Answer:
According to the image, the approximate QT interval is 0.4 seconds.
Explanation:
The QT interval is the space between the beginning of the QRS complex and the end of the T wave, which represents from the beginning of depolarization to ventricular repolarization.
Considering that the extandardized measurements of an EKG, where the paper circulates at a speed of 25 mm/s, 1 mm horizontal —measuring time— has an equivalence of 0.04 s.
In the image, there is 10 mm between the beginning of the QRS and the end of the T wave, so:
0.04 seconds X 10 mm = 0.4 seconds.
Then, the estimated QT interval is 0.4 seconds.

The Structural Organization of
Cells. The cell is the smallest matter that still absorbs the characteristics
of life. All cells have three basic parts, a plasma membrane splits each cell
from the environment, permits the flow of molecules across the membrane, and
consist receptors that can affect the cell’s activities. A DNA-containing
region occupies a portion of the interior. The cytoplasm contains
membrane-bound compartments (except bacteria), particles, and filaments & end
ash; all bathed in a semifluid substance. Eukaryotic cells are defined by their
possession of a membrane-bound nucleus. Prokaryotic cells have no defined
nucleus; the only representatives are bacteria.
