In a field study on jet lag, a condition created when the body's rhythm lags behind or ahead of the time of day it would be at the person's place of departure, the hypothesis was that the body's reactions of fatigue, dizziness, stomach aches, and mental confusion were caused by the rhythmic changes rather than just from the fatigue of flying. One group flew to China, crossing several time zones. Another group flew an equal amount of time and distance, but crossed NO time zones.
In the study above, what was the independent variable?
a) The group that does not fly to Asia
b) The group that does not fly at all
c) Fatigue, trouble making decisions, dizziness, stomach aches
d) The alteration of the light-dark cycle from the time-changing flight path

Answers

Answer 1

Answer:

In a field study on jet lag, where one group flew to China, crossing several time zones. Another group flew an equal amount of time and distance, but crossed no time zones, the independent variable is the alteration of the light-dark cycle from the time-changing flight path.

Explanation:

In a research study, the independent variable is one that can be manipulated to produce an effect on the dependent variable, effects that can be measured or quantified.

In the proposed case, the independent variable is alteration of the light-dark cycle from the time-changing flight path, since this determined which group travels through different time zones, and which group makes the flight without changing time zones. In the first group it can observe the appearance of Jet lag, and its symptoms, as a result of the time-changing flight path.

The other options are not correct, due to Ñ

    a) The group that does not fly to Asia  are the research subjects.

    b) The group that does not fly at all is not included in the study

    c) Fatigue, trouble making decisions, dizziness, stomach aches are effects of Jet lag, the dependent variable, whose appearance is the result produced by the independent variable.

What steps would you take to keep yourself safe from bullying? Write a short paragraph about these strategies.

Answers

To be safe from bullying, you first need to have a good background, that means you can’t be known as the kid who nobody likes, and you also need to defend yourself or ignore them, as that is what makes them stop. You can also get people you trust to defend you, friends, family, etc. if your getting bullied the best possible way to stop it, is ether put your foot down, or tell a adult. Some adults will not help you, however, usually not giving them a reaction will get them to stop, but if the EVER put their hands on you, by all means, put them where they belong.

In a field study on jet lag, a condition created when the body's rhythm lags behind or ahead of the time of day it would be at the person's place of departure, the hypothesis was that the body's reactions of fatigue, dizziness, stomach aches, and mental confusion were caused by the rhythmic changes rather than just from the fatigue of flying. One group flew to China, crossing several time zones. Another group flew an equal amount of time and distance, but crossed NO time zones. Which group would be the experimental group, most likely to suffer symptoms of jet lag?
a) The group that did not cross any time zones
b) Neither
c) Both groups
d) The group that flew to Asia

Answers

Answer:

The group most likely to suffer symptoms of jet lag is the group that flew to Asia (option d).

Explanation:

In the study, the group that traveled to Asia not only experienced exhaustion by flight hours, but also experienced jet lag. The other group, upon completion of the extended flight, remained in the same time zone.

Jet lag is an alteration in a person's physical conditions, due to a mismatch in their circadian cycle, when a person travels to a country with a different time schedule. Jet lag, especially when traveling between America and Asia, tends to alter a person's light-dark cycle, resulting in unpleasant symptoms:

FatigueNeurological symptoms such as headache, mood swings, dizziness and confusion.Digestive symptoms such as vomiting, abdominal pain and diarrhea.

It is very likely that the time changes have produced symptoms on the trip to Asia, compared to the group that did not go through different time zones.

    The above reasoning explains why the other options are not correct.

Do you agree with the practices of the majority of U.S. adults, who use physical punishment to discipline their children? Has your opinion changed as a result of studying child development ? Explain

Answers

Personally I think that physical punishment to a degree is okay but not excessive physical punishment. I think that over use of this type of punishments could lead to problems.
I think physical punishment has a negative impact on a child especially at a young age. Let’s say you discipline you young child he’s 7 you punish him in a physical way that going to impact the way he sees discipline. As he grows up he might remember this is a harsher way. And then when he has kid the physical discipline could possible be worse then the discipline you provided. (This is just my personal opinion and how I would answer the question)
