The unit rate of the train in miles per hour is; 45 miles per hour
Distance traveled by train; d = 540 miles
Time of travel; t = 12 hours
Unit rate here will be the distance travelled per hour.
Formula for the unit rate here is;
Unit rate = distance travelled/time taken
Unit rate = 540/12
Unit rate = 45 miles per hour

Answer:
The statement is true.
Explanation:
The results of the investigations carried out in relation to the link between cortisol secretion and personality reveal differences in the reported evidence. Some of this research indicates that personality traits or disorders play a relevant role in individual differences in the endocrine response to cortisol, both in its basal levels and in the face of stressful stimuli.The relationship between antisocial personality and cortisol levels has been described in several investigations. Among the most reported neuroendocrinological abnormalities in antisocial men is a decrease in cortisol secretion levels. In this regard, Moss, Vanyukov and Martin conducted a case control study comparing cortisol secretion in stressful situations in children between 10 and 12 years of age at risk of presenting aggressive and abusive behavior in adolescence based on their family history. The groups were formed in relation to the presence or absence of a family history of aggression and substance abuse, specifically in the parents. The results found showed that children had a higher risk of antisocial behavior, if their parents had a history of substance abuse and violent behavior, they had lower levels of cortisol secretion in stressful situations than children in the control group whose parents did not present these behaviors negative. The researchers argue that these results could be indicating that a lower increase in cortisol levels in the face of stressful situations could be a biological marker of future antisocial adolescents. Likewise, a longitudinal study with 38 school-age children who had symptoms of aggressive behavior (clinically reported), who were assessed for the circadian rhythm of cortisol in saliva during the second and fourth years of schooling; reported the relationship between the decrease in HPA axis activity and the presence of severe and persistent aggressive behaviors.
Answer:
DNA and RNA are composed of nucleotides that are linked to one another in a chain by chemical bonds, called ester bonds, between the sugar base of one nucleotide and the phosphate group of the adjacent nucleotide. The sugar is the 3' end, and the phosphate is the 5' end of each nucleiotide.
