About This Quiz

Believe it or not, some creatures out there don’t have to rely on a backbone or a bony skeleton to get them through life as we do, but today we’ll be looking at the animals that do! We and the rest of the organisms out there that use a backbone are called vertebrates, and in the following quiz we’ll be testing your knowledge on them and what sets them apart from invertebrates! Good luck!

    The metabolic wastes that build up in the blood of a fish are removed by which organ?

    • Kidneys

    • Pancreas

    • Small intestine

    • Anus

    Correct Answer
    A. Kidneys
    Explanation
    The kidneys are responsible for removing metabolic wastes from the blood in fish. The kidneys filter waste products such as ammonia, urea, and carbon dioxide from the bloodstream and excrete them as urine. This process helps to maintain the proper balance of chemicals and fluids in the fish's body. The pancreas is involved in the production of digestive enzymes, the small intestine is responsible for absorbing nutrients from food, and the anus is the opening through which waste materials are expelled from the body.

    The jawless fishes are different from jawed fishes because jawless fishes

    • Have paired fins

    • Don't have paired fins

    • Don't have unpaired fins

    • Have a swim bladder

    Correct Answer
    A. Don't have paired fins
    Explanation
    Jawless fishes are different from jawed fishes because they lack paired fins. Paired fins are a characteristic feature of jawed fishes, which include both bony fishes and cartilaginous fishes. Paired fins, such as pectoral and pelvic fins, provide stability, maneuverability, and control during swimming. In contrast, jawless fishes, such as lampreys and hagfishes, have unpaired fins, which are not divided into two distinct halves like paired fins. Instead, they have a single, continuous fin along the body. This is one of the key differences between jawless and jawed fishes.

    In the evolution of the vertebrates from invertebrate chordates, the likely sequence of events is:

    • Adult urochordate > larval cephalochordate > jawless fishes > bony fishes > cartilaginous fishes

    • Adult cephalochordate > larval urochordate > bony fishes > jawless fishes > cartilaginous fishes

    • Larval urochordate > cephalochordate > jawless fishes > jawed fishes > bony fishes

    • Osteichthyes > chondrichthyes > urochordate > agnathan > ceopahlochordates

    Correct Answer
    A. Larval urochordate > cephalochordate > jawless fishes > jawed fishes > bony fishes
    Explanation
    The correct answer is larval urochordate > cephalochordate > jawless fishes > jawed fishes > bony fishes. This sequence is based on the evolutionary progression of vertebrates from invertebrate chordates. Urochordates, such as sea squirts, are the closest relatives of vertebrates. Cephalochordates, like lancelets, are primitive chordates that resemble early vertebrates. Jawless fishes, such as lampreys and hagfishes, are the earliest known vertebrates. Jawed fishes, including sharks and rays, evolved later. Finally, bony fishes, which include most modern fish species, are the most advanced group of vertebrates.

    The function(s) of the intestines of a fish:

    • Is mechanical digestion

    • Are mechanical and chemical digestion

    • Are chemical digestion and absorption of nutrients

    • Are mechanical digestion and absorption of nutrients

    Correct Answer
    A. Are chemical digestion and absorption of nutrients
    Explanation
    The intestines of a fish are responsible for the processes of chemical digestion and absorption of nutrients. Chemical digestion refers to the breakdown of food into smaller molecules through the action of enzymes, while absorption of nutrients involves the uptake of these smaller molecules into the bloodstream for use by the fish's body. This is an essential function for the fish to obtain the necessary nutrients from its diet and support its overall health and growth.

    The scales of a cartilaginous fish like sharks:

    • Are called dermal denticles

    • Resemble teeth

    • Feel like sandpaper

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    The scales of a cartilaginous fish like sharks are called dermal denticles, which resemble teeth and feel like sandpaper. This means that all of the statements are correct. Dermal denticles are specialized scales that provide protection and reduce drag in the water. They have a tooth-like structure and a rough texture, similar to sandpaper, which helps sharks swim more efficiently and navigate through the water.

    The term for an organism whose offspring develops internally, recieving nutreitns from the mother, is:

    • Oviviparious

    • Viviparous

    • Oviparous

    • None of the above

    Correct Answer
    A. Viviparous
    Explanation
    The term "viviparous" refers to an organism whose offspring develops internally and receives nutrients from the mother. This means that the offspring is born alive and fully formed, rather than hatching from an egg like in oviparous organisms. Oviviparious refers to organisms that lay eggs but retain them inside the body until they hatch, while oviparous refers to organisms that lay eggs externally. Therefore, the correct answer is viviparous.

    What do amphibians use to sense vibrations on land?

