Answer:
P wave
Explanation:
Electrocardiogram records the strength and timing of electrical activity in heart. As various regions of heart contract at different times and for different duration, the electrical activity is not constant and shows a series of rise and fall. There are three main components of ECG: P wave, QRS complex and T wave.
P wave indicates the beginning of electrical signal in the right atrium. The signal spreads in both right and left atria which leads to their contraction. As a result, blood is pumped into the ventricles and rest of the process occurs.

Answer:
qualitative
Explanation:
<u>Identifying where the barnacle is found of the boat will result in qualitative data, rather than quantitative.</u>
Qualitative data has to do with attributes that cannot be measured but can only be observed, approximated, and characterized, Examples include presence/absence, beautiful/ugly, black/white, etc. On the other hand, quantitative data has to do with attributes that can be measured, such as height, number of leaves, etc.
<em>Identifying where the barnacle is found on the boat has nothing to do with measurement. It only has to do with recording the presence or absence of barnacle in various locations on the boat. Hence, it is qualitative data.</em>
