Use the normal ecg trace below to determine how many seconds the trace represents as well as the heart rate.

mezya [45]

Attached is the image of the concerned ECG reading.

In reading the ECG, first you read the heart rate. To read the heart rate, you must count for the number of small boxes in between QRS complexes, specifically R-R intervals. These number of small boxes will then be used to divide 1500. In this example, there are 20 small boxes between R-R intervals. 1500 divided by 20 is 75, so the heart rate of this ECG reading is 75 beats per minute.

Another way, albeit less accurate, is to count the big squares between R-R intervals and instead of dividing it by 1500, you divide it by 300.

Human beings are responsible for the loss of forest. Why?

Blababa [14]

Beause we cut down a lot of trees. Often, so many, that the health of a forest is irreparably damaged. A forest is not just a bunch of trees. It is a whole ecosystem, in which the trees anchor the growth of many other plant and animal species, hold the ground together to prevent erosion, and produce a lot of oxygen to support animal life. If you harvest too many of the trees, the local ecosystem stops being a forest and starts turning into something else

Name two substances in the body that will move based on the principles of diffusion

almond37 [142]

Two substances in the body that will move based on the principle of diffusion are CARBON DIOXIDE AND OXYGEN.
Diffusion is the process by which molecules of a substance move from the region of higher concentration to the region of lower concentration. Carbon dioxide and oxygen can easily move in an out of the cell via diffusion.
