Q

The name “Tursiops truncatus” includes which of
the following ranks?
a. Genus and species
b. Kingdom and phylum
c. Class and order
d. Species and subspecies

A

a. Genus and species.

Here’s why:

Genus: “Tursiops” refers to the specific group of bottlenose dolphins. All bottlenose dolphins, regardless of specific region or variation, belong to the genus Tursiops.
Species: “truncatus” further narrows down within the genus Tursiops to the common bottlenose dolphin specifically. Other closely related bottlenose dolphins might have different species names within the same genus.

Q

Place the following taxonomic ranks in order from
most specific to least specific. A) Order; B) Phylum; C)
Family
a. B, C, A
b. C, B, A
c. A, C, B
d. C, A, B

A) Order: This is the most specific rank, grouping closely related families with similar characteristics. For example, within the mammal class, the Carnivora order includes families like dogs (Canidae), cats (Felidae), and bears (Ursidae).
C) Family: This rank is less specific than order, containing multiple genera with shared traits. For instance, the Canidae family within the Carnivora order includes different genera of dogs like wolves, foxes, and jackals.
B) Phylum: This is the least specific rank among the three including classes like mammals, birds, reptiles, and fish.

Q

What type of body symmetry do human beings
have?
a. Radial symmetry
b. Bilateral symmetry
c. We are asymmetric
d. Quadrilateral symmetry

A

b. Bilateral symmetry

This means that if you drew a line down the center of our body, the left and right sides would be mirror images of each other. We have paired arms, legs, eyes, ears, nostrils, etc., arranged symmetrically on either side of this imaginary line.

Q
  1. Where would you most likely find a parasitic
    flatworm?
    a. In the jungle
    b. In the ocean
    c. In the digestive system of another animal
    d. In a temperate forest
A

c. In the digestive system of another animal

the majority of parasitic flatworms depend on a host for their survival. Finding them in a jungle, temperate forest, or even the open ocean without a host is much less likely.

Q

What do butterflies and lobsters
have in common?
a. They are both mollusks.
b. They are both annelids.
c. They are both arthropods.
d. They are both cnidarians.

A

c. They are both arthropods.

17
Q

According to one estimate, there are 5 million
animal species on Earth. If this estimate is correct,
how many of these species are invertebrates?
a. 4.75 million
b. 3 million
c. 2 million
d. 1 million

A

a. 4.75 million.

If there are 5 million animal species on Earth, and over 95% of all animal species are invertebrates, then:
Number of invertebrate species = 5 million * 0.95 = 4.75 million

18
Q

Some invertebrates, like jellyfish, spiders, and
crabs are predators. What does this mean?
a. They cannot move.
b. They eat other animals.
c. They are parasites.
d. They live underwater.

A

b. They eat other animals.
Therefore, the defining characteristic of predators, including invertebrates like jellyfish, spiders, and crabs, is that they actively hunt and consume other animals for their sustenance.

19
Q

How can a notochord differ from a proper
backbone?
a. A notochord can be made of stiffened tissue
b. A notochord can be located along an animal’s belly,
instead of its back
c. A notochord can be located on the outside of an
animal’s body
d. A notochord can disappear once an animal reaches
full maturity

A

d. A notochord can disappear once an animal reaches full maturity.

20
Q

Which term most accurately describes your body?
a. Endothermic
b. Ectothermic
c. Mesothermic
d. Hypothermic

27
Q

What are the 7 Animal Phyla?

A
  1. Porifera (Sponges): These sessile filter feeders lack true tissues and organs, and their bodies are covered with pores for water flow and nutrient absorption. Examples include bath sponges and glass sponges.
  2. Cnidaria (Jellyfish, Anemones, Corals): These radially symmetrical creatures have stinging cells called nematocysts for defense and prey capture. Examples include jellyfish, anemones, sea corals, and hydras.
  3. Platyhelminthes (Flatworms): These bilaterally symmetrical worms are flattened dorsoventrally and often parasitic, living inside or on other animals. Examples include tapeworms, flukes, and planarians.
  4. Annelida (Segmented Worms): These bilaterally symmetrical worms have bodies divided into ring-like segments and move using muscular contractions. Examples include earthworms, leeches, and bloodworms.
  5. Mollusca (Snails, Clams, Octopuses): These bilaterally symmetrical creatures have soft bodies often enclosed within a hard shell and possess specialized foot structures for movement. Examples include snails, clams, oysters, octopuses, and squids.
  6. Arthropoda (Insects, Spiders, Crabs): animals with jointed limbs, hard exoskeletons, and segmented bodies. Examples include insects, spiders, crabs, shrimps, and millipedes.
  7. Chordata (Vertebrates): This phylum boasts animals with a notochord (flexible rod), dorsal nerve cord, and bilateral symmetry. It includes all vertebrates like fish, amphibians, reptiles, birds, and mammals.
28
Q

What is a species

A

A group of organisms that can interbreed and produce fertile offspring under natural conditions.

29
Q

What is the difference between plant cells and animal cells?

A

Plant cells: Have a rigid cell wall made of cellulose, which provides support and protection. Animal cells lack a cell wall.

30
Q

What domain to animals belong to?

A

Animals belong to the domain Eukarya. Eukarya is one of the three main domains of life on Earth, alongside Bacteria and Archaea

31
Q

What is the largest animal ever and the smallest animal?
