Is this statement true or false? according to the 2008 national institute of child health and human development (nichd) nomenclature, there are four categories of fetal heart rate variability: absent, minimal, moderate, and marked.

Option-(True):

There are four categories of fetal heart rate variability or changes(As the variability in heart rate lasts for 10 minutes, either it will increase or decrease): absent, minimal, moderate, and marked.

Explanation:

Baseline Variability:

The analyses of the heart beat rate is done upon the consideration of two consecutive cycles of the heart beating. As the 2 cycles are measured with comparison of the data with the standards present.

As the fluctuations or variability inside the heart rate is analysed on the basis of the the "Amplitude range" of the signal generated from the heart pulses or beats(Amplitude is defined as the "distance" of the signals vertical point from that of its points near its initiation or origin.)

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
