Global air circulation cells move air "clockwise in the Northern hemisphere and counterclockwise in the Southern hemisphere".
<u>Answer:</u> Option B
<u>Explanation:</u>
Global circulation is defined as the global connection of winds, through which the requisite heat transport from tropical latitudes to polar latitudes carried out. Each hemisphere comprises with three cells, such as Hadley, Ferrel and Polar cell, air circulation take place in this through the complete depth of the troposphere.
The worldwide circulation cells allow passage of air in clockwise pattern in the northern hemisphere while in southern hemisphere circulate in counter-clockwise pattern from equator to poles but in different directions and at different latitudes.
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.
