To what category of animals do the yellow sponges in this photo belong?
Correct Answer
A. Porifera
Explanation
The yellow sponges in the photo belong to the category of animals called porifera. This is because porifera, also known as sponges, are characterized by their porous bodies and lack of true tissues or organs. Sponges are filter feeders that live in aquatic environments and play important roles in marine ecosystems. They are known for their ability to filter water and extract nutrients from it.
2.
The majority of invertebrate species belong to which category of animals?
Correct Answer
A. Arthropods
Explanation
The majority of invertebrate species belong to the category of arthropods. Arthropods include insects, spiders, crustaceans, and other related organisms. They are characterized by their jointed limbs, segmented bodies, and exoskeletons. Arthropods are incredibly diverse and can be found in various habitats worldwide. They play essential roles in ecosystems as pollinators, decomposers, and prey for other animals. With over a million described species, arthropods make up the largest phylum in the animal kingdom.

____________________ are animals with an exoskeleton, segmented bodies, and jointed appendages. Insects, crustaceans, and arachnids belong to this category of animal.
Correct Answer
A. Arthropods
Explanation
Arthropods are animals with an exoskeleton, segmented bodies, and jointed appendages. This category includes insects, crustaceans, and arachnids. Arthropods are characterized by their hard outer covering, which provides protection and support for their bodies. Their segmented bodies allow for flexibility and movement, while their jointed appendages enable them to perform a wide range of actions such as walking, grabbing, and flying. Arthropods have a high level of diversity and can be found in various habitats around the world.
4.
__________________________ are vertebrates that undergo a metamorphosis during some time during their lives.
Correct Answer
A. AmpHibians
Explanation
Amphibians are vertebrates that undergo a metamorphosis during some time during their lives. This means that they go through a transformation from an aquatic larval stage, such as a tadpole, to a terrestrial adult stage. This process allows them to adapt to different environments and lifestyles. Butterflies also undergo a metamorphosis, but they are not vertebrates. Iguanas and reptiles do not undergo metamorphosis. Therefore, the correct answer is amphibians.
5.
What is a characteristic of all living organisms?
Correct Answer
A. They are made of cells
Explanation
All living organisms are made of cells. Cells are the basic structural and functional units of life. They carry out essential processes such as metabolism, growth, reproduction, and response to stimuli. Whether an organism is unicellular or multicellular, it is composed of cells. Cells provide the necessary structure and organization for living organisms to carry out their functions and maintain homeostasis. Therefore, the characteristic of being made of cells is universal to all living organisms.

Correct Answer
A. Echinodermata
Explanation
Echinodermata is the correct answer because it is the phylum of marine animals that have radial symmetry and include starfish, sea urchins, sand dollars, and sea cucumbers. Reptilians, nematodes, and porifera are not phyla that fit the given description.
13.
Some animals don't fall neatly into one category or another. The platypus is one example. They lay eggs instead
of giving live birth. Why do scientists consider a platypus a mammal. Check ALL that apply.
Correct Answer(s)
A. Platypus young drink mother's milk
B. They are warm-blooded
C. They have fur
Explanation
The platypus is considered a mammal because it possesses certain characteristics that are common to mammals. These include the fact that platypus young drink their mother's milk, indicating that they are capable of lactation. Additionally, they are warm-blooded, meaning that they can regulate their body temperature internally. Lastly, they have fur, which is a defining characteristic of mammals. The fact that they lay eggs does not exclude them from being classified as mammals, as there are other mammals, such as the echidna, that also lay eggs.
14.
I'm warm-blooded, lay hard-shelled eggs, and have feathers. What am I?
Correct Answer
A. A bird
Explanation
The given characteristics of being warm-blooded, laying hard-shelled eggs, and having feathers are all unique to birds. Birds are the only animals that possess these specific traits, making them the correct answer.
15.
There are more invertebrate species than vertebrate species?
Correct Answer
A. True
Explanation
Invertebrates are animals that do not have a backbone, while vertebrates are animals that have a backbone. In general, there are more species of invertebrates than vertebrates. This is because invertebrates make up the majority of the animal kingdom and include a wide range of diverse groups such as insects, worms, mollusks, and crustaceans. Vertebrates, on the other hand, include mammals, birds, reptiles, amphibians, and fish, which are fewer in number compared to the vast array of invertebrate species.
16.
I'm an annelid?
Correct Answer
B. False
Explanation
The statement "I'm an annelid" implies that the speaker is an annelid, which is a type of segmented worm. However, since the speaker is a human and not a worm, the statement is false.
17.
I'm a segmented worm. What phylum do I belong to?
Correct Answer
A. Annelida
Explanation
The correct answer is annelida. Annelida is the phylum that includes segmented worms. These worms have bodies made up of repeating segments, which gives them their characteristic segmented appearance. They can be found in various habitats, including marine, freshwater, and terrestrial environments. Annelids play important roles in ecosystems as decomposers and as a food source for other organisms. Examples of annelids include earthworms, leeches, and polychaete worms.
18.
I'm warm-blooded and do not drink mother's milk. I must be a ...
Correct Answer
A. Bird
Explanation
The statement mentions that the organism is warm-blooded and does not drink mother's milk. This indicates that the organism is not a mammal, as mammals are warm-blooded and typically drink mother's milk. Reptiles and amphibians are also not warm-blooded. Fish, on the other hand, are cold-blooded and do not drink mother's milk. Therefore, the only option left is a bird, which is warm-blooded and does not drink mother's milk.
19.
I'm cold-blooded lay jelly-like eggs, and undergo a metamorphosis in which I change from being an underwater animal to being a land animal. I must be a...
Correct Answer
A. AmpHibian
Explanation
Amphibians are cold-blooded animals that lay jelly-like eggs and undergo metamorphosis, transitioning from an aquatic lifestyle to a terrestrial one. This process involves significant physical changes, such as the development of lungs and limbs. Reptiles, fish, mammals, and birds do not typically exhibit this type of metamorphosis, making amphibians the correct answer.
20.
There are no warm-blooded animals that live in oceans.
Correct Answer
B. False
Explanation
The statement is false because there are warm-blooded animals that live in oceans. Examples of warm-blooded marine animals include dolphins, whales, and seals. These animals have the ability to regulate their body temperature, which allows them to survive in the cold ocean waters.
21.
Which of the following animals exhibits radial symmetry?
Correct Answer
B. Jellyfish
Explanation
Radial symmetry means that the body parts of an organism are arranged around a central axis. Jellyfish are a prime example of radial symmetry, as their body structure allows for multiple planes of symmetry through their central axis. This contrasts with the bilateral symmetry seen in animals like tigers, eagles, and kangaroos, where the body has a right and left side that are mirror images.
22.
There are more arthropod species than mammal species.
Correct Answer
A. True
Explanation
Arthropods are a diverse group of animals that include insects, spiders, crustaceans, and more. They are incredibly abundant and have adapted to various environments, resulting in a large number of species. On the other hand, mammals, while diverse, have a lower number of species compared to arthropods. Therefore, it is true that there are more arthropod species than mammal species.
