<span>Experiments</span>
An experimental research entails a
controlled test of a cause-and-effect relationship that researchers suspect
exists. Experiments involve a researcher directly controlling or manipulating
changes in the independent variable by exposing participants to the treatment
conditions. It is undertaken to make a discovery or test a hypothesis
Answer:
his laws were brutal.
Explanation:
The Hammurabi code of laws, a collection of 282 rules, established standards for commercial interactions and set fines and punishments to meet the requirements of justice. Hammurabi's Code was carved onto a massive, finger-shaped black stone stele (pillar) that was looted by invaders and finally rediscovered in 1901.
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.

<h3><u>Answer;</u></h3>
Suffix
<h3><u>Explanation;</u></h3>
- Adding affixes to the beginning or end of the root or base word may build new words by modifying existing words.
- <em><u>A suffix is a type of affix or an element placed at the end of a word to form a derivative, such as -ation, -fy, -ing.</u></em>
- <em><u>Prefix is another type of affix that is added at the beginig of a word to adjust or qualify its meaning, e.g. re- and non-.</u></em>
