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.

Eric is a 5-month-old baby boy who exhibits signs of loss of muscle function. He has stopped meeting developmental milestones and has lost the ability to do things he could previously do (such as sitting up on his own). He has developed an increased startle response and is less visually attentive. His parents scheduled an appointment with their pediatrician to discuss the symptoms. In taking the patient's history, one of the most revealing pieces of information that the doctor collected was that the family is of Jewish descent

Answers

Answer:

It is possible that Eric has the Tay-Sachs disease

Explanation:

Tay-Sachs disease is a rare inherited disorder that normally appears in infants of 3 to 6 months old. The main symptoms of an infant with Tay-Sachs disorder are the loss of muscle coordination (ataxia), muscle weakness and the loss of motor skills such as, for example, sitting and crawling. The incidence of this genetic disease is higher in people of Ashkenazi Jewish heritage. The Tay-Sachs disorder is caused by mutations in the HEXA gene, which encodes a lysosomal enzyme named beta-hexosaminidase A that is critical for the development of the brain and spinal cord (central nervous system).

What are some advantages and disadvantages of sensory adaptation?

Answers

Answer:

Sensory evaluation makes use of the remarkable virtuosity and range of the human senses as a multi‐purpose instrument for measuring the sensory characteristics of foods. The brain protects itself from an overload of information from the senses by two processes: feature extraction and adaptation. The former involves information reduction by the extraction of selected features from the environment; these form the basis for the reconstruction of the percept in consciousness. The latter, adaptation, involves the attenuation of repetitive and constant input so as not to overload the brain with redundant information.

The effects of adaptation can be observed for all senses. For the chemical senses, the effect is that a constant odor or taste stimulus will be perceived as decreasing in intensity while sensitivity to that stimulus is also decreased. For sensory evaluation, this poses problems. It means that a taste or odor has a tendency to vanish while it is being observed and that sensitivity to subsequent stimuli will be altered. Such sensitivity drift in the human instrument must be anticipated in the design of measurement procedures for the sensory evaluation of food.

Explanation:

Answer: You cannot feel as much so that can be a problem if you get injured but it does help you better understand your surroundings

Explanation: Sensory adaptation refers to a reduction in sensitivity to a stimulus after constant exposure to it. While sensory adaptation reduces our awareness of a constant stimulus, it helps free up our attention and resources to attend to other stimuli in the environment around us.

The diagram shows how fraternal twins (nonidentical twins) form. A pregnancy test checks for the presence of a chemical called HCG that the blastocyst secretes. The HCG levels of some women may be an early indicator of twins. Based on the diagram, why do you think the HCG levels may be different for women carrying twins and women carrying a single child?

Answers

Answer:

If you have just found out that you are pregnant and you think that it may be twins due to high HCG levels twins, ask your OB to conduct further tests in order to deny or confirm this. Keep in mind that a single HCG reading will typically not provide sufficient

Explanation:

Answer:

(You may want to paraphrase this because its the exact sample answer)

Because there are two fertilized eggs, two blastocysts form. So, it’s possible that a woman carrying twins will have higher HCG levels than a woman carrying a single child.
