Answer: More surfactant is produced as the lungs carry on developing. The blood vessels and lung cells develop and change to increase the amount of surface area available for oxygen to get into the blood. This prepares your baby's lungs to breathe outside the womb.

Emma and her younger brother were running a race. After 30 minutes, Emma started feeling pain in her lower leg muscles. a. Sugge
Georgia [21]

Answer:

This is due to lactic acid accumulation in Emma's leg muscles.

Explanation:

In the absence of oxygen in the muscle cells, the cell switches from performing aerobic respiration to lactic acid fermentation. The lactic acid fermentation produces lactic acid as a product, which builds up in the muscle cells of the body causing a burning sensation and pain. This often happens during exercises.

This is the cause of Emma's pain in her lower leg muscles. Lactic acid has been formed and accumulated in the muscle cells of her leg during the exercise with her brother.
