Answer:
Africans were forcibly brought to British-owned colonies in the Caribbean and sold as slaves to work on plantations. Those engaged in the trade were driven by the huge financial gain to be made, both in the Caribbean and at home in Britain.
Answer:
The pie charts tell a similar history: services are the dominant economic sector in all countries, industry comes second, and agriculture lags behind in third place.
Explanation:
However, the situation is not the same for all countries. Western European Countries like France and Italy have much larger services sectors, and much smaller agriculture sectors than Eastern European Countries like Romania and Poland.
This is because as countries become more developed, their services and industry sectors tend to grow at the expense of the agricultural sector, and Western Europe is more developed than Eastern Europe.
Answer:
2. Bacteria that have a zone of inhibition are considered susceptible to the tested drug.
3. Bacteria that lack a zone of inhibition are resistant to the tested drug.
4. This test determines if a bacterium is resistant to a specific antibacterial drug.
Explanation:
The Kirby-Bauer test is a technique used in laboratories to assess the sensitivity of bacteria to antibiotics. This is one of the most reliable sensitivity tests in the world and is used in several areas such as health, agriculture, zoology, among others.
The test is done by applying antibiotic discs to a petri dish containing culture medium and a growing bacterium. When the bacterium grows inside the plate, it is observed whether the antibiotic discs were able to cause zones of inhibition of this growth.
Bacteria that do not have zones of inhibition are considered resistant to antibiotics, whereas bacteria that have zones of inhibition are considered susceptible.
