Answer: true

Explanation: Sleep is important to a number of brain functions, including how nerve cells (neurons) communicate with each other. In fact, your brain and body stay remarkably active while you sleep.

Question: Jezelyn needs to create a project that shows reproductive isolation in action and decides to make a video. Which of the following would make the best project?

a video that shows a large river that has penguin populations on both sides

a video that shows penguin species that have different mating dances a video that shows

a penguin that is laying eggs a video that shows penguins in a tidal pool and an open ocean

Answer:

The right option is a video that shows penguin species that have different mating dances.

Explanation:

Reproductive isolation is the inability of animals of closely-related species to interbreed with one another successfully as a result of various differences which can be ecological, behavioral, psychological, or genetic. From the question given above, the difference in the mating dances of the penguin species will not allow the animals to unite and mate. This condition describes reproductive isolation. Reproductive isolation is caused by mating differences, sterility or environmental barriers that eventually lead to the adaptive splitting into two species. However, reproductive isolation is not sufficient but internal barriers to gene flow are required for speciation to evolve.

Among other finds, he observed and collected the variety of small birds that inhabited the islands, but he did not realize their significance, and failed to keep good records of his specimens and where they were collected.
