New generations are better suited to their environment than the first generation. What is this called?
olchik [2.2K]

Answer:

Descent with modification

Explanation:

We define evolution as descent with modification from a common ancestor.

Evolution only occurs when there is a change in gene frequency within a population over time. These genetic differences are hereditary and can be passed on to the next generation - which is what really matters in evolution: long-term change. In this process, the new generations are better suited to their environment than the first generation because of descent with genetic modification.

Isovolumetric relaxation and ventricular filling (two phases of the cardiac cycle) take place during __________. Isovolumetric r
Helga [31]

Answer:

Option B, ventricular diastole

Explanation:

Ventricular diastole also termed as ventricular relaxation consists of two phases. In the first phase, the following set of events takes place –  

a) Relaxation of ventricle muscles

b) Reduction in pressure  of blood within the ventricles

c) As this reduced blood pressure gets lower than that of pressure with in the pulmonary trunk and aorta, blood starts flowing back towards the heart.

d) A small dip in the blood pressure is observed at this stage

e) Volume at this stage remains constant as the atrioventricular valves remain closed

f) This phase is known as isovolumic ventricular relaxation phase

In the second phase, the following set of events takes place –

a) Relaxation of ventricular muscle  

b) Dropping of pressure of the  blood within the ventricles lower than that of pressure of blood in the atria

c) Blood starts flowing from atria into the ventricles thereby opening the tricuspid and mitral valves

d) Both the heart chambers chambers are in diastole,  

e) Atrioventricular valves are open

f) Semilunar valves remain closed  

Hence, option B is correct
