Answer:
His findings led to the widespread use of antiseptics such as phenol.
Explanation:
Joseph Lister was a British surgeon. He is not known for being a great doctor, or for having an impeccable surgical technique, but for discovering that the use of antiseptics before and after surgery could save many people's lives. He was a great bacteriologist and knew that bacterial infections were serious, but that they could be prevented with the use of antiseptics. After their discoveries, antiseptics became very popular, among them phenol, which was one of the first to be commercialized and used.
I am going to assume here you are referring to the 'Scramble of Africa' that happened in the second half of the 19th century, as the European power did not really control the African regions before then.
The methods contexts did differ per colonising power and colonised region, but it boils down to the following factors:
- superior firepower, equipment and recourses; having better guns, armour, communication technology, and supply routes, made the Europeans a formidable enemy that the various tribes simply could not counter.
- co-opting the local elites; a tried and tested method for centuries, this has always been the way smart conquerers could maintain control over a region with minimal fuss and expenditur.
<span>- divide and conquer; conflict between the many tribes of Africa has been a constant for centuries in the continent. The Europeans could easily manipulate the various tribes against each other to prevent a unified resistance from rising up. </span>
<span>- a willingness to use extreme forms of terror; the Europeans might have been all high and mighty back home about their Enlightment and democracy, but in Africa they were more than willing to use forms of terror that would make most contemporary dictators feel a little uneasy. Case in point, the widespread killing and mutilation when quotas were not met in king Leopold II's Congo.</span>
These changes are an example of the growth of a forest through ecological succession.
<h3>What is ecological succession?</h3>
Ecological succession refers to the structure in which the species and habitat over an area changes over a given period of time. It is the evolution of the new plants and animals over that area.
The complete question has been attached below.
In the above case, The plant life in the Mount St. helens will evolve again after 100 years which destroyed due to the volcanic eruptions in the year 1980. Thus this process is known as Ecological succession.
Through this process regeneration of the plants and wildflowers will take place and gradually the trees, plants, shrubs, species and creatures will settle there.
