many individuals who use tobacco products can become addicted to the___ in those products. that addiction is caused by changes in the brain that are the result. luoa
Many individuals who use tobacco products can become addicted to the nicotine in those products.
That addiction is caused by changes in the brain that are the result of nicotine, the main active ingredient in tobacco products. Nicotine activates the brain's pleasure centers and can produce feelings of pleasure and reward, leading to addiction. Nicotine is known to increase the level of dopamine, a neurotransmitter, in the brain.
Dopamine is the brain's pleasure chemical, which is released during activities such as eating, exercising, and having sex. Nicotine creates an excessive amount of dopamine in the brain, which, in turn, creates feelings of pleasure and reward. This makes the smoker feel more alert and energized.
The brain adapts to the higher level of dopamine by making fewer dopamine receptors. As a result, smokers need more nicotine to create the same effect, which is known as tolerance.
When the brain does not receive enough dopamine, smokers may experience withdrawal symptoms, such as cravings, irritability, and depression. These symptoms make it difficult for individuals to quit smoking, as the brain continues to crave the pleasurable feelings associated with smoking tobacco products.

what are the two bony structures that form the nasal septum
The nasal septum is made up of two bony structures: the vomer and the perpendicular plate of the ethmoid bone. The vomer is a thin, bony, triangular plate which forms the posterior and inferior part of the septum. It articulates with the maxillae and sphenoid bones.
The perpendicular plate of the ethmoid bone is a thin, flat, and square plate that forms the superior and anterior portion of the septum. It articulates with the frontal and sphenoid bones. The nasal septum provides support to the nose, helps to regulate airflow, and allows the structures of the nose to remain symmetrical.
The nasal septum also helps to protect the delicate tissues of the nose from trauma. Its two bony structures provide stability, ensuring that the nose does not collapse under the pressure of air and fluid. The nasal septum also helps to humidify and warm the air entering the nasal cavity, which helps to protect the delicate nasal tissues from dry air and cold air.
Lastly, the nasal septum helps to equalize pressure between the two sides of the nose, which helps to maintain the health of the sinuses and ears.

state of bodily tension, such as hunger or thirst, that arises from an unmet need is description of ?
A state of bodily tension, such as hunger or thirst, that arises from an unmet need is a state of physiological arousal.
Physiological arousal is the body's natural response to changes in its environment, both physical and psychological. This response is triggered by the release of hormones, like cortisol and adrenaline, which create a heightened sense of alertness. This arousal can be caused by anything from the presence of a potential danger to the craving for food or drink. Depending on the degree of arousal, this state can lead to feelings of excitement or tension.
For example, when faced with an imminent threat, physiological arousal can lead to fear and an increase in heart rate and respiration. In contrast, when faced with the prospect of a pleasurable reward, physiological arousal can lead to excitement and anticipation. In either case, once the need is met, the physiological arousal dissipates and the body returns to its normal state.

c thinking about sending your poetry to a magazine
d making a left turn leaving a store and just then it begins to rain
"Thinking about sending your poetry to a magazine" is an example of a response-reinforcer relationship with good contingency but poor temporal contiguity. The option c:
In operant conditioning, the term response-reinforcer relationship refers to the relationship between behaviour and its outcomes or consequences. This relationship is crucial in shaping behaviour, and it is often used in behaviour modification techniques in order to increase or decrease particular behaviours. Temporal contiguity refers to the time between the occurrence of behaviour and the delivery of reinforcement. It means that there should not be a long delay between the behaviour and the reinforcement. Contingency refers to the relationship between behaviour and its outcomes. It means that a particular behaviour must be followed by a particular outcome to be effective. It's the idea that the consequences of a behaviour determine whether or not that behaviour will be repeated or avoided. So, option c: "thinking about sending your poetry to a magazine" is an example of a response-reinforcer relationship with good contingency but poor temporal contiguity. This is because there is a significant delay between the behaviour (thinking about sending poetry) and the reinforcement (getting published in the magazine).

The following are the number of times the data is above and below 8.5: 2.4 + 2.3 + 3.1 + 2.2 + 2.3 + 3.6 = 16.9 > 8.5. Thus, we have 6 values above the median.
1.2 + 1.0 + 1.7 + 1.9 + 1.6 + 2.3 = 10.7 > 8.5. Thus, we have 6 values below the median.
The total number of signs of observations above the median is given as m₁ = 6.
The total number of signs of observations below the median is given as m₂ = 6
The total number of observations is given as n = 16.
The Z test statistic is given as Z = [min(m₁, m₂) - 0.5]/[√(n/2)] = [min(6, 6) - 0.5]/[√(16/2)]≈ 1.5
Using a normal distribution table, the critical value for α = 0.05 is given as zα/2 = 1.96.
Since |Z| = |1.5| < |1.96|, we accept the null hypothesis that the median percent of impurities in this brand of jam is 25%. Therefore, the sign test at the 0.05 level of significance is not significant enough to reject the null hypothesis.
