Your teacher gives you an unknown protist to classify that is currently inactive. The protist appears to have long lash-like
appendages protruding from its cell surface. Which kind of locomotion can we expect from this protist? (1 point)

O The appendages of this protist will move in a sweeping motion like oars to actively propel the protist forward.
The appendages of this protist will move back and forth like a wagging tail to actively propel the protist
forward

Sexual selection example; The brightness of the feathers of a peacock. You may also see similar traits in other birds, where some dance and show off bright feathers to attract a mate, where other build nests. These specific traits do not increase their chance of survival, and are not learned. They increase their fitness because they increase their chances of reproduction and passing on their genes.
Survival of the fittest = Survival of those who survive, and reproduce
