Contain DNA.

Explanation:

Living cells are classed as either prokaryotic or eukaryotic. Which of the following characteristic(s) identify both cell types, eukaryotic cells and prokaryotic cells?

have a nucleus. Only eukaryotic cells have a nucleus. are produced by division of another cell. This applies to both cell types. contain cytoplasm. This applies to both cell types. comprise most multi-celled organisms. This corresponds to eukaryotic cells. are the smallest unit of living matter. This applies to both cell types, since it is the definition of cell. contain DNA. This applies to both cell types, although the DNAs are different. have membrane-bound organelles. Only eukaryotic cells have a membrane-bound organelles. mostly single-celled organisms. This corresponds to prokaryotic cells.

What’s the question

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
