Answer: That is false, (F), a lot more bad things can happen to you as a result of peer pressure.
The SA Node is the heart's normal pacemaker. When the SA Node depolarizes, electrical signal spreads through the atrial muscle causing contraction.
Explanation:
Inherent rhythmicity / automaticity - The property of the pacemaker cells of the heart to start electrical sequence of depolarization and repolarization.
SA Node or Sino-atrial Node generates the electrical signal.
The electrical signal passes through internodal pathways, atrial fibres, atrioventricular node (AV Node), the bundle of His, Purkinje fibres, right bundle branch, left bundle branch.
Systole - Contraction of cells when the electrical signal of depolarization reaches the contractile cells.
Diastole - Relaxation of cells when the electrical signal of repolarization reaches the myocardial cells.
The correct answer for the question that is being presented above is this one: "A. men naturally have more muscle mass than women and thus need more energy to function." Men and women, regardless of weight, will have different daily energy requirements because men naturally have more muscle mass than women and thus need more energy to function.
Here are the following choices:
A. men naturally have more muscle mass than women and thus need more energy to function.
B. men are more active than women throughout the day.
C. women are smaller than men and have fewer muscles.
D. women naturally have more muscle mass than men and thus need more energy to function.
