Answer:
Sympathetic nervous system
Explanation:
The sympathetic nervous system of the autonomic division prepares the body for stress or emergency conditions by generating the “fight-or-flight” responses. The sympathetic nervous system triggers the release of stress hormones from the adrenal medulla to generate the set of physiological responses.
There is dilation of the pupil, and an increased rate of heartbeat and increased blood pressure. Other responses include dilation of airways and dilation of blood vessels that supply blood to skeletal muscles, heart muscles, liver, etc. Under the given emergency condition, the sympathetic nervous system of Meghan was activated to generate the fight or flight response.
OPTIONS:
a. When there are just two other people at the party.
b. When everyone is wearing a nametag.
c. When there are more than 50 people attending the same party.
d. When the need for help from the person who is having a heart attack is very clear
Answer:
c. When there are more than 50 people attending the same party.
Explanation:
Bystander effect is a term used in social psychology to describe the tendency of an individual to intervene in the event of an emergency to offer help to the person needing it, when others are present at the scene of the emergency.
In the case of an emergency just like the scenario stated in the question, where someone develops a heart attack at a dance party, if the party has more people, the slimmer the chance of the person getting help from any of the 50 people at the party, as the presence of others would tend to discourage the any individual from attempting to help the victim having the heart attack.
The situation that would more likely show the bystander intervention effect is <em>"c. When there are more than 50 people attending the same party."</em>
Answer:
Explanation:
Narrow sense heritability - h2
selection differential - S
Selection differential is calculated from the difference between the population average and the parental population.
Breeder's equation:
Response to selection - R = h2S
Mean milk production of 10% cows for experiment = 8.9L/hr
Mean milk production of parental population = 5.1L/hr
Selection differential S= 8.9 - 5.1 = 3.8 L/hr
Response to selection = 0.587 × 3.8 = 2.23
