Answer:
A and D
Explanation:
A. Sleep deprivation in turn downregulates dopamine receptors, which makes people more impulsive and vulnerable to drug taking.
D. When a person repeatedly uses drugs, he or she increases the risk for insomnia. This is because continued substance abuse affects the neurochemical functioning of the brain. It disrupts the brain’s sleep-regulatory systems and, in turn, disturbs the latency, duration, and quality of sleep for the user.
Answer: The rejection of the claim about aspirin is more significant as compared to that of vitamin C.
It is because the significant level of aspirin is more dangerous as compared to that of vitamin C.
The dosage of aspirin in the bottle must be accurate as compared to that of vitamin C because it would not cause any harm to the body if exceeded the limits.
It would be wise to use smaller significant level for testing the claim about aspirin.
Answer:
Previous studies have identified several factors that contribute to the accident risk of motorcyclists: sex, age, experience, personality traits, etc. It is for sure that motorcycling represents more than just a mode of motor transportation or sport. It could be a part of riders` personal lifestyle which with other components can contribute to their risk behavior and greater traffic accidents involvement. The main aim of the study was to determine how lifestyle dimensions of male motorcyclists influence the risky behavior of motorcyclists and their involvement in traffic accidents. The set of questionnaires about lifestyle, risky behavior and demographic data were sent by mail to three hundred motorcyclists and two hundred and six participants completed material and sent it back. Results showed that there is a significant correlation between lifestyle and risky behavior of the riders and their involvement in traffic accidents. Also, lifestyle predicts the large amount of the variance of risky behavior and traffic accidents of motorcyclist. We can conclude that life style has an important impact on motorcyclists` risky behavior and traffic accidents involvement.
