Multiple Choice

Use the following to answer questions
Scenario I
The following scenario is based on and presents fabricated data consistent with the following study:
Caspi,A. ,Sugden,K. ,Moffitt,T.E. ,Taylor,A. ,Craig,I.W. ,Harrington,H. ,McClay,J. ,Mill,J. ,Martin,J. ,Braithwaite,A. ,and Poulton,R.(2003) .Influence of life stress on depression: Moderation by a polymorphism in the 5-HTT gene.Science,301(5631) ,386-389.
The serotonin transporter gene codes for the serotonin transporter,a protein that transports serotonin from the synapse to the presynaptic neuron.Several polymorphisms of the gene exist,including a "short" (s) and a "long" (l) variation.As humans receive one copy of the gene from each parent,people can be grouped into three groups based on this genetic variation: s/s (two copies of the short gene) ,s/l,and l/l.Caspi et al.(2003) interviewed participants in each of these groups and asked them a wide range of questions to determine both the degree of exposure to stress and the number of depressive episodes participants had experienced in their lives.Fabricated results consistent with their major findings are shown in Figure 3.1.

• A)recycles
• B)releases
• C)synthesizes
• D)metabolizes

Definitions:

Low Pressure

Refers to situations where the pressure within a system or component is below the normal operating level, potentially indicating a problem.

High Pressure

Pertains to a condition where the pressure in a system or container is significantly above atmospheric pressure, often used in hydraulic or pneumatic systems.

TXV

Thermostatic Expansion Valve, a device in air conditioning and refrigeration systems that regulates the flow of refrigerant.

Suction Lines

Pipes that transport refrigerant from the evaporator towards the compressor in a refrigeration system.
