Answer:
Ethel is correct because energy is not carried from one place to another.
It is a transverse wave.
Explanation:
During the propagation of waves from one point or place to another, energy is being transferred. Thus, when one's hand is being waved, there is no transfer of energy from one point to another. Therefore, Ethel is right while Brody is wrong.
A transverse wave is known as a type of wave that the direction of propagation is perpendicular to the vibration of the medium. Therefore, the wave is a transverse wave.
Answer:
1. Ventricular depolarization −−QRS complex
2. Total time it takes for the ventricular muscle to depolarize and repolarize −−QT interval
3. Atrial depolarization −−P wave
4. Conduction through the atrioventricular (AV) node −−PR segment
5. Ventricular repolarization −−T wave
6. The ventricles are in their depolarized state −−ST segment
7. Conduction through the atrioventricular (AV) bundle −−Q wave
Explanation:
ECG or electrocardiogram is the graphical representation of the heart's rhythm and electrical activity measured by electrical signals. The contraction of the heart shows electrical activity.
There are various deflections shows from baseline and known as specific waves and there are also some flat lines between waves called intervals. This atrial depolarization is called P wave and ventricular repolarization called T wave and the time between ventricular muscles depolarization ( QRS complex) and repolarization is QT interval. Conduction through the atrioventricular (AV) bundle is known as Q wave.
Mitochondria is the powerhouse of the cell. It converts food into energy the cell can use to help keep all the cells in the body functioning.
I believe D because if the fertilizer had a concentrated source of nitrate (which plants do need) then when watering that can go into the ground water which is underground <span />
Hello.There are 5 levels of cell organization recognized by biologists The 5 levels consist of :
