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.
No it is fake it lives for about 120 days that means 4 months
1. Water is abioitic and is needed by every living organism Soil is abioitic and is needed by plants Trees and other plants release water vapor from their leaves (a process called transpiration) that create humidity (which in turn influences how much rain falls in an area) The climate in an area influences the special adaptations that plants and animals have. For example: warm fur coats and thick layers of fat to keep warm in cold climates, animals in dry, hot climates (desert) have large ears to release heat and cool down. Biotic factors also influence abiotic factors. Animals produce waste (go to the bathroom) which in turn will become nutrients in the soil.
2. decrease heat will affect biotic factors, like animals, warmth.
Hope this helped :)
