Rabbits were introduced to Australia by pioneer settlers in the mid-1800s for sporting hunters. They have since stressed native marsupial and plant populations. This is an example of the introduction of exotic species through accidental transport.

Answer the following statements true (T) or false (F)
1. Fermentation is a more efficient form of energy production than aerobic respiration. 2. Substrate phosphorylation occurs when protons pass through ATP synthase and combine with oxygen to make water. 3.
