Answer:
I am 99% the answer is A. Darwin did not discover Archaea, Evolution does NOT happen in a straight line, and variation is totally different than evolution.
Explanation:
The tracing of uterine activity measured with a solid-tipped intrauterine pressure catheter (IUPC) depicts no contractions. However, you are palpating contractions that are strong in intensity with a frequency of every 3 minutes and a duration of 60 seconds. A possible cause for this finding is (select an answer): The connections to the system are not connected.
An IUPC counts the number, length, and force of contractions. During palpations peaks of strong intensity is recored.As in this case IUPC seems to be not connected as its near impossible to get no contractions when palpation are high.
And one unit is the amount of pressure required to raise a mercury column by one millimetre. The intensity of the contraction is assessed from the baseline (when the uterus is relaxed) to the rise of the contraction and is recorded in units. According to studies, after spontaneous labour, 200 units of contractions per 10 minutes are typically sufficient for vaginal birth.
