Momentum = mass X velocity
<span>The answer is one in four plants had two alleles for the recessive trait. In the F1 generation of Mendel cross, all of the offspring will be heterozygous. After two heterozygotes cross, in the F2 generation, one in 4 plants will have two alleles for the recessive trait, one in 4 plants two alleles for the dominant trait, and 2 in 4 plants will be heterozygotes.</span>
The P wave of the electrocardiogram is considered as a signal from the DEPOLARIZATION of the atria in the heart. This depolarization drives the contraction of the atrial musculature.
An electrocardiogram (ECG) is a device that records the electrical activity of the heart. This record can then be used to diagnose different heart conditions.
The P waves occur when the sinoatrial node generates an action potential which is capable of depolarizing the atria.
This depolarization is then followed by atrial contraction and an increase of the pressure in the atria.
