The structures of the respiratory membrane. Concept introduction: The respiratory system is the biological system that consists of specific organs and structures used for the gas exchange in animals. The processes of the pulmonary system include the transport of air into or out of the cell, the transport of the air spaces in the lungs and the blood stream, and the transport of the blood into and out of the capillary beds of the lungs to the body organs and tissues.

In a natural population of outbreeding plants, the variance of the total number of seeds per plant is 16. From the natural population, 20 plants are taken into the laboratory and developed into separate true-breeding lines by self- fertilization-with selection for high, low, or medium number of seeds-for 10 generations. The average variance in the tenth generation in each of the 20 sets is about equal and averages 5.8 across all the sets. Estimate the broad-sense heritability for seed number in this population.
