Answer:
<u>Methamphetamine</u> is a stimulant that provides an intense high and causes a reduction in the brain's baseline dopamine levels.
Explanation:
Methamphetamine is a drug of abuse, belonging to the amphetamine family, this psychostimulant compound, produces effects such as euphoria and increased energy and concentration. In the long term, when it's consumed chronically, it has other effects, especially at the level of the CNS, such as the decrease in the volume of the hippocampus, producing memory losses associated with the hippocampus and decreased neurogenesis in adults. Dopamine (DA), by acting as a neurotransmitter, it is able to increase neurogenesis in certain areas and decrease it in others. Given the acute intake of methamphetamine, there is an increase in the concentrations of dopamine and serotonin (5-HT), because methamphetamine acts as a substrate for the transporters of dopamine transporter (DAT) and serotonin transporter, therefore reducing the transport of both neurotransmitters.
When there is a chronic methamphetamine consumption, there is a decrease in the concentrations of basal levels of dopamine in the striatum, hippocampus and prefrontal cortex, which is maintained in the long term. It also not only decreases cell proliferation, but also decreases neuronal differentiation and maturation of progenitor cells.
Answer:
Hypertonic
Explanation:
Soda is an example of an hypertonic solution. It is hypertonic in the sense that to make it work for the body, there needs to be a certain amount of water that would be taken from the body for it to be diluted.
The term hypertonic means it is at an elevated concentration than what we have in the regular body.
So to bring it to work, water from the body needs to dilute it. Hence, by bringing water to dilute it, more water is taken from the already thirsty system and thus, the overall effect is that the person that takes the hypertonic solution is left to be more thirstier
Answer: C is the correct answer
Explanation:
The charge by the nucleus of a atom has a negative charge.
Answer:
Enzymes help cells digest food, extract energy from food, and Increases the rate of chemical reactions.
Explanation:
They increase the rate of chemical reactions. Enzymes can be used to break things down, or to make things up.
Without enzymes, reactions in a cell would slow to a halt, to a point where the cell would die.
