Answer: Which statement describes the condition of the heart at the point indicated in the electrocardiogram?

  • The atria are contracting and pushing blood into the bottom ventricles of the heart.

Explanation:

The electrocardiogram is a test that records the electrical activity of the heart. <u>Each beat produces an electrical activity </u>and with an electrocardiograph we can see how that activity is and if there are alterations of the heart rhythm.

The P wave is the first wave of the cardiac cycle.<u> It represents the depolarization of the atria.</u> It is composed of the superposition of the electrical activity of both atria.

Its initial part corresponds to the depolarization of the right atrium and its final part to that of the left atrium.

borishaifa [10]

Answer:

Microvilli function to increase the functional absorptive capacity of the small intestine cells

Explanation:

Microvilli cover the apical surface of the intestinal absorptive cells, (i.e., enterocytes), thereby increasing the surface absorption area of the small intestine from 20 to 1000-fold. Microvilli are numerous projections that have only one dimension beyond 100 nanometers (nm) and form a fingerlike brush border.  In a similar manner to the experiment that involves two papers towels contacting two cups of colored water, this formation can significantly increase the velocity of absorption because the colored water molecules have higher surface to move faster from the cup that is in contact with the paper in a zigzag way.
