The correct answer is - C. genus and species.
The final scientific name of an animal represents two things, its genus, and its species.
The first name is the genus of the animal, in this case we have Canus. The second name is the species of the animal, in this case nipponicus.
All living organisms are classified in a same manner: kingdom, phylum, class, order, family, genus, species.
Since the name Canus reminds me a lot of Canis, I will take the wolf as an example:
Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Carnivora
Family: Canidae
Genus: Canis
Species: C. Lupus
Answer:
Sea urchins have a unique relationship of oxygen and carbon-di-oxide.
Explanation:
Sea Urchins spread oxygen in a unique way. They take in oxygen by staying inside water. Oxygen enters the body through their gills and tubed feet. CO2, which is waste is released through the anus. They get oxygen only through diffusion, i.e. diffusion of oxygen into the organism. Oxygen diffuses in body through the canals and carbon dioxide diffuses back into the canals. Urchins also have the capability to cope up with rising CO2 levels in the sea.
The correct answer is foot.
Mollusks have more diverse forms in comparison to any other animal phylum. They comprise, the slugs, snails, and other gastropods; squids and other cephalopods; clams and other bivalves; and other lesser known but identically different subgroups.
The cephalopods like octopuses and squids possess the head, which is prominent and the foot that has been amended into tentacles. The cephalopods have an absent or diminished shell and exhibit the most advanced nervous system of the invertebrates.
The answer would be C. Thomas Hunt Morgan continued the genetic research of Gregor Mendel, but Morgan used fruit flies.
