Answer:
The conclusion is false, because it is assuming that correlation = causation.
Explanation:
An important principle in statistical analysis is the principle that when correlation exist between two variables or more, it does not mean that one of the variables are causing the other to appear in a certain manner.
Remember that correlation means that you are investigating whether a relationships exists between two variables; in this example, as we can see, it is between the biodiversity in an ecosystem and the population of an insect.
The graph can be said to illustrate the result of the research; that as the biodiversity of the ecosystem goes down, the insect's population goes up. This is a form of negative correlation.
However - we do not know what is the direction of the relationship; the student concludes that as some insects die within the ecosystem, the researched insect's population goes up; assuming that the predator species died off and thus the researched insect's population increases.
Yet, it is also possible for the relationship to go towards the other direction; the researched insect population increases - perhaps by the introduction of a new food source that causes the species' population to increase - and thus, this damages the biodiversity of the ecosystem, making the population go down since it is possible that the researched insect is instead the species which is on top of the food chain at that ecosystem.
To investigate the direction of a relationship, further research need to be done and more sophisticated statistical methods need to be used.
<span>When it comes to helping others, humans help both kin and non-kin, while other animals tend to help kin only. The answer is letter A. Humans, male and female are of the same species and therefore, it is natural for them to help each other. Unlike for animals, they only help their own kin, this is mainly due to their protectiveness against predators.

Answer:
more than 50 percent.
Explanation:
In 2008, more than 50 percent of the total population of earth lives in urban areas because people come to urban areas in order to earn money for their family and achieve higher status in the society. In 2030, about 60 percent of population of earth will live in urban areas. There are a lot of opportunities of jobs in the urban cities while with the increase in population, the rural areas are also converted into urban areas.
