Answer:
A) Phanerozoic
Explanation:
In the given question, the chart about the evolution of insects has not been provided but based on the previous knowledge, this question can be answered.
The geologists have divided the time scale into many variables in which Eon represent the longest time scale period which has lasted for the millions of year.
The Phanerozoic eon represents the time scale during which first visible life evolved and began around 542 million years ago and is present until today. The insects belong to the arthropod group which evolved during a smaller time scale called Devonian period.
Since the insects evolved around 479 million years ago which falls under the Phanerozoic eon, therefore, phanerozoic is the correct answer.
Thus, Option-A is correct.
Dependent and Independent variables are regarded as variables in mathematical and statistical modeling and of course in some other aspects.
The independent variable is this case is the amount of salt.
- In this kind of scenario, one can think of independent and dependent variables in terms of cause and effect.
- An independent variable is the variable we assume to be the cause, while a dependent variable is assumed as the effect.
- Therefore, with this case, the amount of salt would cause a decrease in the number of plants.
- While the effect of increasing the amount of salt would be seen in the number of plants.
