A good passing current is a small wave for example.
Answer:
organelles are very similar to present-day bacteria, suggesting a common ancestor.
Explanation:
Some evidence suggests that some organelles like mitochondria and chloroplasts within eukaryotes were once used to be independent eukaryotes.
Endosymbiosis theory says that ancestral prokaryotic cells engulfed bacteria like cyanobacteria which with time evolved into mitochondria and chloroplast. Molecular evidence also proves that these organelles were once prokaryotic organisms because they show similar genetic makeup and ribosome type.
So these organelles are similar to present-day bacteria showing that they have a common ancestor.
<span>Disaccharides need to be broken down into their component subunits (monosaccharides) before their absorption. The reaction that breaks them up is hydrolysis and it is done by enzymes- <span>glucosidases. Glucosidases are located on the brush border of the small intestine, attached to the surface of the epithelial cells. After the catalyzation of these disaccharides, the epithelial cells take up the monosaccharides and transport them inside using ATP energy. From there they are transported into the bloodstream.</span></span>
