Hi there!
The example of the meadowlarks is an example of behavioral isolation. This is because the mating call is a behavior the birds exhibit. This helps the birds to find their correct mate because though the birds look similar, they are not able to produce offspring.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
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.

Explanation:
Density, the weight of an object divided by its volume, is a property of all matter, including solids, liquids and gases. The value of an object's density depends on what it's made of as well as its temperature; for example, lead weights are denser than feathers, and cold air is denser than hot air.
The number of weight gained in pregnancy should be different based on the BMI. Assuming Sadie BMI is 25-29.9kg/m2 then the normal weight gain for single pregnancy would be 15 to 25lbs.
Higher BMI will cause the normal weight gain become lower. For BMI >30kg/m2 normal weight gain would be 11-20lbs
