T or F, Comparative study of animals reveals that form & function are closely correlated

Answer 3

True

Question 4

T or F, complex organisms like us have highly folded internal surfaces for exchanging materials

Answer 4

True

Question 5

animals are composed of cells organized into…

Answer 5

tissues with different functions

• which makes the organs
• which makes the organ systems

Question 6

Epithelial Tissue

Answer 6

covers the outside of the body & lines the cavities within the body

Question 7

Connective tissue

Answer 7

binds & supports other tissues

Question 8

Loose connective tissue

Answer 8

connects epithelia to underlying tissues & holds organs in place

Question 9

Cartilage

Answer 9

strong and flexible support material

Question 10

Fibrous connective tissue

Answer 10

found in tendons, which attach muscles to bones

Question 11

Ligaments

Answer 11

Answer 12

stores fat for insulation and fuel

Question 13

considered connective tissue

Answer 13

Blood & Bone

• osteon are bone cells
• bones are made out of calcium carbonate

Question 14

Muscle tissue

Answer 14

consists of long fibers, which contract in response to nerve signals

Question 15

Skeletal muscle

Answer 15

responsible for voluntary movement

Question 16

Smooth muscle

Answer 16

responsible for involuntary body activities

ex. digestive system

Question 17

Cardiac muscle

Answer 17

responsible for contraction of the heart

Question 18

Answer 18

• senses stimuli and transmits signals throughout the animal

- contains Neurons & Glial cells

Question 19

Neurons

Answer 19

nerve cells that transmit nerve impulses

Answer 22

transmits hormones to receptive cells throughout the body via blood

Question 23

Organisms use what to maintain an
internal balance regardless of external
environment?

Answer 23

homeostasis

Question 24

Thermoregulation

Answer 24

the process where animals maintain a tolerable internal temperature

Question 25

ectotherms

Answer 25

• tolerate greater variation in internal temperature

- cold blooded can’t regulate body temperature

Question 26

endotherms

Answer 26

• active at a greater range of external temperatures
• warm blooded can regulate body temperature
• more energetically expensive than ectothermy

Heat regulation in mammals

*skin, hair, & nails

Question 28

Some animals can regulate body temperature by…

Answer 28

• adjusting their metabolic heat production
• moving or shivering
• some ectotherms can shiver to increase body temperature
