The difference in crocodiles and alligators is in their snouts.
Answer:
True
Explanation:
The finches Darwin discovered are genetically different from other finches of the same species because of differences in habitat climate and the habitat itself.
The correct answer is none of the above.
Bacterial cells can transfer genetic material through a process called bacterial conjugation. This process involves the direct physical contact of the bacterial cells and a horizontal gene transfer. The genes which are transferred are most of the times beneficial for the recipient, such as genes for antibiotic resistance.
In this example, bacterial cells cannot have physical contact, since they are separated by a glass filter. Therefore, the bacterial conjugation cannot happen. Given that no gene transfer can be achieved, the AY strain remains bio- trp- and is unable to grow on any medium that lacks bio or/and trp.
The majority of the accessible drinking water on our planet comes from glaciers.
