Answer:
Sadie's continue use of marijuana will lead to her brain's reduction of the neurotransmitter anandamide which will require her to need more of the marijuana to achieve its effects.
Explanation:
The active ingredient of marijuana is tetrahydrocannabinol (THC)which is responsible for causing change in the brain.
This activates specific receptors called cannabinoid receptor.This receptors are found in limbic and cerebral cortex region and cerebellum.
As these receptors are located in the brain, the effect of these receptors are also wide spread.In healthy brain, these receptors are activated by a neurotransmitter called as anandamide that have pain relieving effect and also play important function in brain.When THC activates these receptors,causes interference of the normal function.
marijuana also boost another type of neurotransmitter called dopamine after taking the drug.
Answer:
It is necessary to make the following assumptions when making inferences about a group of people based on a sample of subjects drawn from that group:
- Data is quantitative in nature.
- A sample size of 30 or more is required.
- The data set must consist of a simple random sample.
- A Normal Distribution must be present in the data.
The data must come from a sample that isn't all the same size so that it can be generalized well.
The sample size must be at least 30 or more, according to the central limit theorem.
Mean and standard deviation are two examples of quantitative data from which statistical conclusions can be drawn.
To avoid bias, the sample size should be increased rather than the distribution skewed.
