The independent variable in this experiment is the time the experiment took. This is because both the temperature and the number of cooked eggs can be affected during the process of the experiment.
Temperature of the water can be affected by the temperature of the eggs when they are first lowered into the water. This would decrease the temperature of the water, making it a depended variable.
The number of eggs cooked can be affected by the temperature. This would mean that the number of cooked eggs could differ depending on the temperature, meaning that it is a dependent variable.
Geological change will not cause a mass extinction, because it happens on a too big scale - on the scale of millions of years. During such long time, it is more likely that other causes will influence the survival of extinction of species, such as climate change or environmental disasters, and even if there is a small influence, it would not be significant next to other causes.

CO2 + H2O + ( sunlight ) = glucose + O2
The process of turning off and on of genes is known as gene regulation.
Explanation:
When the gene is turned on, it instructs the cells to construct a particular protein. The proteins are the molecules that build your body with collagen, tendons, and bones or keratin in your hair.
The gene regulatory proteins allow the individual genes of an organism to be turned on or off . in different cell types there are different selections of gene regulatory proteins. The patterns of the gene expression gives each cell its unique characteristics.
Each cell produces or turns on only a fraction of its genes. the remaining genes are repressed or turned off. this process is known as gene regulation. The signals from the environment or from other cells activate proteins called transcription factors.
