Answer:
The chemical components, which are utilized to eradicate or eliminate pathogenic microbes are known as chemical disinfectants. These comprise sodium hypochlorite, chlorine, bromine, hydrogen peroxide, chloramines, and others.
Traditionally, the chemical disinfectants are usually compared with phenol as phenol was the first or the foremost used chemical agent for the purpose.
Answer:
Correct answer is A. "making future predictions about plant behavior "
Explanation:
The most important part of the question is "overcrowded area" which leads to the future concerned scenario of modern societies. We know that, in future, the supply of resources/nutrients will be limited and thus we want to develop sustainable practices. For this, scientists often carry out the experiments where the organisms are forced to live/grow in a crowded area and then we understand how each individual responds in the presence of limited resource supply. In this experiment, I perceive that the scientist is doing a similar kind of study for a specific plant which will help him assess the future concerns of growth and development for that species as well as its interaction with the environment.
I don’t see any labels, but remember that humans are a great example of a k-selected species. High rates of parental care leads to high survivorship of offspring, and thus negates the need to have large amounts of offspring.
R-selected species are quite the opposite. They produce large amounts of offspring at many intervals in an attempt to maximize survivorship, as they don’t have strong parental involvement with their young. Think of insects.
