Answer: When Ionic bonds involve a cation and an anion. The bond is formed when an atom, typically a metal, loses an electron or electrons, and becomes a positive ion, or cation. Then ions produced are oppositely charged and are attracted to one another due to electrostatic forces.
Explanation:
Social fish may not hold territories but they do jockey for position in the group, and a certain amount of chasing and aggressive display is normal. But if the group is sufficiently large and contains a good balance of males and females, schooling fish shouldn’t cause one another serious harm.
Cichlid fish are the classic examples of territorial fish. Territories may be used to control access to food, to impress females, or as safe places to rear young. Problems occur when there isn’t enough space for both territory holders and the other fish in the community. Unable to leave the aggressive fish’s territory, the other fish end up being harassed, damaged, even killed.
Answer/Explanation:
Two unaffected parents can have affected children, that means cystic fibrosis must be a recessive trait.
The two parents must each have one copy of the cystic fibrosis allele, but are themselves unaffected. By chance, the son (shaded) inherited both of these copies and is affected. The daughter either inherited one or zero copies of the cystic fibrosis allele, as she is unaffected.
