Answer: Ideally, the average heartbeat per minute of an individual is 80 beats per minute.
So if an individual heart's does 80 beats per minutes, then in one hour, that'd be 80 multiplied by 60 minutes, that'd be 4800 beats per hour. In a day, we have approximately 24 hours. Therefore, the total number of heart beat in a day will be 24 multiplied by 4800 which is 115200 heart beats in a day.

Answer:
Firstly, make sure the environment you are in is safe. Are you in a dangerous, or frightening environment? Also, always make sure you are looking out for yourself. Often, we humans, get ourselves into threating situations with loved ones, but we often do not see any red flags, because, as the saying goes, "Love makes you blind." Make sure your environment, and the people you are around are not abusive to anything or anyone around you. This can often lead to very bad circumstances, and just making some of these proactive choices can prevent some very bad things from, happening.

Answer:
b. The rats press the lever least when cocaine is presented.
Explanation:
Reinforcement or reward refers to the physiological processes by which a given behavior, such as drug use, becomes habitual. This occurs when neurons release the neurotransmitter dopamine to the nucleus accumbens (NAc) after drug use.
In tobacco, nicotine is the main component triggering of the reinforcement. Once inside the brain, nicotine activates nicotinic receptors, which in turn contributes to the reinforcement mechanism. Following repeated exposure to nicotine, a neuroadaptation process is established for some (but not all) effects of nicotine. Increased brain nAChRs (acetylcoline receptors) are observed in response to desensitization of these nicotine-mediated receptors. This desensitization can play an important role in the development of tolerance and dependence.
The fact that nicotine is a weak reinforcer, means that maybe the rat already had an neuroadaptation with this drug, not feeling anything with this drug anymore, and thats why he would prefer other drug, like cocaine, pressing the lever of nicotine less often.
