4. It is a way to identify living things and it helps us understand how living things may be related.
5. Within an area some bacteria will have a plamid that codes to be resistant. When antibiotics are introduced to the area, the bacteria that doesn't have the plasmid is more likely to die, making the population more resistant. (similar to the bottleneck effect) Bacteria becomes antibiotic resistant if it exposed to antibiotics and survives as a bacteria without the plasmid. This plasmid can be shared through sexual reproduction (Horizontal gene transfer)

2. Natural selection is the process of evolution that favours the reproductive success of some individuals over others. Artificial selection is the directed breeding of individuals of favoured traits that are chosen as parents for the next generation.
3. Micro evolution: Evolution within a population as a result of adaption.
Macro evolution: Evolution which results in the formation of a new species.

3. The circulatory system is responsible for the inhalation and exhalation of oxygen and carbon dioxide, respectively. The alveoli in the lungs perform gas exchange, during which carbon dioxide is expelled from the blood stream and oxygen is taken into the blood stream. The heart, in the circulatory system, is reponsible for both pumping non-oxygenated blood and oxygenated blood to the lungs for exhalation and from the lungs to the various parts of the body.
