Isovelumetric relaxation and ventricular filling take place during Ventricular diastole.. Both occur during ventricular diastole when the ventricles are not actively contracting and ejecting blood. Ventricular diastole is the period during which the two ventricles are relaxing from contortions of contraction, then dilating and filling; atrial diastole is the period during which the two atria are relaxing, dilating, and filling.

Answer:
Human nutrition is the process of which substances are Transformed into tissues and energy which are used up to mental and physical activities!
Answer;
C) the amount of time that the two species have been evolving apart
Explanation;
-Scientists can use relaxed-clock methods to deal with variation in the rate of the molecular clock. By measuring the patterns of evolutionary rate variation among organisms, they can also gain valuable insight into the biological processes that determine how quickly the molecular clock ticks.
- The molecular clock hypothesis states that DNA and protein sequences evolve at a rate that is relatively constant over time and among different organisms. A direct consequence of this constancy is that the genetic difference between any two species is proportional to the time since these species last shared a common ancestor.
