Answer:
b. Start at the inferior region of the heart and remove the parietal pericardium until you reach the atria, then carefully cut the inferior portion of the parietal pericardium off. After you have done this you can slowly expose the major vessels by removing the rest of the parietal pericardium.
Explanation:
The pericardium is a fluid-containing membrane that surrounds the heart and protects it from infections while also lubricating it during movement. Pericarditis is a condition in which the pericardium becomes stiff and holds the heart in such a way that it prevents normal pumping movement, filling the heart inconsistently with blood and causing heart failure. To solve this, pericardiectomy is performed which is the surgical removal of the pericardium. This is done through median sternotomy, this approach cuts through the breastbone to reach the inferior part of the heart and then the parietal pericardium which is the outer pericardium.
Answer:
Imaginary audience.
Explanation:
Although you tried to help, he was inconsolable. Your nephew was experiencing what David Elkind regarded as<em> the imaginary audience</em>. David Elkind proposed this psychological term to refer to the feelings that adolescents experience. Adolescents feel that they are under constant surveillance of family, and peers. This is the reason why this adolescent is inconsolable.
In assessing the internal validity of an intervention, we try to determine if certain changes cause certain outcomes. It is relevant in studies that try to establish casual relationship. While in observational or descriptive studies, it is not that relevant. It is also possible to have internal validity in a study and not have construct validity. Example, imagine a study where you are looking at the effects of a new computerized tutoring program on math performance in first grade students.
The correct answer is C. Weather conditions change rather quickly (sunny one day, rainy the next), while the climate of a region is fairly set in stone for many years.
A is wrong because weather conditions only take minutes to change (technically), and climate changes take years and years.
B is wrong because weather is the one that describes specific conditions (partly cloudy with 70% chance of ran...), not climate, which is more average.
And lastly, D is wrong because climate conditions change so slowly that we have plenty of time to predict it, think of our climate changes today. Weather conditions are not consistent from year to year (could have rained on your birthday last year, it doesn't mean it will rain on your birthday this year).
Good luck! :)
