There are two types of alveolar cells. The type I alveolar cells which lines the alveoli and much more abundant than type II alveolar cells. Then the type II alveolar cells lesser in number but functions differently than type I alveolar cells. Type II alveolar cells secrete surfactant (composed of lecitin and sphingomyelin) for the lungs. Surfactant reduces the surface tension inside the alveoli, preventing alveolar consolidation. This is important as babies with dysfunctional type II alveolar cells (usually preterm babies less than 32 weeks age of gestation) will have respiratory distress syndrome in the absence of surfactant.
When grilling chicken using charcoal fire, the energy transformation that takes place starts from chemical energy, to radiant energy and then thermal energy. The combustion reaction of the charcoal fire converts the chemical energy into heat. The charcoal fire is considered as radiant energy. Lastly, burning fuels like coal or wood produces thermal energy, and that thermal energy is basically the reason why the chicken was cooked even without directly touching the fire.
The nucleus, it is present in eukaryotes but not prokaryotes. Eukaryotes="true" nucleus. Prokaryotes="no" nucleus
C is the answer breaking down inorganic compounds
The dependent variable is the variable which can be manipulated and can affect the independent variable. The dependent variable is on the x-axis while the independent variable is placed on the y-axis. In this case, the x-axis is the number of weeks while the y-axis is the height of the plant.
