What does FST of 1 mean? no sharing What is the bottleneck effect give an example? The bottleneck effect is an extreme example of genetic drift that happens when the size of a population is severely reduced. Events like natural disasters (earthquakes, floods, fires) can decimate a population, killing most individuals and leaving behind a […]
What is the largest excretory organ in our body?
Why can I not float?
Why can I not float? Hicks explained not everyone can float — it depends on body density and their ability to displace enough water to float. People with smaller or muscular body types tend to have trouble. RelaxNSwim further explains fat is less dense than muscle and bones, so fat floats more easily. Does holding […]

What happened to the energy in the pendulum?
What happened to the energy in the pendulum? In a simple pendulum with no friction, mechanical energy is conserved. Total mechanical energy is a combination of kinetic energy and gravitational potential energy. As the pendulum swings back and forth, there is a constant exchange between kinetic energy and gravitational potential energy. Does the weight of […]
