell membrane and a cell wall, there are exceptions such as Mycoplasma (bacteria) and Thermoplasma ( archaea ) which only possess the cell membrane layer. The envelope gives rigidity to the cell and separates the interior of the cell from its environment, serving as a protective filter. Hope this helped!
Generation-to-generation change in the allele frequencies in a population is _____.
a. genetic drift b. natural selection c. macroevolution d. mutation e. Microevolution
Answer:
e. Microevolution
Explanation:
Microevolution refers to the small changes in the allele frequencies and the genotype frequencies of the populations. These changes occur over a few generations and deviate the populations from the genetic equilibrium.
The processes responsible for microevolution are mutations, genetic drift, gene flow, etc. Similarly, sexual selection and nonrandom mating also change the allele frequencies of the populations. Likewise, natural selection brings about microevolution by increasing the frequencies of the alleles that impart the beneficial traits to the organisms.
The answer is C. Raccoons they eat both plants and animals.
