Answer:
The correct answer is: d. Carassius is a group of different organisms with similar structures, while auratus is a smaller group of members that can only breed with another auratus.
Explanation:
Carassius signifies the name of genus. In binomial terminology it is the generic name shared by the collection of nearby families. In this case, Carassius is a genus in the family of ray-finned fishes. Auratus signifies the types of the fish and it is detailed exclusive epithet within the type. Carassius is a type in the ray-finned fish family Cyprinidae. Maximum types in this genus are usually identified as crucian carps, however this tenure often precisely denotes to C. carassius. The most well known is the goldfish (C. auratus).
A chemical defense mechanism is called bioluminescence.
As mentioned in the reaction, Ceratium fusus undergoes a special chemical reaction at night which helps them defend themselves from predators. During this reaction, light is produced inside a living organism. However, this type of reaction does not produce heat although it does produce light.
<h3>
What is bioluminescence used for?</h3>
The most well-known purpose of bioluminescence is to defend the organism against attacks by predators. This is because the light confuses or frightens predators.
Besides confusing the predator, the light can also alert large predators to approach the location of the organism, in this way this large predator will eat the predator that is threatening the organism which in our question, is Ceratium fusus.
Many marine organisms use the phenomenon of bioluminescence for their defense, in particular marine invertebrates, vertebrates, certain micro-organisms as well as certain fish and fungi.
Hence concluded that the bioluminescence characteristic of Ceratium fusus is being described.
