Which structures are similar in function, but do not guarantee that the organisms are related?
analogous structures
homologous structures
vestigial structures
transitional structures

The correct option is Analogous structures.

Explanation: Analogous structures are structures that do not guarantee that the organisms are related. The structures are similar as a result of they evolved to try to the identical job, not as a result of they were transmitted from a common ancestor.

example: Sweet potatoes and potatoes,  both have the function of food storage.

the answer is alpha particles hope i you

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
