From the information in the passage and the diagram, what can you conclude about the function of mitochondria? They take instructions from DNA and make proteins.

They break down sugars to provide energy for the cell.

They are membrane-bound organelles with a second, folded membrane inside to provide extra area for cellular respiration.

They are organelles, which are a group of flattened membrane sacs stacked on top of each other.

They break down sugars to provide energy for the cell.

Explanation: I’m pretty sure please tell me if I’m wrong

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
