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.

Answer:
If there is a change in the environment, the particular species which does not manage to adapt either tries to translocate to a different habitat or it perishes. Adaptation requires a long time and does not happen overnight so if there is an option of moving out the animal adapts to do so. If that doesn’t happen we are looking at local extinction of the concerned species. This is one of the reasons why we are facing extinction of several species in our times. The rate at which we are changing the characteristics of habitats and even wiping out certain pristine habitats is leading to extinctions.