    • Tympanum and columella

    • Diencephalon

    • Olfactory tract

    • Optic lobe

    Correct Answer
    A. Tympanum and columella
    Explanation
    Amphibians use the tympanum and columella to sense vibrations on land. The tympanum is a thin, circular membrane located on the side of the head, and it acts as the eardrum. When sound waves hit the tympanum, it vibrates and transfers these vibrations to the columella, which is a small bone connected to the inner ear. The columella then transmits the vibrations to the inner ear, allowing the amphibian to detect and interpret sounds in their environment.

    The spiral valve is:

    • A structure in the heart that prevents blood from flowing backwards in sharks

    • A corkscrew shaped structure that increases the surface area of the shark intestine

    • The covering of the gills in the bony fishes

    • A corkscrew shaped structure that increases the surface area of the perch intrestine

    Correct Answer
    A. A corkscrew shaped structure that increases the surface area of the shark intestine
    Explanation
    The spiral valve is a corkscrew-shaped structure that increases the surface area of the shark intestine. This allows for more efficient absorption of nutrients from the digested food. The spiral shape of the valve creates a longer pathway for the food to travel through, maximizing the contact between the food and the intestinal walls. This increases the absorption surface area, allowing the shark to extract more nutrients from its food.

    The sensory organs that sense electrical fields in sharks are called:

    • Lateral Line System

    • Nares

    • Kidneys

    • Ampullae of Lorenzi

    Correct Answer
    A. Ampullae of Lorenzi
    Explanation
    The sensory organs in sharks that sense electrical fields are called ampullae of Lorenzi. These organs are located in the shark's snout and are sensitive to electrical currents produced by other animals. They help sharks detect prey, navigate, and communicate with other sharks. The ampullae of Lorenzi contain specialized cells that can detect even the smallest electrical signals, allowing sharks to locate hidden or camouflaged prey in their environment.

    Primitive jawless fishes that are the earliest vertebrates in the fossil record are called:

    • Ostracoderms

    • Placoderms

    • Cephalaspidomorphi

    • Chondrichthyes

    Correct Answer
    A. Ostracoderms
    Explanation
    Ostracoderms are considered to be the earliest vertebrates in the fossil record. They were primitive jawless fishes that lived during the Paleozoic era. Ostracoderms had a bony armor covering their bodies, which provided protection. They lacked jaws and had a simple structure, with a notochord instead of a backbone. Ostracoderms eventually became extinct, but they played a significant role in the evolution of vertebrates, as they were the first animals to possess a true skeleton.

    Which of the following is NOT a characteristic of a frog?

    • Chromatophores (pigment cells)

    • Strong limb and limb girdles

    • Non-poisonous glands

    • Vertebrae interlock

    Correct Answer
    A. Non-poisonous glands
    Explanation
    Frogs are known for their poisonous glands, which produce toxins as a defense mechanism. These toxins can be harmful or even deadly to predators. Therefore, the presence of non-poisonous glands would be a characteristic that is not typically associated with frogs.

    Ichthyosaurs and Pleisosaurs are...

    • Land rovers

    • Swimmers

    • Birds

    • Reptiles

    Correct Answer
    A. Swimmers
    Explanation
    Ichthyosaurs and Pleisosaurs are swimmers because they are both extinct marine reptiles that lived during the Mesozoic era. Ichthyosaurs were fish-like reptiles with streamlined bodies and fins, while Pleisosaurs were large aquatic reptiles that resembled modern-day seals. Both species were well-adapted to life in the water, with streamlined bodies, powerful tails, and flipper-like limbs, allowing them to swim efficiently and hunt for prey underwater. Their fossil remains and anatomical features provide evidence of their aquatic lifestyle, confirming that they were indeed swimmers.

    The frog's circulatory system contains...

    • A two chambered heart; single circuit

    • A two chambered heart; double circuit

    • A three chambered heart; single circuit

    • A three chambered heart; double circuit

    Correct Answer
    A. A three chambered heart; double circuit
    Explanation
    The frog's circulatory system contains a three-chambered heart, which means it has two atria and one ventricle. This allows for the separation of oxygenated and deoxygenated blood to some extent. The circulatory system in frogs is also a double circuit system, meaning that the blood passes through the heart twice in each complete circuit. This allows for efficient oxygenation of the blood and delivery of oxygen to the body tissues.

    A critical difference between bony fishes and cartilaginous fishes is

    • The presence of lungs or a swim bladder in bony fishes

    • The presence of a lateral line system in sharks

    • That most sharks have color vision

    • The presence of jaws in sharks

    Correct Answer
    A. The presence of a lateral line system in sharks
    Explanation
    The correct answer is the presence of a lateral line system in sharks. The lateral line system is a sensory organ found in cartilaginous fishes like sharks. It consists of a series of fluid-filled canals and sensory cells that detect changes in water pressure and vibrations in the surrounding environment. This system helps sharks to locate prey, navigate, and detect potential threats in their surroundings. Bony fishes, on the other hand, do not have a lateral line system.
