Textbook Question
Chapter 20, Problem 12P
Biologists have proposed that the use of antibiotics to treat human infectious disease has played a role in the evolution of widespread antibiotic resistance in several bacterial species, including Staphylococcus aureus and the bacteria causing gonorrhea, tuberculosis, and other infectious diseases. Explain how the evolutionary mechanisms mutation and natural selection may have contributed to the development of antibiotic resistance.

Apart from food, plants need other nutrients like water and minerals.
Nitrogen, a mineral, is an important part of all living cells. All organisms need nitrogen in order to grow and repair.
Although nitrogen exists in its elemental form in the atmosphere, it cannot be directly used by plants.
7 Where else can plants obtain their nitrogen from?
Plants make their own nitrogen.
B Plants get it from animals.
Plants get it from the soil.
D
Plants have special structures to break down
atmospheric nitrogen.
