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.
Answer:
A
Explanation:
because active transport uses energy to move against a concentration gradient from an area of low concentration to that of of high concentration.
Within an individual organism, the specific combination of alleles for a gene is known as the genotype of the organism, and (as mentioned above) the physical trait associated with that genotype is called the phenotype of the organism.
