Explanation: The green algae population will increase because if the crustaceans are killed, there is no consumption of algae hence resulting in increased levels of algae.
After that the blue gill fish that is the consumer of crustaceans will also be affected, their numbers will start to reduce with time and they might die off unless they move to another habitat so the option "D" is wrong
Homeotic genes regulate the development of structures. Logically, then, the mutation of this gene must result in improper structure development, such as structures in abnormal places. The answer is C.
