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.
Hi there!
The answer is 4) determining the true age of rock layers.
Relative dating is only used to determine the rocks in sequential order from oldest to newest, absolute dating can give an estimated time to the age of the rock.
Hope this helps!
Answer:real remains
Explanation: because of real time
Answer:
1,000 daughter cells
Explanation:
The meiosis process can form up to 4 daughter cells: 250 x 4 = 1,000 cells.
