Answer:
Angiosperm
Explanation:
The mitochondria of flowering Angiosperm plant are the largest. The size of these mitochondria varies from 1.86 million bp to 2.4 million bp. It is also the most complex one as it carries large number of repeating units which allows multiple permutations for recombination. This allows generation of mitochondria of varying sizes with in the same species.
It is least gene dense as the inter regions are highly expanded. One of the most distinguishing feature of these mitochondria's are that they contain polypeptides. These polypeptides are basically non functional but have potential to evolve into functional one.
If lots of things were changed (independent variable) then you wouldn’t know what caused the trend(s) in your results so you have to control all but one variable so you know that you are just changing the one thing so that is the only thing that could cause the trend. I hope that made sense
The unit of time based on the revolution of the Earth around the Sun is called a Year.
The unit of time based on the Earth spinning around completely once on its own axis is called a Day.
