If no other changes occurred, how would emigration affect the population density of a group of organisms?​
valentinak56 [21]

<u>Answer:</u>

<em>If no other changes occurred emigration would have a negative impact on the population density of a group of organisms. </em>

<u>Explanation:</u>

<em>Emigration is the movement of a part of population out of an area into a new area. </em>It has a negative impact on the population of the old area and positive impact on the population of the new area.

Population density is the population per unit area that is population per square kilometer.

Thus population density will also be negatively affected by emigration. <em>Hence an area that previously was densely populated might become a sparsely populated area due to emigration.  </em>

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
