What grows exponentially in real life?
What grows exponentially in real life? One of the best examples of exponential growth is observed in bacteria. It takes bacteria roughly an hour to reproduce through prokaryotic fission. If we placed 100 bacteria in an environment and recorded the population size each hour, we would observe exponential growth. How do I calculate exponential growth? […]

How does convection currents affect weather?
How does convection currents affect weather? During convection, cooler water or air sinks, and warmer water or air rises. This movement causes currents. These currents move water all around the earth, bringing warm water to cooler areas and vice versa. This redistributes thermal energy and causes changes in the weather. What are convection currents and […]
What are the 5 defense mechanisms?
What are the 5 defense mechanisms?

All defence mechanisms are responses to anxiety and how the consciousness and unconscious manage the stress of a social situation. How do you break […]
How long do electric pencil sharpeners last?
How long do electric pencil sharpeners last? How long can a sharpener last? Most electric pencil sharpeners could last as long as 3000 times before the battery gets low. If you are lucky enough to have an electric sharpener that uses AC too, it might last longer than that. Which electric pencil sharpener is best? […]
What is the correct flow of energy?
What is the correct flow of energy? The flow of energy is always unidirectional. The energy passes from primary producers to primary consumers. From the primary consumers, the energy is passed to secondary consumers and then to tertiary consumers. How does the energy cycle work? The energy is used to continue life’s processes (i.e. reproduction, […]
Can eye muscles get sore?
Can eye muscles get sore? When your eyes are not properly aligned, you may experience double vision, which the brain rejects. To compensate for the misalignment and keep your eyes moving in sync, the extraocular muscles have to work overtime. Eventually, these tiny muscles become strained and fatigued, leading to a range of painful symptoms. […]
