The team of Hunt had designed an experiment to test the hypothesis of the effect of BPA on mice. The daily doses of BPA was administered into the female groups of mice for 3, 5 and 7 days and then the genetic abnormalities which occured during meiosis, chromosome division or egg formation were studied.
The steps followed in this experiment in order are as follows:
- Observation- The mice eggs in plastic cages when washed using harsh soap showed problems during the cell division stage which caused genetic abnormalities.
- Question- If the bisphenol A from the plastic affected mice in the damaged cages.
- Hypothesis- If the frequency of the genetic abnormality was affected by the exposure to bisphenol A.
- Prediction- The level of exposure of mice to bisphenol A was proportional to the increase in genetic abnormalities.
Passive transport because Passive transport is a movement of biochemicals and other atomic or molecular substances across cell membranes without need of energy input. Unlike active transport.
The variable that is changed/controlled in a scientific experiment .
Answer:
This process, called satiation, increases the chance that cicadas will escape being eaten for long enough to survive and reproduce. ... It comes from a phenomenon known as the Allee Effect: the smaller a population gets, the less likely its members are to find one another and reproduce.

The seven periodical cicada species are so named because, in any one location, all of the members of the population are developmentally synchronized—they emerge as adults all at once in the same year. This periodicity is especially remarkable because their lifecycles are so long—13 or 17 years.
