Professor Snape plans to conduct a study of physical activity in 2nd to 5th grade children for his masters thesis.  The study is to be conducted over a single school year.  He is interested in determining whether the frequency of physical education classes affects children’s tendency to engage in physical exercise.  Within each grade, two classes are randomly selected and assigned to one of two conditions.  In condition A, students participate in PE for 30 minutes, four days a week (4x/week).  In condition B, students participate in PE for 60 minutes, two days a week (2x/week).  During the final month of the school year, Professor Snape has six undergraduates who are members of his research team observe children during recess.  The observers are given a list of 10 children each day.  They are told to observe each child for 3 minutes and to record how long (minutes and seconds) the child spends engaging in physical exercise during that time.  He defines exercise as moving (running, walking, climbing, or jumping). Professor Snape’s hypotheses are: children in 5th grade will be less physically active than children in 2nd grade children who take PE 2x/week will be less physically active than children who take PE 4x/week study, grade is a(n) In this study physical activity   is a(n)

Membrane proteins have a variety of functions.  What type of membrane protein would have a role in which it would bind to a specific molecule such as a hormone or an enzyme?

Children of mothers who abused alcohol during pregnancy often have attention deficits. Researchers introduced 2 methods in hopes of finding ways to improve the alcohol-exposed children’s ability to pay attention in the classroom. They studied 20 alcohol-exposed 9- to 12-year olds compared with 20 alcohol-unexposed 9- to 12-year olds. The participants were matched and randomly assigned to 2 groups. Group 1 was instructed on how to improve working memory, while Group 2 was given instruction on how to eliminate distractions.   The outcome measures were engagement, disengagement, and shifts in attention during a series of discrimination tasks     This study above is a __________________ because ____________________.

The following is an explanation of the sequence for _____________________________. 1) Hormone or neurotransmitter binds to receptor.2) Receptor activates G protein. 3) G protein activates (or inhibits) adenylate cyclase.4) Adenylate cyclase catalyzes production of cAMP from ATP.5) cAMP activates a protein kinase.6) The kinase activates or inactivates enzymes.7) The appropriate cellular occurs in response to the hormone or neurotransmitter.

A researcher measured how much violent television children watched at home. These children were also observed for their aggressiveness on the playground. The researcher found that as the amount of violence watched on TV increased, the amount of playground aggressiveness increased. The type of relationship found was
