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.
<em>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.</em>

7 pea plant traits that mendel had to study
Answer:
First law of thermodynamics is the conservation of energy states that energy is not created and not destroyed but only can be stored.
Thermodynamics second law states that total entropy of a system increases from lower to higher system and some of the energy is always wasted during the work done.
In the food chain plants are the producers which accept light energy and stored in the form of chemical energy and energy flow to the herbivores and higher trophic levels in the chemical form only and no new energy is created in between the chain (Fisrt law of thermodynamics). Heat is generated during respiration by plants and animals (wasted energy) and entropy also increases with the increase in level of the pyramid of energy (Second law of thermodynamics).
Answer:
C
Explanation:
Membranes will allow and inhibit certain ions/molecules. I don't believe it can distinguish whether the molecules are harmful or beneficial!
