Question 8

What is an amphibian?

Answer 8

The word Amphibia is derived from Amphi and bios (double life) due to the fact that they live part of their life in water and part of their life on land. They have a varying number of limb pairs (0-2) and all have a skull which articulates with the vertebral column (the spine or backbone) by two rounded condyles, differentiating them from reptiles who only have one. They have a highly complex skin which embodies multiple types of glands resulting in various secretions.

Question 9

What are two features of amphibians?

Answer 9

• Need Water To Breed
• Breathe through moist skin and lungs

Question 10

What are Birds?

Answer 10

Birds are warm-blooded vertebrates, they all have feathers, lay hard-shelled eggs and have strong, yet lightweight, bones.

Question 11

What are two features of birds?

Answer 11

• Have beaks and no teeth
• Have feathers and wings

Question 12

What are fish?

Answer 12

‘Aquatic vertebrates that have gills throughout life and limbs, if any, in the shape of fins’.

Question 13

What are two facts about fish?

Answer 13

• Have fins (if limbs) and gills
• (Usually) covered in scales

Question 14

What is a reptile?

Answer 14

All reptiles are cold-blooded ectotherms, have scales and reproduce either by laying eggs or giving birth to live young. Some reptiles are aquatic animals, although most live on land.

Question 15

What are two facts about reptiles?

Answer 15

• Have dry scaly skin
• Breathe only through lungs

Question 16

What are mammals?

Answer 16

Mammals are vertebrates with hair, mammary glands used to suckle young with milk, a diaphragm, three bones in the middle ear, and a lower jaw made up of a single pair of bones that articulates in a unique way with the skull.

Question 17

What are two facts about mammals?

Answer 17

• Covered in hair
• Suckle their young

Question 18

What are annelids?

Answer 18

Annelids are segmented worms from the phylum Annelida. They are characterised by the ring-like segments around their body. The term annelid comes from the Latin word annellus meaning ‘small ring’. Annelids are found worldwide in ocean, freshwater, brackish water and soil environments.

Question 19

What are molluscs?

Answer 19

These animals all have soft bodies that do not contain bones. Most molluscs have a hard, chalky shell. However, some, like squid and cuttlefish, may have a fragile shell located inside the animal, or the shell may be absent, as in some sea slugs.

Question 20

What are crustaceans?

Answer 20

Although they are extremely varied, all crustaceans have a body divided into a head, thorax and abdomen, two eyes and two pairs of antennae, a hard exoskeleton and jointed, paired appendages. They vary from microscopic plankton less than 1 mm long to enormous crabs and live on both land and sea despite being originally aquatic.

Question 21

What are arachnids?

Answer 21

Arachnids are animals that have:

eight walking legs
one or two main body parts
often predatory habits
simple eyes
a skeleton outside the body

Question 22

What are insects?

Answer 22

Insects are animals that have:

a pair of antennae
six walking legs
a body divided into three parts
a skeleton outside the body
mouthparts which are adapted for particular diets.

Question 23

What are bacteria?

Answer 23

Bacteria are single celled prokaryotic (no nucleus) microorganisms that are either free-living in soil or water or diseases of plants or animals.

Question 24

What is archaea?

Answer 24

microorganisms which are similar to bacteria in size and simplicity of structure but radically different in molecular organization. They are now believed to constitute an ancient group which is intermediate between the bacteria and eukaryotes. Archaea and bacteria have several important differences. For example, archaea have cell walls without peptidoglycan, while bacterial cell walls contain peptidoglycan. Archaea also show a closer evolutionary relationship to eukaryotes than to bacteria.

Question 25

What is Eukarya?

Answer 25

Eukarya is a domain or a large taxonomy group that is made up of organisms that contain a nucleus within their cells. A nucleus is a type of organelle found in a cell that contains the genetic information of that cell

Question 26

What is a protozoan?

Answer 26

Protozoa are a polyphyletic group of single-celled eukaryotes, either free-living or parasitic, that feed on organic matter such as other microorganisms or organic debris. Historically, protozoans were regarded as “one-celled animals”.

Question 27

What is an autotroph?

Answer 27

An autotroph is an organism that creates its own food.

Question 28

What is a heterotroph?

Answer 28

A heterotroph is a life form that cannot create its own food and relies on other organisms.

Question 29

What is an endothermic organism?

Answer 29

An endothermic organism uses energy to internally regulate its own temperature.

Question 30

What is an ectothermic organism?

Answer 30

An ectothermic organism relies on external/environmental factors to regulate its own body temperature.

Question 31

What is an endothermic reaction or process?

Answer 31

An endothermic reaction or process is one which absorbs heat from its surroundings.

Question 32

What is an exothermic reaction?

Answer 32

An exothermic reaction has energy released in the form of light or heat.

Question 33

What is a unicellular organism?

Answer 33

Unicellular organisms consist of a single cell.

Question 34

What is a multicellular organism?

Answer 34

A multicellular organism consists of more than one cell.
