According to the endosymbiotic theory of the origin of eukaryotic cells, how did mitochondria originate? a) when a protoeukaryote engaged in a symbiotic relationship with a protocell

b) from infoldings of the plasma membrane, coupled with mutations of genes for proteins in energy-transfer reactions

c) from the nuclear envelope folding outward and forming mitochondrial membranes

d) by secondary endosymbiosis

e) from engulfed, originally free-living proteobacteria

e) from engulfed, originally free-living proteobacteria

Explanation:

The bacterium was captured by a eukaryotic cell and then the cell evolved into the mitochondria we know today!

interphase   is the cell cycle stage in which the cell acquires nutrients, creates and uses proteins and other molecules and starts the process of cell division by replicating the dna. it is the longest stage in the eukaryote cell cycle.

the following   can go wrong during interphase:   a base pair could be mismatched during the duplication process causing a mutation.   correct answer: c

explanation:

9.9 years

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
