<span>Answer: “Comparing the mitochondrial DNA between different eukaryotes to see how closely they are related.”</span>
The endosymbiotic theory focuses on the origin of two eukaryotic organelles that have bacteria characteristics (mitochondria in animals and chloroplasts in plants). These two are s are believed to have developed from symbiotic bacteria.
<span>In designing an experiment that would support the endosymbiotic theory, the statement that would provide the best evidence is comparing mitochondrial DNA between different eukaryotes to see how closely they are related.</span>
The cell membrane is composed of a phospholipid bilayer.
The cell membrane is primarily composed of a mix of proteins and phospholipids
Phospholipids are a major component of cell membranes. They a head and a tail. The head is hydrophilic (attracted to water) and the tail is hydrophobic (repelled by water).
They form a bilayer in which their hydrophilic heads face the aqueous cytosol and extracellular fluid while their hydrophobic tails face away from the cytosol and extracellular fluid.
The lipid bilayer is semi - permeable
