Answer: Stabilization selection
Explanation:
Natural selection involves the differential survival and growth of organisms which have suitable traits to survive in unfavorable or adverse environment. Such traits are passed on to the next generation. Stabilization selection is a type of natural selection in which the nature selects the non-extreme phenotypic traits. Middle traits are selected and such organisms grow and reproduce. Example can be given that of human babies in which babies with low weight lose more heat and babies with high weight are difficult to be delivered from the pelvis. Therefore, babies with middle weight are expected to survive more than that of low or middle weight.
Answer:
A. Aorta
B. Pulmonary Artery
C. Pulmonary vein
D. Left atrium
E. Mitral valve
F. Lift ventricle
G. Right ventricle
H. Tricuspid valve
I. Inferior vena cava
J. Right atrium
K. Pulmonic valve
L. Superior vena cava
Explanation:
Aorta is big artery which takes blood from the heart and gives it to all body. Pulmonary artery carries deoxygenated blood from the heart to the lungs while pulmonary vein carries oxygenated blood from the lungs to the heart. Mitral and tricuspid valves prevent the backward flow of blood in the heart. Superior and inferior vena cava is a big vein which collects deoxygenated blood from all body.
