Evidence for evolution reveals that closely related organisms have many (blank)<br>characteristics.​
Mamont248 [21]

Evidence for evolution reveals that closely related organisms have many similar  physical and genetic characteristics.

Explanation:

Closely related organisms have similar physical features and genetic sequences.

When both the physical and genetic features are similar, these organisms are referred to as homologous structure.They are similar, as their evolutionary path is the same.

Example: bones from the birds and arms of the humans, have evolved more or less similarly so they are homologous structure.

In other cases, the organisms might be closely related, but their genetic structure might have a slight change. Due to this change there might be difference in the physical structure.

Example: the chimpanzee and  human have different physical structure even though their evolution have taken the same path and they are closely related.

How many moles of O₂ are needed to react completely with 35.0 mol of FeCl₃? *
galben [10]

Answer:

52.5 mol O2

Explanation:

4 FeCl3 + 6 O2 -> 2 Fe2O3 +6 Cl2

4 mol FeCl3      -> 6 mol O2

35.0 mol FeCl3 -> x

x= (35.0 mol FeCl3 * 6 mol O2)/4 mol FeCl3

x=52.5 mol O2
