Answer:
What can be deduced of cell that have densely packed mitochondria and the cristae are very closely together is that its function requires large amounts of energy.
Explanation:
Mitochondria are cellular organelles in charge of energy production. In these organelles occurs oxidative phosphorylation and electron transport chain, whose final product is ATP, an energy molecule.
A <u>cell with a large number of mitochondria, whose crests are very close together and tight, belongs to a tissue that has a lot of activity and its energy requirement is high</u>.
An example of cells with densely packed mitochondria are skeletal muscle and heart muscle.
