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.
B,
predators can help limit prey populations? i’m not sure on that one.
parasites don’t want to kill their host because it relies on its host’s body and body functions. such as a tick on a dog.
i really hope this helps a little
The primary producers creatures that makes their own food like plants.
Answer AND Explanation:
In spite being called the resting phase, many cellular processes take place during this phase. One of the most important of these is chromosomal replication in which each chromosome produces an exact copy of itself. The chromosomes are not visible as discrete structures but instead they appear as diffuse tangle of threads called chromatin.
Another important event is the formation of new organelles like mitochondria. There is also a build up of energy stores which is necessary to drive the mitotic process.
