Is the dose-response relationship for most psychoactive drugs characterized by a threshold model or a linear model? Explain your answer.

Expert Solution

Answer:
The dose response relationship/exposure response relationship exhibit the variation effect on a species due to varying categories of exposure to stressor (physical or chemical) after a particular time of exposure or food.
It is applicable to individuals.

For example small quantity create very little effect, a huge quantity create fatal effect)
Dose–response relationships basically depend on the exposure route and time. Responses due to different time exposure and routers exhibit different relationship and results on the impact of stressor. after a different exposure time or for a different route leads to a different relationship and possibly different conclusions on the effects of the stressor under consideration. These limitation are due to the complexity of biological systems & biological processes .
A threshold model or linear model states that certain dose of a psychoactive drugs is dangerous and doses below the limit is safe. This model is generally applicable to psychodrugs health hazards.

Consider a problem in pharmacokinetics concerned with the dose-response relationship of a drug with its rate of clearance λC^2 , where C(t) denotes the concentration of the drug in a patient ’s body at time t. Let C_0 be the concentration at time t = 0, then dC / dt = −λC^2 . (1) Now suppose constant doses C_0 are given at equal intervals of time T. (a) Find the amount of drug in the body immedately after the n...

A paper suggests that the simple linear regression model is reasonable for describing the relationship between y = eggshell thickness (in micrometers, µm) and x = egg length (mm) for quail eggs. Suppose that the population regression line is y = 0.115 + 0.007x and that σe = 0.005. Then, for a fixed x value, y has a normal distribution with mean 0.115 + 0.007x and standard deviation 0.005. Approximately what proportion of quail eggs of length 14 mm have a shell...

1. A simple linear regression model is an equation that describes the straight-line relationship between a dependent variable and an independent variable. T or F 2. The residual is the difference between the observed value of the dependent variable and the predicted value of the dependent variable. T or F 3. The experimental region is the range of the previously observed values of the dependent variable. T or F

Number 1 Say that you want to use simple linear regression to model the relationship between the explanatory variable x= the number of alcoholic drinks consumed per week, and the response variable y= number of hours of exercise per week. You collect data on n=52 people, and find the regression line ŷ=10-0.3x. (2 pts) What is the theoretical model underlying your regression analysis? (4 pts) Say that Lorenzo has six alcoholic drinks a week. Predict how many hours he will...
