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

a video that shows penguin species that have different mating dances

Explanation:

The question is incomplete as it does not have the options which are:

a video that shows penguin species that have different mating dances

The reproductive isolation is the factor which allows the species to evolve and form a new species, therefore, this factor is used to describe a species.

The reproductive isolation refers to a mechanism in which the species are isolated to not interbreed with the individual of other species. The reproductive isolation could be due to behavioural, psychological, physical or genetic differences. evolved as an adaptation.

In the given cases, the penguin species which shows different mating dances is considered to be reproductively isolated as the different dance rituals evolved as behaviour to prevent them from mating.

Thus, the selected option is correct.

its B i just took the test on edge

Explanation:

stratosphere: as the altitude increases, the air temperature increases. the stratosphere has a layer of ozone, called the ozone layer. this layer absorbs most of the ultraviolet radiation from sunlight. this results in the stratosphere being warmer.

explanation:

b,bacteria convert nitrates

into nitrogen gas.

d,plants and animals take in

and use nitrogen compounds.

e,bacteria break down waste    

products and return nitrogen  

to the soil.

a,bacteria convert atmospheric

nitrogen to ammonia.

c,bacteria convert ammonia

to nitrites and nitrates.
