Describe how an ecg can an informed individual determine the health of the heart.2) if an individual is experiencing a heart rate of 30 beats per minute and a p wave is missing in the ecg reading, what might be a logical conclusion about this individual’s heart?

ECG measures the electrical activity of the heart and how the I pluses travel through the heart... There by showing when the heart is beating normally or abnormally.. It can show an informed mind all this.

2.There are many causes of these but hyperkalemia ie high amounts of potassium in the blood can be a cause

Explanation:

the correct option is option d

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
